Do-it-yourself Daewoo Matiz ignition lock repair

In detail: DIY Matiz ignition lock repair from a real master for the site my.housecope.com.

On any car, the ignition switch is an important component, if it is inoperative, it will be impossible to start the engine. If the motorist is faced with the problem of an inoperative device, there can be no other way out, except for replacing the contact group of the ignition switch of the Daewoo Nexia car. In this article, we will take a closer look at the replacement process with all the nuances.

Before we talk about how to remove and change the ignition cylinder or contact group on the lock of a Daewoo Nexia and Matiz car, we will briefly consider a theoretical question. The manufacturer Daewoo, whose vehicles are quite common among domestic consumers, marks the ignition lock as a mechanical type locking element equipped with a contact group. As practice shows, this component often breaks down and requires repair, this information is confirmed by motorists in numerous reviews on the network.

New contact group at Daewoo Nexia

If there is a need to repair or replace the ignition switch, contact group or cylinder on Nexia or Matiz models, it is not at all necessary to pay money for this at the service. You just need to remove the device and disassemble it, and you will find the basic repair recommendations below. But before that, let's figure out what are the causes and symptoms of a device malfunction.

All reasons for the failure of the ignition lock on Daewoo Matiz and Nexia cars are conventionally divided into two groups - electrical and mechanical. One of the main electrical reasons why a contact group or larva needs to be replaced and repaired is overloading the elements. As a result of the fact that the car owner equips his vehicle with additional electrical appliances and devices that consume more power, a voltage passes through the contact group for which it was not originally designed.

Accordingly, for a certain time, the metal of the group can withstand a large current, but subsequently the device begins to become covered with carbon deposits, and usually it forms on the top of the contact, but inside. As a result, it may be impossible to clean the contact group, in fact, as well as to repair it, all that remains is to change it.

In order to prevent overloading of this element, it is necessary to connect all additional equipment only via a relay. In this case, the current will not be able to overload the devices and the contacts of the group will be intact. But it should be noted that the failure of the contact group is not always due to the actions of the motorist, sometimes it is just a factory defect. This problem is more relevant for VAZ vehicles than for Daewoo Nexia and Matiz, but nevertheless, the starter contact sometimes burns out.

Contact group of ignition Nexia

Another reason why the car owner is faced with the need for repair is a short circuit in the vehicle's electrical circuit. Usually this rarely happens, but sometimes it happens that a large current damages the contacts of the group and the device fails. In addition to electrical, there are also mechanical causes of breakdowns, which also necessitate the repair of Daewoo Nexia and Matiz. One of the main mechanical reasons is the wear of the contact tracks or the contacts of the group themselves, which inevitably leads to the replacement of elements. This problem occurs as a result of the aging of the device as a whole, this is quite normal and expected, but sometimes the reason may be low quality metal.

In practice, the wear of the group tracks on Daewoo Nexia and Matiz cars was recorded after five months of their operation. That is, the metal elements of the device have worn out so much during this time that furrows began to appear on them. The element as a whole ceases to function normally, and when the ignition switch is disassembled, a whole handful of metal shavings will most likely be found in it. It is impossible to repair such a malfunction, it is only necessary to remove the lock and replace the contact group as a whole.

Ignition cylinder with key

Also, mechanical faults include a breakdown of the contacts themselves or other components of the group. For example, on some domestically produced cars, the starter contact is made in the form of an iron tongue, therefore, each time the engine is started, this contact extends on top of the other and bends. Over time, the element simply breaks off or will not be able to press against the fixed contact of the device.

The next reason for mechanical damage can be called a violation of the structure of the entire group as a result of the fact that the device heats up. If the ignition lock as a whole gets warm, then this indicates an overload, which we mentioned earlier. The device heats up as a result of the fact that a large current passes through it. In the event that the body of the group is of low quality and plastic, then as a result of overheating, the contact tracks may move slightly, respectively, subsequently they will break off.

One of the main signs of malfunction of the cylinder or the contact group of the ignition lock is the simultaneous inoperability of many elements of the electrical system. This occurs as a result of the fact that a certain energy consumer or even several are connected inside the device through each separate contact. For example, through the ignition, dipped and main beams, dimensions, turn signals, rear lights, a radio tape recorder or interior lighting can be powered.

It can be various electronic devices, such as parking sensors, navigators, video recorders, etc. In the event that a certain contact through which power is transmitted to consumers burns out, it will not work to start one or another equipment (the author of the video on how to replace the lock cylinder is PRO.Garage).

In the event of a breakdown of several devices, which, as it may seem, are in no way connected with each other, the cause of the breakdown almost always lies in the cylinder or the contact group of the ignition switch. Of course, the electrical equipment on Daewoo Nexia and Matiz cars can also be connected to the fuse box, and then in case of a breakdown, first of all, it is necessary to check the fuse itself. In any case, everything is individual here.

After analyzing the principle of operation of the larva and the contact group of these cars, it is possible to determine other signs of their malfunction, which will lead to the need for repair:

  1. Failure of the starter. When you try to start the engine of a Daewoo Nexia car, you will not even hear the click of the relay, neither the control nor the retractor. The lack of clicks is due to the lack of voltage that passes through the contact group.
  2. Failure of electricity consumers, which, as it may seem, are in no way connected with each other. But all these consumers always function in one key position in the lock.
  3. Another sign is if the devices did not work, and then suddenly suddenly start to turn on when you try to move the key in the lock. It should be noted that the key must be in one position. As you might guess, the elements of the contact group in this case can come into contact with undamaged surfaces and the current can pass through them, but not for long (the author of the video about replacing the device with your own hands - House Territory).

The procedure for repairing and replacing the ignition lock cylinder on the Daewoo Nexia is generally not particularly laborious.If you are used to repairing the car yourself, then you will not have any problems with the replacement.

The larva is selected in accordance with the article, the procedure for performing the actions is as follows:

  1. First you need to remove the negative terminal from the battery. Once done, use a Phillips screwdriver to remove the plastic steering wheel cover bolts. The cover must be removed.
  2. Then you need to disconnect the connectors that are connected to the contact group with screws. This procedure is carried out using two screwdrivers - longer and shorter, since the required bolt is in a very inconvenient place for dismantling. It is located inside the switch itself.
  3. Using a wire, you need to push the lock of the larva through a special hole, at the same time the switch itself should be rearranged to position 2. Having done this, you can achieve that the larva comes out about half a centimeter from the case; to remove it, you just need to get the element.

Next, you can start installing the new component. But remember that after this operation, the lock will be opened with one key, and the trunk with another. Not every car enthusiast will like this, so the only way out of the situation is to buy a set of larvae for both the ignition lock and the luggage compartment, as well as doors. Of course, the repair procedure in this case will take a long time, especially since more money will have to be spent on replacement, but this is the only way out.

If you want the key to remain one, but you don’t want to change the larvae in the trunk and doors, then there is one option, but let's make a reservation right away - it will not work for Daewoo Nexia car owners manufactured in Korea. The bottom line is to replace the secrets of the new castle with the secrets of the old one. To do this, turn the inside of the cylinder to the end, use a screwdriver to push the catch and disengage it, then carefully remove it with a spring. There is also a retainer on the opposite side, it can fall out, so be careful, you need to turn the same operation with a new larva. Evaluate the secrets themselves - if they are the same in size, then they must be replaced one by one, while not confusing them (if you confuse them, you will not be able to turn the key).

So, the new cylinder must be installed with the ignition key into the housing, while remembering that the switch itself must be activated to position 2. During installation, you must press the latch with the pin. In the event that you purchased a high-quality larva, then these actions should not cause problems. But if you decide to save a little and buy a lower quality version made in China, then the installation process can be delayed. If you believe the reviews of Daewoo Nexia car owners, sometimes such larvae cannot enter the body.

If you need to replace only the contact group, then in this case you can perform all the necessary work without dismantling the ignition lock. You only need two flat head and Phillips screwdrivers. Having prepared the tools, you can begin the repair process.

  1. Open the hood and disconnect the negative terminal from the battery.
  2. Further, as in the previous case, you need to unscrew the bolts securing the plastic lining in the area of ​​the steering wheel.
  3. Use a flat head screwdriver to detach the plug and then remove the upper steering column shroud.
  4. After these steps, you need to dismantle the O-ring located on the lower casing, for this, unscrew the four screws.
  5. Disconnect the harness that is installed on the block, then insert the key into the lock and turn it to position 2.
  6. Next, unscrew the bolt with which the device is attached, and the element itself will need to be removed from the lock itself. Instead of this group, a new one is installed, all further actions specified in the instructions must be performed in the reverse order.

Learn more about how to perform this procedure on your own - find out from the video (the author of the video is Evgeny Kuznetsov).

-Remove the cover under the steering wheel, these are five screws.

Image - DIY Matiz ignition lock repair

-For convenience, we remove the steering wheel. We pull Bibon towards ourselves, there are two wires and a nut for 24. It is not necessary to remove the steering wheel, but it is more convenient, since there is no airbag.

-Remove the turn signal block by unscrewing two screws. Here, there is not a big nuance. Before removing the steering wheel, pull out the turn signal handle mechanism, it just snaps into place. If this is not done, then the retainer can be broken and the turn signals will stop turning off automatically when the steering wheel is returned. I did not know this and naturally broke it, now turn off the turn signals manually or buy a new turn signal lever.Image - DIY Matiz ignition lock repair

- Disconnect the three wire plugs.

-Remove the contact group by unscrewing a thin screw from the lock case

-Insert the ignition key into the lock, exclusively in position 2

Image - DIY Matiz ignition lock repair

-In a thin hole on the body of the lock, we drive a knitting needle, awl or thick needle. This is for depressing the steering latch latch of the lock.

- After that, the insert clicks out a little, and then you need to pull it out using force.

Now we start to collect. The hardest part is to insert the new insert back. Many people write that this is one piece of cake, 15 minutes and you can go, but this is all a lie.

- First, file with a file, the silumin tongue of the insert, but not much, sideways, so that it would be easier for him to enter.

- Then insert a screwdriver inside the lock case and press down the steering latch catch. At the same time, you need to take a thin needle and try to fix this retainer, on the other hand, through a thin hole, from which the very stem that originally broke off comes out.

-Put the ignition key to position 2 and try to drive the insert back into the ignition lock, while holding the latch in the lower position with a needle through a thin hole.Image - DIY Matiz ignition lock repair

Recently I ran into a problem, at one unpleasant moment the Daewoo Matiz car stopped starting. The symptoms were as follows - the key in the ignition lock rotated easily and freely, without clicking and returning the key from the start position. In position II, the control lamps on the signal panel came on after the first turn and remained on even after the key was removed from the ignition lock. Suspicions fell on the contact group of the ignition lock and the ignition lock itself. The following are the stages of dismantling the contact group and the lock cylinder.

Step 1. Unscrew the 5 screws at the bottom of the steering column cover.

Step 2. Remove the upper and lower parts of the steering column and see the ignition lock with a contact group (to the left of the ignition lock housing)

Step 3. To remove the contact group, you need to unscrew the only recessed screw in the ignition switch housing and disconnect the contact group.

Step 4. To remove the ignition lock cylinder from the housing, insert the key into the ignition lock and turn it to position II. Then, into the hole, 2-3 cm from the right end of the ignition lock, insert a small hex key or drill about 2 mm in diameter - the larva will jump out of the case.

And here it is the cylinder of the ignition switch:

In my case, the problem was that the rod connecting the ignition lock cylinder and the contact group broke off - silumin and uneven casting.

A new larva was purchased in the store and all actions are repeated in the reverse order. The whole operation of disassembling the assembly takes about 15 minutes. When installing the contact group in place, do not be afraid to apply considerable force. You can buy a diploma from us quickly in Kiev

it turned out to be removed, but the new one does not climb into any. against something rests. the tongue of the steering shaft lock was pressed down - all the same, something was in the way.

Maybe the latch on the larva itself rests on something or experiment with the position of the larva relative to the body?

Hello, I unscrewed the bolt, took out the contact group, pressed it into place as shown, the larva jumped out 2 cm and the dalis does not want to take off in any way! Something is blocking it, whatever one may say, it still does not remove it completely, help ... what's the problem? "

the whole problem is that when removing the insert of the lock, the steering wheel lock tongue sometimes shoots out. (or moves a little) you TAKE a rectangular screwdriver and from the side of the insert insert, pull the tongue towards the seat until a characteristic click. Sometimes this does not work, the retainer from the silumin breaks there. Nuno, remove the shear bolts that secure the lock and press the tongue on the table, the insert will rise, and do not forget that the insert must be inserted with the key turned to position 2. good luck

It is pulled out really with some effort, but there is no need to be afraid. The fact is that some posts are misleading, which say that the larva "pops up". Nothing jumps out there, it just frees itself so that it can be removed with some effort.

I am telling you how to install the larva back, since I have not found a clear description anywhere.

The problem lies in the spring loaded steering wheel lock frame. If you look inside the castle without the larva, you can see that it "interferes" with us in two places. The first place is on the outside of the cylinder, in the place where the large petal on the larva enters, the second is in the center. To install the larva, you need to lower the frame with a screwdriver until it stops. But the problem is that when you remove the screwdriver, the frame immediately comes back. Therefore, on the reverse side (from the one from which the contact group is put on), it is necessary to fix the frame in the lowered position with a thick needle.

How to fix with a needle. When the crayfish is completely lowered, a gap is formed in the upper part, and it is necessary to rest against it with the end of the needle in order to prevent the frame from returning back. If you lower the frame with a screwdriver and shine a lantern into the lock, then everything will be clearly visible.

So, we lower the frame all the way down with a screwdriver, without removing the screwdriver, from the side of the contact group we insert the needle and push it into the gap above the frame, letting go of the screwdriver make sure that the frame remains lowered. Now we take the larva with the key sticking out in it in position II and insert it as far as possible. After that, the needle pressed by the larva must be carefully removed with pliers, while pushing the larva further.

It is not always possible to keep the frame completely lowered. Sometimes she performs a little. To get around this problem, you can grind off a little corner on the larva's petal with a small file so that when the larva is inserted into place, it lowers the frame. Well, as an icebreaker crushes the ice)) you need to undermine quite a bit.

The operation is not very convenient, so there is no need to be upset that it does not work the first time. So conceived)))

Please tell me! If I can't find a maggot with the number 90221874, like mine, will the number 96618614 or 96229490 or S6460010 work?

but everything is like in the photo, the tip of the lechina broke off .. changed and now the radio tape recorder does not turn on. I don’t know what’s the matter

thanks for the article, helped a lot. special thanks to Corvex his additions to the steering wheel lock were very useful.but like Michael, the radio tape recorder does not work for me. how to solve the problem? tell

Hello! I have such a problem on the old larva there was no petal, not in any store there is no such larva without a petal Will it come to me with a petal?

Ildar, I also have no petal, how did you manage to change the larva?

I want to share my experience, the same garbage happened today. A screwdriver is needed very thin and short to remove the contact group, a good man made a wire at the machine at work, then it was worse he could not remove the larva for half a day, then he started it with a screwdriver, and since the power steering is standing and, accordingly, the steering wheel began to turn much easier and literally pressing so that the 2mm larva literally pops out. I hope my review is useful))

And I have already replaced the larva, the day everything was fine, and on the second, the key refuses to turn at all. The larva is new and original. Tell me what could be the problem? It is not possible to pull it out, since the key does not turn to position 2. Turns slightly. And the steering wheel is locked. What to do?

The same trouble as described in the article. Tell me how to pull out the broken rod?

Hello! I have such a problem on the old larva there was no petal, not in any store there is no such larva without a petal Will it come to me with a petal?
Feel free to take this larva-96618614, the petal is simply cut off with a hacksaw and it stands up like a native! I had the same problem - it was solved with a hacksaw in 20 seconds.

    And again the theory that all machines are alive is confirmed. They just hinted that it would be time to change it and here you go.

    Mom drove me a car on March 7 and left it so that I would prepare it for sale, well, and actually engaged in the sale.

    In the morning I get into the car to go to the car wash, insert the ignition key, and ... it's quiet.

    The control lamps lit up, the ignition turned on, but the starter does not turn and the key in the ignition switch turns suspiciously easily, but the main focus was ahead.

    I pull out the key from the ignition, and the lamps on the tidy are still on, and the ignition does not turn off. Here I have a little bit of @ uel, because this has not happened in my practice yet.

    Just in case, I immediately dropped the battery terminal and turned on the deductive method, began to intensively figure out what was the matter.

    Extensive experience of a well-deserved basin, told me that the problem lies in the ignition switch, or rather in the contact group.

    The situation is, of course, terrible, especially for an ordinary car enthusiast, without experience in car repair. Do not start the car, the lights are on, it is not known what to do. If you want to call a tow truck, if you want a neighbor, ask him on a tie to drag him to the service, which will definitely be closed, for today is March 8.

    But there is something to praise Moty for, because he did not die on my mother's trip to the clinic, not on the highway, not in the country, but specifically in the parking lot in the yard, in my caring hands.

    In general, I quickly disassembled the floor of the car, I got to the ignition and immediately discovered the cause of all the troubles.The ignition lock itself is connected to the contact group through a silumin rod, which has been safely broken off. That is, I turned the key to the second position, where the ignition is turned on, after which the stem broke and neither here nor there, that is, neither start the starter nor turn off the ignition.

    I did not smile at all to remove the ignition lock, and it is absolutely not clear how this can be done without an electric tool, such as a drill or a grinder, because the lock is screwed on with shear bolts that cannot be unscrewed.

    Mentally cursing that day “when I sat down at the wheel of this vacuum cleaner,” I wandered home to ask Yandex how I can live on.

    Blah ... what my surprise was when the great Internet told me that the ignition lock on Matiz is an ordinary consumable, as they say: a matter of everyday life.

    Here I greatly respect ten-kalino-priors, because our cars never get up to such a mean thing. They can creak, creak, sneeze, but they always start and drive (Lada type five, does not count)

    The fact is that the design of the ignition lock itself, although simple, is very unreliable and breaks down sooner or later.

    But there is also a joyful moment, it is not necessary to completely change the ignition lock, because there are repair inserts, that is, the lock larvae, and this circumstance greatly lifted my spirits on International Women's Day.

    Next, I will briefly describe the removal procedure, and most importantly, the installation of this very larva. Of course, there is information on the forum, but very little and not objectively.

    -Remove the cover under the steering wheel, these are five screws.

    -For convenience, we remove the steering wheel. We pull the Bibon towards ourselves, there are two wires and a nut for 24. It is not necessary to remove the steering wheel, but it is more convenient, since there is no airbag.

    -Remove the turn signal block by unscrewing two screws. Here, there is not a big nuance. Before removing the steering wheel, pull out the turn signal handle mechanism, it just snaps into place. If this is not done, then the retainer can be broken and the turn signals will stop turning off automatically when the steering wheel is returned. I did not know this and naturally broke it, now turn off the turn signals manually or buy a new turn signal lever.

    - Disconnect the three wire plugs.

    -Remove the contact group by unscrewing a thin screw from the lock case

    -Insert the ignition key into the lock, exclusively in position 2

    -In a thin hole on the body of the lock, we drive a knitting needle, awl or thick needle. This is for depressing the steering latch latch of the lock.

    - After that, the insert clicks out a little, and then you need to pull it out, using force and obscene language.

    Now we start to collect. The hardest part is to insert the new insert back. Many people write that this is one piece of cake, 15 minutes and you can go, but this is all a lie.

    - First, file with a file, the silumin tongue of the insert, but not much, sideways, so that it would be easier for him to enter.

    - Then insert a screwdriver inside the lock case and press down the steering latch catch. At the same time, you need to take a thin needle and try to fix this retainer, on the other hand, through a thin hole, from which the very stem that originally broke off comes out.

    -Put the ignition key to position 2 and try to drive the insert back into the ignition lock, while holding the latch in the lower position with a needle through a thin hole.

    Personally, on my first move and out of ignorance of the intricacies, I spent a whole hour, during which I ran home to my laptop, hoping to find out how I could hammer this fucking insert into place.

    - Then we assemble in the reverse order.

    The price of the issue came out at 1,700 rubles. This is a set of inserts for two doors, a trunk and an ignition lock with two keys. There is also a separate lock insert for 800 rubles, but it was located on the other side of the city. This information on the network of stores "Koreana" one of which was not far from home.

    Now there are two keys on the key fob, one for the ignition, the other for the door locks. Change all the locks, a big bummer, I'll give the inserts to the new owner, let him put it himself if he wants.

    In conclusion, I can say that of course I was going to do sex on March 8, but with my wife in the crib, and not with a mote in the yard. But it so happened that I had to deal with both my wife and my friend.

    I congratulate all women motorists on the past holiday on March 8 and hope that their iron friends will not present such surprises.

    How to completely change the ignition switch in a Daewoo Matiz car with your own hands. This is a fairly rare type of repair, it may be needed when your lock is jammed or, for example, there was an attempt to steal, in which the larva is heavily pounded.

    The video uses special tools, for example, a pneumatic drill, which will help to drill out the fasteners of the lock without damaging other parts (access there is extremely limited, an ordinary drill will not go through). If you do not have such a tool, then you may have to do a couple of unnecessary actions, for example, remove the steering wheel, front panel molding, but this will take you extra time.

    Video how to change the ignition switch in Daewoo Matiz (Daewoo Matiz):

    Regardless of the car model, the ignition lock (ZZ) is one of the main components. With its help, the driver can start the engine and turn off the power unit, so if problems appear in the operation of the mechanism, this is fraught with the impossibility of starting the engine. How the contact group of the Daewoo Nexia ignition lock changes and in what cases it is necessary - read more below.

    Before removing, repairing or changing the ignition switch to Matiz or Nexia, read the possible list of causes and signs of device breakdown.

    1. ZZ overload is one of the most common causes. Overload occurs due to the installation of additional devices and devices that consume high power. The problem manifests itself as a result of the fact that a high voltage passes through the contact group, for which it is not adapted. The mechanism can get very hot and eventually it will simply fail.
    2. Manufacturing defects. If the starter contact ЗЗ is made poorly, such a device will not work for a long time.
    3. Ingress of moisture into the structure.Of course, for this reason, the unit cannot lock, but, nevertheless, the ingress of moisture inside the device has a detrimental effect on its functionality.
    4. Short circuit in the electrical component of the car. This problem does not happen often, but if the high power current damages the contacts of the mechanism, it will cause it to break.
    5. Over time, the contact tracks or the group itself can wear out in the mechanism. This is normal as wear and tear is common in any vehicle. Due to wear, grooves will appear on the metal components of the structure.
    6. Mechanical damage or breakage of contacts, as well as other components of the group. It will not be possible to repair such a protection zone, the only best option would be to replace it.

    Now, briefly about the signs:

    1. Several devices refuse to work at once, which, as it might seem at first glance, are in no way connected with each other. Inside the mechanism, one or several voltage consumers are connected to each contact. For example, these are optics, turning lights, audio system, video recorders, parking sensors, interior light, etc. If one of the pins wears out, it will no longer be able to power the equipment connected to it.
    2. Inoperability of the starter unit. If you try to start the engine with the starter inoperative, you will not hear the click of the relay. In the absence of a click, it can be concluded that no voltage passes through the larva of the device.
    3. If part of the equipment does not work, but then it is abruptly activated if the driver moves the key in the lock (the author of the video about self-replacement of the mechanism is the CarDan Tv channel).

    To change the larva, you must purchase the corresponding mechanism of a specific article. Please note that you only need to buy original parts from the car manufacturer. If you buy a Chinese maggot, chances are that it will not fit into the seat as it will be larger. In this case, you will have to grind the device, and this will take additional time.

    The replacement procedure is performed as follows:

    1. First of all, turn off the ignition and open the hood. Disconnect the leads from the battery.
    2. Then, using a Phillips screwdriver, you will need to remove the screws that secure the plastic steering wheel shroud. By unscrewing the bolts, this cladding element can be dismantled.
    3. Next, you will need to disconnect the connectors connected to the contact group of the device, they are bolted. In this case, you will need two screwdrivers, one longer and the other shorter. The screw itself, which you need to unscrew, is inside the device.
    4. Now you need a wire - with its help you need to press on the fastening of the larva through the existing hole, at the same time, the ZZ must be moved to position 2. After that, you will be able to remove the larva by about 0.5 cm. Having done this, it can be completely dismantled.
    5. When installing a new cylinder, make sure that the ZZ is in position 2. Using the pin, press the mount and install the new structural member.

    If you change the larva in the ignition lock, you should also change the larvae in the luggage compartment lock and in the doors, otherwise you will not be able to open the door and trunk with the key to start the engine.

    How to replace a contact group with your own hands:

    1. First open the hood and disconnect the battery.
    2. Then, as with the cylinder, you will need to unscrew the bolts securing the shroud to the handlebar. Remove and set aside.
    3. You will now need a flat-blade screwdriver. With its help, it is necessary to disconnect the plug, and then dismantle the upper casing on the steering column.
    4. By doing this, you will be able to remove the O-ring that is located on the lower casing. Before doing this, you will need to remove four bolts.
    5. After that, it will be necessary to disconnect the block with the wiring, which is located on the plug. Having done this, it is necessary to install the key in the ЗЗ and then turn the mechanism to position 2.
    6. After completing these steps, you will need to unscrew the screw that fixes the mechanism, after which you need to dismantle the contact group from the device. When the group is dismantled, a new one is installed. The assembly procedure is carried out upside-down.

    An illustrative instruction on the topic of replacing a ZZ in a garage with a description of the main features of this process is given in the video below (the author of the video is the Repair ourselves channel).

    My favorite car gave me an unexpected and unpleasant surprise - it refused to start at the most inopportune moment. Unexpected because there were no warning signals from the car of an impending problem. Unpleasant, because the breakdown occurred on the road, and the feeling that appears at this time, I think, is familiar to many. Plus, faithful Daewoo Nexia, never let me down, for which I actually love her. But, as time goes on, there is nothing eternal and even the most reliable cars “misfire”. And my car was no exception))).
    As the saying goes, no matter how bad the situation is, you can find in it not only minuses, but pluses. And, I immediately found them, two whole - the breakdown happened before the trip to the Crimea and there was an opportunity to prepare material for this article! So, meet and rate the article on replacing the ignition lock cylinder on a Daewoo Nexia car.

    I'll start from the very beginning. By inserting the key into egnition lock and turning it all the way, I did not hear the sound of a running starter. The engine did not start and this fact made me look around. The lights on the dashboard were all shining, they did not react to the return of the key to its original position !? That is, they did not go out, and the key itself turned suspiciously easily. I think I got covered contact group of the ignition lock... This is the first thought that came to me, and as it turned out later, it was erroneous. I decided not to disassemble and possible repairs on the spot, it is better to get to the garage, there is a necessary tool, the situation is appropriate and, as a result, the mood is appropriate. And that was done. Fortunately, the contact group froze in the second phase, I just had to give the command to the starter.Having put the car “on the handbrake”, the rocker for gear shifting to neutral position, armed with a piece of wire, opened the hood. Then everything is simple, one end to the plus on the battery, the other to the small terminal on the starter retractor relay. Oops and the engine started! All that remains is to get to the garage, the main thing before starting the movement is to turn the ignition key in the lock so that the steering wheel does not lock.

    Next, about the main thing. I will change myself both in terms of spare parts, and I will tell you about the necessary tool already in the course of the description - replacing the ignition lock cylinder on a Daewoo Nexia car.

    1. Disconnect the negative terminal from the battery. Using a Phillips screwdriver, unscrew the 8 screws securing the plastic steering column covers (see photos 1,2,3,4,5). Remove the two halves of the casing.

    2. Remove the connector from contact group (photo 6). Using a short and thin screwdriver, unscrew the fixing screw, it is located on the inside of the ignition lock, so access to it is limited (photos 7 and 8). As for me, having removed the contact group (photo 9), I made sure that everything is ok with it. Connector contact group of the ignition lock not broken. By inserting a screwdriver of a suitable width into the connector and connecting the block with wires, he started the car without any problems.

    3. The reason for the breakdown, after removing the contact group, became obvious (photo 10). The shank broke off ignition lock cylinder... It is not difficult to pull out the larva, it is enough with a wire (pin) with a diameter of 2-3 mm, bent with the letter G (I used a hexagon for this), press the latch through the hole (photo 11) and at this time turn the key to the second position. If everything is done correctly, then the larva itself will come out of the body by 5 mm. You just have to pull it out completely. Perhaps some will be visited by a thought, and not easier, remove and replace the ignition switch completely, a maggot with a body !? Great idea! The truth is quite problematic, since in order to get to the mounting bolts, you will have to remove the steering column, and this is already serious work. So, I do not recommend removing the ignition lock entirely. Easier, after all remove the ignition lock cylinder and, if desired, conjure with her))).

    4. That's it! In this state, you can go to the car market or store for spare parts. We start and turn off the car with a contact group, the key in this situation is a screwdriver. 5. On sale you can find two options for solving your problem. The first option, the most common - ignition cylinder with two keys ... Second option, set of larvae - ignition lock, front doors and trunk (photo 12). What is the difference? The first option is cheaper and faster, but you have to go with two keys and periodically "poke the wrong key" into the ignition or trunk lock. The second option is laborious and more expensive, but there will be only one key))). Whom it is more convenient. The choice is yours!

    6. True, there is another way to leave one key. And besides, old and dear. True, for owners of Korean Nexias, this method is unlikely to work. But, to get acquainted with it and check whether it fits or not, it's still worth it))).
    This method consists in replacing the secrets of the new one you bought with the secrets of the old Daewoo Nexia ignition lock... To begin with, turn the inside of the larva to the stop of the latch, press on it with a screwdriver and disengage it. Attention, we do it carefully, this retainer, together with the spring, flies quite well and is very poorly located (photos 13 and 14). On the opposite side there is also a retainer-tongue, which can also fall out and get lost, remember about it (photo 15). We carry out similar work with the new larva. Compare the size of the secrets. If they are the same, then we change them in turn, without confusing places (photo 16). If you change the location of at least one, the key will not turn.

    I was really unlucky, the secrets on the new larva turned out to be three times less than on the old one.

    Everything! We carry out the assembly in the reverse order. We insert the new larva into the body, with the key in position 2, at the same time recessing the retainer with a wire (or a pin). The main thing is to beware of cheap Chinese products (I understand that it is difficult), it looks like everything is fine, but when you try to install the larva in the lock case on the steering column, problems arise, it is simply not possible to put it there. It does not help, neither a file with emery, nor a Russian mat. It is easier to borrow the upper, non-movable part from the old lock larva (from point 6 it is clear how to do this). Which I have already done several times. And only twice in all the time, the replacement went off with a bang, the face became like a dear.
