Car brands that originated in South Korea are very popular in our country. Not only new items are relevant, but also used equipment. Among the popular cars is Daewoo Nexia.
One of the weak points of the car is the ignition switch area. Motorists on the forums note that all elements included in the unit have poor operational reliability. Relatively often, the contact group of the Daewoo Nexia ignition switch forces it to be replaced due to breakdowns. It is important to monitor the condition of the electrical unit, as it is responsible for trouble-free engine starting.
What is CG
Before replacing the ignition switch contact group on a Nexia, you need to know its internal condition and operational functionality. You need to look for the group in the area of the ignition switch. When you turn the key, the dashboard and electrical appliances connected to the on-board network are gradually put into operation. And at the extreme switching position, a signal is given to send voltage to the starter.
It is important to know that professional motorist experts note that the design used for the Nexia in ignition is unsuccessful.
The block is enclosed in a plastic case consisting of two elements. Inside there are wires of different sections, commuting with each other based on the angle of the key position. Burnout of contacts often occurs. A specific brand provides several groups of electrical outlets:
- 50 – to transfer energy to the starter;
- 30 – outgoing power from the battery;
- 15 – ignition zone;
- 15a – heating fan feeding;
- Kb and Ka – used for the on-board audio system.
Refer to the operating instructions from the vehicle. It shows where the pins are located.
Subtleties of replacing the ignition switch of Daewoo Nexia and Matiz in whole and in parts
On any car, the ignition switch is an important component; if it is not working, starting the engine will be impossible. If a motorist is faced with the problem of a non-working device, there can be no other way out than replacing the contact group of the ignition switch of a Daewoo Nexia car. In this article we will consider in detail 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 issue. The manufacturer Daewoo, whose vehicles are quite common among domestic consumers, labels the ignition switch as a mechanical locking element equipped with a contact group. As practice shows, this component breaks down quite often and requires repair; this information is confirmed by motorists in numerous reviews on the Internet.
New contact group on Daewoo Nexia
If there is a need to repair or replace the ignition switch, contact group or cylinder on the 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 basic repair recommendations below. But before that, let's figure out what are the causes and signs of device malfunction.
Causes of failure
All reasons for the failure of the ignition switch 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 cylinder requires replacement and repair is overloading of 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 high current, but subsequently the device begins to become covered with soot, and it usually forms on top of the contact, but inside. As a result, it may be impossible to clean the contact group; in fact, just like repairing 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 through a relay. In this case, the current will not be able to overload the devices and the group contacts will be intact. But it should be noted that the failure of the contact group is not always caused by the actions of the motorist; sometimes it is simply a factory defect. This problem is more relevant for VAZ cars than for Daewoo Nexia and Matiz, but nevertheless, their starter contact sometimes burns out.

Another reason why a car owner is faced with the need for repairs 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 ones, there are also mechanical causes of breakdowns, which also require repair of Daewoo Nexia and Matiz. One of the main mechanical reasons is wear of the contact tracks or the group contacts 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 wore out so much during this time that grooves began to appear on them. The element as a whole ceases to function normally, and when disassembling the ignition switch, a whole handful of metal shavings will most likely be found in it. It is impossible to repair such a malfunction; you only need to remove the lock and replace the contact group as a whole.

Mechanical faults also include the breakage 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, so every time you start the engine, 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 cause of mechanical breakdowns can be called a violation of the design of the entire group as a result of the device heating up. If the ignition switch as a whole gets hot, then this indicates an overload, which we mentioned earlier. The device heats up as a result of the large current passing through it. If the group housing is of low quality and made of plastic, then as a result of overheating, the contact tracks may move slightly, and accordingly, they will subsequently break off.
Signs of failure
One of the main signs of a malfunction of the cylinder or contact group of the ignition switch is the simultaneous inoperability of many elements of the electrical equipment system. This occurs as a result of the fact that a certain energy consumer or even several are connected inside the device through each individual contact. For example, the ignition can be used to power the low and high beam lights, parking lights, turn signals, rear traffic lights, radio or interior lighting.
It can also be various electronic devices, such as parking sensors, navigator, video recorder, etc. If a certain contact through which power is transferred to consumers burns out, it will not be possible to start this or that equipment (the author of the video on how to replace the lock cylinder is PRO.Garage).
When several devices break down, 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 contact group of the ignition switch. Of course, electrical equipment on Daewoo Nexia and Matiz cars can also be connected to the fuse box, and then in the event of a breakdown, first of all you need to check the fuse itself. In any case, everything is individual here.
Having analyzed the principle of operation of the cylinder and the contact group of these cars, it is possible to identify other signs of their malfunction, which will lead to the need for repair:
- Starter failure. When you try to start the engine of a Daewoo Nexia car, you will not even hear the relay click, neither the control nor the relay. The absence of clicks is due to the lack of voltage that passes through the contact group.
- Failure of electricity consumers, which, as it may seem, are in no way connected with each other. But all these consumers always operate in the same key position in the lock.
- Another sign is if the devices were not working, and then suddenly start turning 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 can guess, the elements of the contact group can come into contact with undamaged surfaces and current can pass through them, but not for long (the author of the video about replacing the device with your own hands is Territory House).
Check and possible recovery methods
Before removing the contact group of the Daewoo Nexia ignition switch, it is necessary to carry out a check. Almost any motorist can do it independently. First of all, attention should be paid to the appearance of the plastic case. There should also be no noticeable black deposits on the contacts inside the group.
A Phillips and flathead screwdriver will help you get to the main cables and contacts. Operations are performed in the following sequence:
- dismantle the plastic housing elements, secured with countersunk screws for a Phillips screwdriver;
- remove the protective cover in the steering column area;
- fold the contacts of the connector chip away from the contact group;
- Separate the group with a flat screwdriver.
A small screw is screwed into the housing on the right. Thanks to it, a group of contacts is fixed in the ignition switch housing. It is enough to pry it to separate it from the lock.
Upon completion of the dismantling operations, we take out the parts and inspect the contacts. If melted areas are identified, replacement will be required. Installation is carried out in the reverse order of disassembly.
Relay Introduction
If you were unable to notice any damage during inspection, we recommend opening the case with a hard knife. Perhaps the damage that causes negative factors to appear is hidden inside.

Problems with power windows
The build quality of the Daewoo Nexia, unfortunately, very much depends on the factory at which the car was assembled. Most often, problems with window regulators arise on Russian-assembled Daewoos, and the components supplied to both Uzbekistan and Poland are, apparently, exactly the same. However, if problems arise with the window regulators, you need to make sure that the problem is in the electrical part. If everything is fine with the mechanics, then you should check the fuse in the mounting block.
If everything is in order with it, then most likely it is in the lift control unit. The main unit is located in the driver's door armrest. The most likely failure is failure of the control keys or lack of contact in the control unit. The fact is that the door is constantly subject to vibration, so due to poor quality assembly, the contacts may simply come off.

In this case, it is desirable that the object is sufficiently hard, but does not damage the paint layer. If you are worried about the coating of the body, you can cover the vulnerable areas with tape. And in order to bend the frame, you can use a knife, screwdriver or wedge. If the door opens with the central locking button, then you need to take a strong but fairly thin stick and push it through the opening into the passenger compartment. Next, you just need to poke the lock button with a stick and the door will open.
If, despite all your efforts, you cannot bend the frame, try removing the sealant layer from the glass. Afterwards you will need to insert a ruler or wire with a hook between the glass and the door and pick up the lock drive pin.
Once you succeed, pull it up. Before opening the Nexia, try to remember whether it was guarded.
If yes, then be prepared for the alarm to go off immediately after opening. Since you have lost your keys and fob, there will be no way to turn it off.
