The movement of any car begins with the ignition switch. And if, when you insert and turn the key, nothing happens (the starter does not turn), then the contact group has burned out. Unfortunately, this is not uncommon for Nexia.
Replacing the contact group will solve the problem. The contact tends to melt under prolonged loads. This happens because an increased electric current passes through the contact responsible for power from the battery. Periodic replacement of the contact group will not bring much success. The best solution to a recurring problem would be to modify the electrical circuit, which will unload some of the current from one contact to the other.
Replacing the ignition lock cylinder for Daewoo Nexia
What does the ignition switch contact group look like?
This part is located in the ignition switch. When you turn the key, it is responsible for supplying current to the starter and providing power to other elements of the car: the radio, the heater fan. The Daewoo Nexia uses a design solution that, according to experts, can hardly be called successful.
Let's take a closer look at the contact group. Electrical contacts are placed in a plastic case made of two parts; they are switched depending on the position of the key.
The contact group in a Korean car often burns out due to an unsuccessful design decision
Nexia’s group has 5 conclusions:
- “30”—power is supplied from the battery;
- “15” - ignition circuit;
- “15a” - heater fan circuit;
- “50” — output to the starter;
- “Ka” or “Kb” is the circuit of the original radio.

Today I started unloading the CG as I wanted, I did it for about 5 hours, nothing complicated, if you have the hands and the desire, do it, there will be fewer problems with the car. I express my gratitude to maxxx090. On Nexias, the ignition switch contact group burns out quite often. Let's try to find out what is the cause of the burnout and how to repair the contact group. What are the symptoms of a burnt Nexia contact group? Most often, when you turn the key in the ignition switch, the starter does not turn. A new contact group for the ignition switch costs about 600 rubles. (code in exist.ru - 530395, analogue - 93741069), the cost of repair is about 100-200 rubles. (replacing the contact group) But replacing the contact group will not help for long - after a while the new contact group will start to heat up in the same way and will require similar repairs
First, remove the contact group of the ignition switch
There are 5 contacts on the contact group of the Nexia ignition switch:
“30” — power supply from the battery “15” — ignition “15a” — heater fan “50” — starter “Kb” (“Ka”) — radio tape recorder
On sale there is a contact group for Nexia with 6 contacts (in addition to those described above - contact “R”).
Connection of the contact group contacts at different positions of the ignition key: Initial position of the key “I”: “30”+”R” Initial position of the key “I” + the key is recessed into the ignition switch: “30”+”R”+”Ka” Position “II”: “30”+”Ka” Position “III” “30”+”Ka”+”15a”+”15″ Starter position: “30”+”50″+”15″+”Ka”
Why does the contact group burn out on Nexia?
The answer is simple: from contact “30” to contact “15” when the ignition is on, there is a strong load, and when the starter is turned on, from contact “30” to contact “50” an additional powerful load appears. Thus, a high power current flows through contact “30,” which leads to overheating and melting of this contact. Contact “15a” has little effect on the burnout of the contact group, since power goes through it to the first three speeds of the stove, while the 4th speed goes through a separate relay.
Causes of burnout and symptoms of breakdown
A strong current passes through the ignition switch. As a result, the wiring becomes very hot and the contacts melt. A large load occurs when the engine starts, the pin marked “30” suffers the most. First of all, it doesn’t hold up; the plastic case near the contact melts.
Due to the high current that passes through the group of contacts in the ignition switch, the contacts become very hot and the plastic housing melts
In most cases, burnout of the contact group manifests itself as follows: after turning the key in the lock, the starter does not turn. When driving, it manifests itself as follows: the engine suddenly stalls, the instrument panel goes dark and the smell of burnt plastic appears in the cabin . The second sign of a breakdown is a non-working standard radio.
Analogue or original
The contact group for Daewoo Nexia goes under the code 530395 in the online store Exist.ru. You can also purchase an analogue consisting of 6 contacts (additional - “R”) under code number 93741069. The price is around 600 rubles.
The price of a new ignition switch complete with CG, but without a cylinder, ranges from 1650 to 2000 rubles. It all depends on the build. The larva is purchased separately. There are no analogues specifically for the Daewoo Nexia lock. Original numbers: GM 531318 and 530379, which are suitable for both old and new generation Nexia.

How to check and make repairs
Any car enthusiast can check the serviceability of the group of contacts in the ignition switch. Performance is determined by the appearance of the plastic case and the presence of carbon deposits on the contacts inside the group. To get to the part, it is enough to arm yourself with a Phillips and straight screwdriver.
- We remove the plastic under the steering wheel, it is secured with screws.
First you need to remove the protective plastic under the steering wheel.
The connector can be easily removed from the group of contacts with a simple screwdriver
Using a thin flat screwdriver, unscrew the screw that secures the group in the ignition switch housing
If the case is not damaged, be sure to inspect the internal contacts. To do this, carefully disassemble the case. If carbon deposits are found, remove it with a sharp knife or screwdriver. This temporary procedure will help along the way. As soon as possible, contact an electrician at a service station or replace the contact group yourself.

Daewoo Nexia - Contact Group Unloading
As practice shows, this component breaks down quite often and requires repair; this information is confirmed by motorists in numerous reviews on the Internet.
Daewoo Nexia - Unloading the Contact Group - Duration: We repair it ourselves. Unloading Daewoo headlights...
But remember that after this operation the lock will be opened with one key, and the trunk with another.
How to install a new contact group on the ignition switch?
Contact 15A does not receive a large load, so it controls the operation of only the first three speeds of the stove, and the fourth goes bypassing it, through a separate relay.
Eliminating the cause of burnout
It should be noted that replacing the contact group with a working one helps for a while. For high-quality repairs, it is necessary to eliminate the cause of burnout: reduce the current load on the contacts. You can strengthen the weak point of the Daewoo Nexia by installing additional relays according to the diagram:
When using two relays, the load on a group of contacts is halved
This method will help extend the service life of the contact group by more than 2 times. Anyone can improve the electrical ignition circuit of a Korean car.
Fines for crossing the stop line and speeding will no longer bother you!
Daewoo Nexia ND18 › Logbook › Wiring, unloading KGZZ, head light.
I investigated a common problem with Nexia - overheating of the ignition switch contact group (IGZZ). The main load on its contacts falls when the headlight is turned on.
Resolved offer several
— unloading relay on KGZZ (the relay is placed directly under the steering wheel) Nexia-FAQ
— installation of 2 relays for low and high beam (both relays are placed under the hood, the power line is taken directly from the battery, and the old wiring is left only for relay control. In one step, the steering column light switch is unloaded and voltage losses on the lamps are minimized, i.e. . for many it should shine brighter) Nexia-Club
Unloading kg on Nexia N 150
Happy New Year everyone!
Good luck to you all this year! I'm posting this topic again. I am posting this because during this time a lot of new cars have appeared on the site, and many do not know what the problem is with overheating of the KG on the Nexia. I Draw YOUR ATTENTION TO THE fact that THIS APPLIES TO OWNERS OF NEXIA N150 (there is no such problem in the N100, it has been checked, everything corresponds to the diagram). But in our car, the Uzbeks wanted to do everything correctly, but everything turned out in one place. The thing is that, looking at the headlight switching diagram, everything looks perfect, but when you get into the wiring, you find a jamb. The diagram does not correspond to what is actually there. But it turns out that contact 30 of this relay must come and be powered from wire 30, which comes from the battery. But in fact, it is powered from wire 15, which comes from the ignition, that is, from the KG. That’s why our CG heats up, since when the headlights are turned on, 13 Amperes appear on the CG, and this is a complete overkill. If anyone thinks that unloading the CG will help (as it is written on FAG), then they are very mistaken. After this unloading, your unloading relay will burn out (again, all this has been checked). There is no need to do this unloading at all, you just have to remove this jamb in the wiring, and you will forget about overheating of the CG. Once the CG burns out, it will bother you for the entire time you own the car. It only takes half an hour, but in the end there is no strain on the wiring, and the headlights shine brighter. In general, to the point, there is a headlight switch relay in the mounting block. From it comes contact 30, which should go to wire 30 (battery), but in fact it comes to wire 15 (ignition, KG). When you turn on the headlights, the KG heats up, at this moment there are 13 Amps on it, a complete overkill. You need to transfer contact 30 of the headlight switch relay from wire 15 to wire 30. 1. Here is a diagram of how it should be: 2. Here is a diagram of where we have a jamb:
3. Here is a photo of where this relay is located on the back of the mounting block, highlighted in red HEADLIGHTS:
In general, you need to cut off this 30th contact from the relay 10-15 cm from the relay itself, and throw it in a braid onto the thickest red wire (battery), it is under constant positive. There is one caveat. If you do it according to this scheme, the headlights will not go out when you turn off the ignition (I left it that way, I don’t forget to turn off the lights because the buzzer is screaming). And here is a diagram in which the headlights will go out when the ignition is turned off:
. Here you need to connect contact 86 of this relay to the ignition, that is, to the wire from which you cut off contact 30. I hope I explained it clearly enough. Well, that’s all, if you have any questions, please contact either me, or Alexey, or Nail, who did it all.
Daewoo cars and Nexia models have one common “feature” and weakness - the ignition switch contact group quickly burns out. Most likely, for the common good of all fans of this Korean car brand, it is necessary to find out what is the reason and how to repair this contact group?
To begin with, it is worth clarifying and identifying the “symptoms” of a burnt contact group of this model. Most likely, the main “symptom” is that when you turn the key in the ignition, the starter does not respond. You can buy a new contact group for the Daewoo Nexia ignition switch for 600 rubles, however, replacement most likely will not help. After some time, the replaced part will begin to heat up and then also burn out.
It is clear that simply replacing the problem will not solve the problem, and here it is necessary to understand the essence of the contact group circuit in order to identify the cause of the constant failure. It is necessary to remove the ignition switch contact group. For the Nexia model, the contact group consists of 5 contacts:
- “30” is power from the battery.
- “15” – ignition.
- “15A” – stove fan.
- “50” – starter
- “Kb” or “Ka” – radio tape recorder.
Sometimes on sale there are contact groups for Daewoo Nexia, consisting of 6 contacts (the 6th contact is “R”).
In the Contact group, at different key positions, different contacts are connected; most likely, there is no point in giving the order of these connections; most car enthusiasts know this quite well. The important question for us is why it (the contact group) burns out...
The answer is logical and simple: When the ignition is turned on, the battery puts a strong load on the ignition (from pin 30 to pin 15), and when the starter starts, the battery increases the load on the starter (from pin 30 to pin 50). As can be seen from this, the main load goes to contact 30; a high-power current overheats and melts the wires of this contact. Contact 15A does not receive a large load, so it controls the operation of only the first three speeds of the stove, and the fourth goes bypassing it, through a separate relay.
It remains to resolve the question of what to do in order to avoid burnout of the ignition switch contact group?
Most likely, the problem will be solved by connecting additional relays for general unloading. Installing such additional relays on groups 30-15 and 30-50 will help each owner never remember that there is a problem in the ignition switch contact group.
To carry out all preventive work, you must purchase in advance:
- A starter relay from a VAZ-2108 car, which is suitable for contact 30A, is even better suited to a relay from a VAZ-2110, for contact 50A. Such a part costs about 50 rubles.
- The next purchase will be a relay socket, which costs about 20 rubles.
- It is also necessary to purchase female terminals, in the amount of 4 pieces, and costing about 4 rubles.
- A pair of wires, each about half a meter long, of different colors (preferably black and red), with a total cost of 20 rubles.
- All that remains is to purchase a screw terminal and a roll of electrical tape, for a total cost of about 26 rubles.
Let's move on to practice: replacing the ignition switch cylinder
To change the cylinder, you need to purchase the corresponding mechanism of a certain article. Please note that you only need to buy original parts produced by the car manufacturer. If you buy a Chinese larva, there is a chance that it will not fit into the seat, since its size 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:
- First of all, turn off the ignition and open the hood. Disconnect the terminals from the battery.
- After this, using a Phillips screwdriver, you will need to remove the screws that secure the plastic steering wheel cover. By unscrewing the bolts, this cladding element can be dismantled.
- Next, you will need to disconnect the connectors connected to the contact group of the device; they are secured with bolts. In this case, you will need two screwdrivers, one longer and one shorter. The screw itself that you need to unscrew is located inside the device.
- Now you will need a wire, with its help you need to press on the cylinder mount through the existing hole, at the same time the ZZ must be moved to position 2. After this, you will be able to remove the larva by about 0.5 cm. Having done this, it can be completely dismantled.
- When installing a new cylinder, make sure that the 3Z is in position 2. Using the pin, press the fastener and install the new structural element.
