This article will be useful to those who want to upgrade the ignition switch (for example, start the engine with a button) or are experiencing problems with the lock. Only the electrical part of the lock is described. We will consider the ignition switch in the VAZ-2114 version. It, unlike the VAZ-2108 lock, works in conjunction with the ignition relay.
The lock has 4 positions, of which only 3 are actually used:
- 0 - all consumers are turned off (used extremely rarely)
- 1 - ignition on
- 2 - starter turned on
- 3 — parking (the key is removed from the lock)
Contacts 7 (pink) and 8 (brown) of the lock are always supplied with voltage from the battery. These wires are connected in parallel and connected in the mounting block. The division into two wires was apparently done for reliability, or it may have developed historically - these wires can be replaced with one wire.
The brown wire connects the ignition system (carburetor version), instrument panel and some other consumers. Pink is responsible for the rest of the load.
Removing and installing the ignition switch on VAZ 2108, VAZ 2109, VAZ 21099 cars
To remove the ignition switch from a VAZ 2108, VAZ 2109, VAZ 21099 car, do the following: 1. Disconnect the wire from the “-” terminal of the battery.
2. Remove the six screws securing the lower steering column housing.
3. Remove the lower steering column cover...
4... and the ignition switch trim.
5. Remove the upper steering column cover.
6. Disconnect the connector with the ignition switch wires from the wiring harness.
7. Disconnect the connector with the ignition switch wires from the ignition relay.
8. Insert the key into the ignition and turn the key to position “0” to turn off the anti-theft device. Remove the four mounting bolts (two bolts are located on top of the steering column). Remove the bracket and ignition switch. NOTE
If the bolt heads are sheared off, the bolts must be drilled out or knocked down using a screwdriver and hammer.
On some cars VAZ 2108, VAZ 2109, VAZ 21099, an ignition switch can be installed, secured with two bolts. At the top of the bracket there is a slot into which the hook on the ignition switch housing fits. 9. Install the ignition switch on a VAZ 2108, VAZ 2109, VAZ 21099 in the reverse order.

Design and principle of operation of the lock assembly
On a VAZ 2109 car, 2 standard modifications of the lock can be installed. The old one has catalog number 21080-3704005-60. It features four key positions (long), and also contains an ignition relay. The new unit with catalog number 21080-3704005-30 has only three key positions and does not have a relay.
To connect all the wires to the VAZ 2109 car lock, a contact group is used. Each of the key positions has its own blocking, and therefore consumer groups.
Contacts “30” and “30/1” are closed. All dependent power circuits are disabled.
In this position, voltage is supplied to the elements of the ignition control system. To do this, the white and brown wires are connected, and the pink wire is connected to black and blue. In this case, several groups of contacts are formed. For example, “30 INT” turns on the power supply circuit for external lighting, including high beam lighting, and the dashboard lighting. Contacts “30/1” and “15/1” provide voltage to the direction indicator lamps, reverse lights, elements of the ignition system, etc. The pair “30/1”, “15/2” powers the low/high beam headlights, fog lights , washer, fans.

The ignition relay, which was switched on in the previous step, continues to operate. The main one is a pair of contacts “30”, “50”, which provides voltage for the starter to operate. In parallel to it, circuits should be formed from contact connections “30/1”, “15/1”, as well as “30/1”, “15/2”. The consumers that are connected in this case are similar to those described for position “I”. The pink wire in the contact pair, together with the black one, is shorted to red (instead of blue).
Used to supply voltage to the components of the parking (“30/1 P”) and side lighting/dashboard lighting (“30 INT”) components. The black wire forms a closed circuit with the brown and pink wires.
The lock and its circuit perform two functions: electrical and mechanical. The essence of the first is to close certain groups of contacts based on the position of the key. From a mechanical point of view, when the ignition is turned off, the steering wheel is blocked, making it impossible to rotate. That is, the second function is protective.
Malfunctions of the ignition switch of the VAZ 2109 and their correction
Malfunctions of the ignition switch of the VAZ 2109 are quite common. This element consists of two parts: mechanical and electrical. Because of this, malfunctions of the ignition switch on the VAZ 2109 can pose a big problem for many, which they cannot cope with on their own. This publication aims to familiarize the reader with all known malfunctions of the ignition switch and explain how to fix them.
What is
First, let's look at the structure of the castle. Let's find out what it looks like, what it consists of, what its operating principle is, and so on:
- As mentioned, the ignition switch is a very important element of the VAZ 2109 car, because almost all available equipment is connected to it.
Note. Although there are components that do not depend on the lock in any way. Here they are: license plate lights, brake lights, parking lights, hazard lights, interior lights and lights on the dashboard.
- There are different types of ignition switches: new or old type. The first version without a relay has three positions and a short key, the second with a relay has four positions and a long key.
Scheme
Below is a typical diagram of the ignition switch on the “nine”.
The lock belongs to the car's ignition system. Let us note right away that if problems are observed, you can fix them yourself, because, as a rule, the “nine” is equipped with an outdated ignition system that does not require diagnostics and repair at a service station.
How to make sure there is a problem
Below is a tip on how to make sure that the ignition switch is really not working:
- We insert the ignition key and turn it to a certain position. A short circuit in the circuit must necessarily occur. We look at the diagram: if the key is in position “1”, is the external lighting or control devices working;
- It is recommended to check at all positions of the lock. If deviations from the norm are observed, there is a problem with the lock;
- You can also check the functionality of the ignition switch in the following way: turn the steering wheel, which should not be blocked. The lock on a working steering wheel should only work when the key is turned a second time from position “1” to position “2”;
- You can reliably check whether the lock works like this: take an ordinary portable lamp and connect one end to ground, the other to the lock. We turn on the ignition - if the light is on normally, then the lock is in order. If the light glows dimly or does not light at all, the lock is faulty.
Common faults
Among them, the following are in first place:
- The lock is jammed. This is even observed in the “nines” when a new lock is installed. The reason is a manufacturing defect or what is given below.
Note. The lock may also jam due to problems interacting with the starter. In this case, you need to inject a little silicone grease inside the lock and do this every time the lock jams.
- The lock may wear out over time and this will cause it to perform poorly;
- The ignition switch easily becomes unusable in the event of an unsuccessful attempt to steal a car, as well as any careless handling.
Repair and replacement
Typically, the lock can be repaired. If this fails, you will have to completely replace it (see Replacing the VAZ ignition switch on your own). Repairing a lock in most cases comes down to replacing the cylinder or contact group. If after this the problem has not been resolved or it is possible to change the entire lock, then it is better to do the latter.
Typical faults
Since the ignition switch on the VAZ 2109 performs two functions, the nature of the faults can be divided into mechanical and electrical, although most often the lock breaks down in starter mode:
- A mechanical malfunction includes jamming of the core in any position: it is physically impossible to turn the key. In this case, you can inject a little silicone lubricant inside. If this does not help, you will have to remove the ignition switch and replace it with a new one.
- Electrical faults can occur at a certain position of the key when the integrity of the electrical network in the switch is broken. If there is no contact, all system components will not work. If there is contact, but the circuit does not occur where it is needed, this is fraught with a short circuit and overheating of the circuit breaker. It may melt and a specific smell will appear (video author - MAQS MAC).

The switch, also known as the ignition switch, plays a huge role in the “starting” system of the VAZ 2114 car. It takes part in the operation of the starter, headlights, turn signals, power windows and other elements of electrical circuits. Today we will talk about the ignition switch of the VAZ 2114, the reasons for its replacement, the dismantling procedure and much more.
Purpose and device
The main purpose of the lock at first was to protect the car from theft, but:
- Now, as can be seen from practice, in order to start and steal a car, car thieves do not necessarily need to have a key, or a duplicate of it.
- To put it more clearly, the defense from the castle was previously justified, but now it is “so-so”
- Equipped with modern technologies and devices, advanced car thieves are able to hack the electrical protection of the most modern anti-theft systems in just a few seconds.
- And on the VAZ 2109, the lock cylinder or the VAZ 2109 lock itself, or its Russian analogue, can generally be called entertainment for beginners
- In fact, the ignition switch is an ordinary switch that, when you turn the key, opens or closes a certain group of contacts
- The occurrence of a malfunction in the ignition switch increases the possibility of vehicle theft by a couple of times, in addition, it creates huge problems for you and, according to the law of meanness, at a completely inappropriate moment for this
- The device of any ignition switch is similar; it consists of a lock and its contact group
- And the contact group consists of two separate plates, fixed and movable
- The movable plate moves when the key is turned in the lock and the contacts are closed in the appropriate sequence
- Already at the moment, all Russian cars successfully use switches that have a similar design and procedure for closing contacts
Troubleshooting Methods
There are two methods for detecting faults:
Ignition switch circuit
We suggest studying a visual method for determining a malfunction or breakdown of the contact elements of the ignition switch using the table.
To work, you will need a mini-tester and a multimeter in ohmmeter mode:
- Disconnect the power supply from the ignition switch. To do this, you need to remove the skin from the steering column;
- Switch your multimeter to an ohmmeter;
- On the block coming from the lock you need to find pins 7 and 4, which correspond to pins 15 and 30;
- Connect the multimeter probes to them;
- Turn the key to the “Ignition” position;
- On the block, find pins 7 and 3, corresponding to 50 and 30. Also connect a multimeter to them;
- Turn the key to the second position - Start the engine;
- If serviceability is present, the device will show zero resistance in both test cases.
Preparation
At the preparation stage, you will need to collect the necessary tools near you, which will be useful in the process of dismantling and installing a new ignition switch. You will also have to remove the steering cover and steering column shifters. Doing this is quite difficult, but we will tell you step by step about all the nuances of these preparatory activities. So you can easily figure out for yourself how to remove the ignition switch on a VAZ 2114.
Tools you will need:
- Phillips strong screwdriver;
- Open-end wrench 10 millimeters;
- Chisel;
- Hammer;
- Pliers or pliers;
- New ignition switch assembly;
- Lock mounting screws (4 pieces).
Now let's move on to the casing and switches. For more convenient work, many advise removing the steering column switches and the steering wheel itself. Dismantling the casing is performed in the following sequence:
- Disconnect the negative cable from the battery. Nobody has yet canceled the requirements for personal safety and protection against electric shocks;
- Unscrew the three screws securing the two parts of the casing. A screwdriver is useful for this;
- Unscrew the screw that connects the housing to the connector of the steering column switches;
- Remove the two screws that hold the lower housing to the steering column;
- The lever that fixes the column at the corner leads down;
- The steering wheel also goes down;
- The lower casing is then removed;
- The power supply from the emergency lights must be disconnected;
- Now you can remove the top casing;
- To dismantle the steering column switches, you need to act one by one;
- Simultaneously press both latches and thereby remove the elements from their seats;
- Disconnect them from the power supply.
Removing a faulty lock
Unscrewing the ignition switch bolts with a chisel
In practice, replacing the ignition switch on a VAZ 2114 will be impossible until you get rid of the old one. This is not difficult to do, but you will have to spend some time on your car.
- Once you have gained access to the ignition switch, or rather its housing, you will notice that the lock is attached to the steering column with four bolts. The problem is that they don't have heads.
- This phenomenon is part of the “unique” factory anti-theft system manufactured by AvtoVAZ. In fact, such a system makes it somewhat more difficult for criminals who do not have a key to start the engine. So don't scold them too much.
- These bolts are loosened with a chisel and hammer, and their removal is done using pliers.
- Next, remove the bracket from the column;
- Be sure to unplug the power supply. In general, the wiring diagram for the VAZ 2114 ignition switch is simple if you buy the lock assembled. You don't have to solder anything or figure out which wire goes where. Everything is assembled into a block, so all that remains is to insert it into the appropriate connector. That's all.
- By disconnecting the power supply, you can now finally get rid of the failed ignition switch.
Pinout of lock VAZ-2110, VAZ-2111, VAZ-2112
Pinout of the ignition switch VAZ-2110:
- comes +12V for the microphone of the sensor of the inserted key;
- the mass comes when the driver's door is open;
- +12V goes to the starter (pin 50);
- +12V goes out after turning on the ignition (pin 15);
- +12V goes out when the key is inserted to pin 5 of the BSK;
- comes +12V to illuminate the lock cylinder;
- +12V comes from the battery (pin 30);
- not used.

Installing a new device
Now you can finally proceed directly to replacing the broken or worn out ignition switch on your VAZ2114 car.
To do this, follow the following sequence of actions:
- Insert the key into the new lock and turn it to the first position. This will allow the latch, which is responsible for locking the steering shaft, to hide inside the housing structure;
- Insert the lock into place following the reverse dismantling sequence;
- Install the four retaining bolts and tighten them slightly.
Changing the contact group
Exploded view of the lock
Based on price considerations, replacing one contact group is less expensive:
- All our actions are repeated in principle, as in the case described above with removing the lock, you will have to remove the casing, and so on
- To avoid the widespread problem associated with mixing up contacts, it is recommended to number them before disconnecting (or mark them in some other way)
- This measure will save your nerves and time.
- Some models of locks have a locking ring in their contact group, and here we need an awl to pull it out
- It’s important not to forget to stick it in place later
- Then everything is put back together and screwed to the control column
That's all, all that remains is to finish watching the video and relax and change every part of the lock.
Steering lock testing
If you don't check the steering lock, you may encounter certain problems in the future. Therefore, do not waste your time on this event. It consists of removing the key from the ignition and turning the steering wheel at a slight angle.
- If there is no lock, you will need to slightly adjust the position of the lock. Make sure it fits into the groove located on the steering shaft.
- If the locking is effective, you will only need to tighten the four installed breakaway bolts until they stop. Twist until the heads break.
When the lock installation is completed and the test has passed, do not forget to connect the device to power and start the engine. If it starts, all systems dependent on the ignition switch are working, you can fully begin reassembly. Follow the reverse instructions for removing the casing and steering column switches. It would not be amiss to check the condition of certain nodes along the way. It is quite possible that some of them also need replacement or a little preventive maintenance.
Operation of the ignition switch
In general, the operation of the ignition switch is extremely simple: when you turn the key, the contact disk rotates and certain electrical circuits of the car are closed. Moreover, turning the lock is possible only when using an individual key; it is impossible to start the car with another key.
Ignition switches can have three, four or five positions:
- “Off” - in domestic ignition switches it is designated as “0”, although in some older cars this lock position was designated “I”. In modern foreign-made cars, this position is not fixed or indicated on the lock;
- “On” or “Ignition” - in domestic locks it is designated as “I”, although sometimes “II” is also found (in Moskvich cars), in modern cars this position is designated “ON” or “3”;
- “Starter” - in domestic cars it is designated as “II”, on some models you can find the designation “III” (in Moskvich cars), in modern cars it is designated “START” or “4”;
- “Locking” or “Parking” - in domestic cars it is designated as “III”, sometimes as “IV” (in Moskvich cars), in foreign cars it is designated “LOCK” or “0”;
- “Additional equipment” - in domestic ignition switches there is no such position; in foreign cars it is designated as “Acc” or “2”.
How to replace the ignition switch, check the contact group and replace it on a VAZ 2108-VAZ 21099?
Replacing the ignition switch:
Removal: 1) Starting with “The battery is a rechargeable battery,” unscrew the nut that holds the “-” terminal on the battery and then remove the terminal. (How to remove the negative terminal from the battery, see the article about “Replacing the battery on a VAZ”, in the “first” paragraph)
2) Then remove the steering column cover and both steering column switches. (How to remove the casing and both switches, see the article: “Replacing under-steering switches”)
- Further, for clarity, the operation will be shown with the steering wheel removed, but you can still remove the ignition switch without removing the steering wheel.
3) Next, insert if the lock allows it, then insert the ignition key into it and put it in position “0”.
Note! The key must be installed in this position only to disable the anti-theft device!
4) Now remove the four bolts that secure the ignition switch. If you have these bolts with a cut off head, then knock them down with a hammer and chisel. (Be sure to read the “Important!” paragraph)
Note! If that doesn’t work, then try drilling out all four bolts, but just do it carefully without damaging anything!
5) Once the bolts are loosened, use pliers to remove them from the hole.
6) Next, remove the bracket on the left side, and the ignition switch on the right.
7) Now disconnect the wire block from the electrical connector.
And finally, crawl under the dashboard, and there, disconnect the connector going from the ignition switch to the relay.
Installation: Installation of a new lock is carried out in the reverse order of removal.
Checking the contacts of the wire block:
1) First, remove the lock from the car using the text above.
2) Next, using an “Ohmmeter” or a “Multi-meter” with the “Ohmmeter” function enabled on it, connect its leads to the electrical connector and then look at the readings of the device.
Note! The device should clearly display “0”; otherwise, replace the contact group!
Replacing the lock cylinder itself or the contact group
Read
Replacing the VAZ 2109 lock cylinders requires the following tools:
In case of any breakdown, it is not necessary to completely replace the lock; if the cause of the malfunction lies in replaceable parts, then a partial repair of the lock is carried out and replacing the lock cylinders on the VAZ 2109 makes sense when the key stops spinning freely in the keyhole. Another option for partial repair is to replace the contact group; this requires a minimum of tools and little understanding of the device.
Our summary will help you understand the device:
- Nothing and no one forbids you to change the entire lock every time, and even go to a service station if you are satisfied with the price
- After removing the casing, access to the switch lock is revealed.
- In principle, the lock cylinder can already be removed at this step
- Therefore, we pull out the side pin that holds it in the lock
- This is easy to do with a narrow screwdriver (clockwise) while tapping it with a small hammer
- If the pin cannot be pulled out this way, then try to carefully drill out the cylinder using a narrow drill
- If it is more convenient for you to pull it out first, pull out the ignition switch, before you start replacing the cylinder, to do this you need to unscrew the bolts securing the ignition switch to the control column
- This must be done using a hammer and chisel because these bolts have sheared heads.
- You need to loosen them a little with a chisel, and then unscrew them with pliers, as in the photo below
Loosen the bolts securing the lock to the control column
- Now we remove the bracket and the lock itself from the column, and be sure to disconnect its electronic connector
- We unscrew the screw securing the ignition relay and remove it from under the panel
- Disconnect the connector
- Disconnect the “mass” wire
- Using a Phillips screwdriver, unscrew the screw
- Then release the latch and remove the cover, then the contact group
- So we pulled the switch
- We remove the cylinder with our own hands and the ignition switch, as already described above
- We are replacing it
- We check the operation of the lock with the newest cylinder installed, to do this we turn the ignition key
- After installation, do not forget to check the correct operation of the locking mechanism, our control shaft
- When the mechanism does not work when the control steering wheel is turned at full speed, you need to adjust the placement of the lock on the control column
- Only after adjusting the location and checking the functionality of our locking mechanism, you can tighten the bolts until the heads come off one hundred percent, use a “10” spanner for this purpose.
