Ignition key for VAZ 2106. We install a new ignition switch on the “classic”. In what cases is it necessary to replace the ignition switch?
Before you begin any troubleshooting work on your car, you should prepare a certain set of tools. In the case of removing the ignition switch on the “six” we will need:
- screwdrivers - flat and Phillips;
- awl.
However, you can do without the latter. An awl can be perfectly replaced by, for example, a miniature screwdriver, or a thin long nail with a cross-section of no more than 2 millimeters. One point should also be noted. Before disassembling the ignition switch, it is recommended to disconnect the negative terminal from the battery. Many may argue that a voltage of 12 volts is practically safe for humans.
However, do not forget that in the process of work you may well short-circuit the wires and damage any electrical equipment.
Accordingly, additional, completely unnecessary problems will appear.
Now we need to find 2 screws that secure the ignition switch itself. You will immediately notice them - at the bottom of the switch, on the left and on the right. There is very little left. In particular, you should disconnect the wires from the ignition switch contacts. Now we find a flat slot on the right, stick an awl into it, and then press on the latch, applying a certain force. Next, pry up the lock with a flat-head screwdriver and remove it from the bracket.
Pay attention to one thing. The lock should be removed without any problems. If, despite the efforts made, it stubbornly does not want to come out of the bracket, it means that you did not press the latch all the way. In this case, you should follow one simple procedure. Press the awl onto the latch, and at the same time move the key slightly from side to side, just do not turn it.
Replacing the contact group and installing the ignition switch
As mentioned above, there are several reasons why this work has to be done. One of them is burning of the contact group. In this case, there is no need to change the entire lock. At the same time, replacing the contact group will not cause you much trouble. To remove it, remove the spring ring. After this, the contact group simply drops out on its own. Now all that remains is to put a new one in its place. This should be done in such a way that the groove on the contact group exactly coincides with the rod of the secret part. After making sure that everything is seated as needed, we secure it with a spring ring.
The ignition switch connects and services many of the vehicle's electrical circuits. The operation of entire groups of voltage consumers depends on its serviceability. The device performs several important functions:
Owners of the “six” are most often interested in the following issues related to the lock:
- ignition switch connection diagram for VAZ 2106;
- replacing the ignition switch on a VAZ 2106;
- how his contact group changes.
Let's look at these topics in order.
Ignition switch circuit
The electrical wiring connected to the mechanism works according to the following scheme:
There are four lock positions.
Zero position. With it, all electrical networks are turned off, except for two terminals, indicated in the diagram in dark color.
First position. Dimensions, windshield wipers, and heater fan receive power.
Second position. Additionally, power is supplied to the ignition system, indicators and buttons on the dashboard, turn signals and starter.
Third position. Only the dimensions, windshield wipers and horn continue to receive power.
The lock mechanism interacts with several electrical circuits that combine the vehicle's electrical appliances into a single circuit. When we turn the key, voltage from the negative terminal of the battery is supplied to the ignition coil.
Since the lock mechanism is regularly used by the driver, some of its elements wear out and fail. Sometimes all you need to do is spray the lock cylinder with WD-40. However, the effect may not last long and repair work will still be required in the near future.
The ignition switch is designed as follows:
The simplest thing is to replace the faulty lock with a new one. The cost of this part for the VAZ 2106 car is low. The replacement must begin with the process of removing the old mechanism.
How to remove the lock
If the latch cannot be fully pressed, you need to simultaneously slightly turn the key left and right, without turning it all the way. This will allow you to find a position in which the latch will be squeezed out completely and the lock will easily come out. Please note that anti-theft may also interfere. It moves with the key. If you turn the key to the starter position, it will take the most convenient position for removing the lock.
Another important tip: mark how the wires were connected. This will help you avoid any confusion when installing a new device.
Replacing the contact group
Sometimes there is no need to completely change the lock mechanism. It is enough just to change the contact group.
It is located on the back of the mechanism. Attached to the body with a spring ring. You can try to remove it by hand or using a screwdriver.
We film the group itself. It consists of two plastic rings that have built-in current-carrying tracks. There is a spring inside the ring.
Over time, carbon deposits form on these tracks, which leads to failure. There is no point in messing around with this soot. It's easier to buy a new group in the store. Its cost for a VAZ 2106 does not exceed 50 rubles. 
Please note that there are different models. On some, the starter contact is attached so that when you turn the key, the contact bends. This leads to quick breakdowns. It is better to choose a model on which the contact is rigidly installed.
Installing a new part is easy. Alternately move the wires from the previous part, choosing the correct contacts. Place the key in the zero position, turn the top of the group to the left until it stops and insert it into the lock. Make sure that the blade inside the body fits into a special groove. Snap and slide on the snap ring.
Installing the ignition switch
After you have replaced the contact group or bought a new lock, it needs to be returned to its place. And this needs to be done as correctly as possible. We offer the following sequence of actions that will help you easily connect the ignition switch on the VAZ 2106:
After all the work has been completed, you can connect the negative terminal to the battery and check the functionality of the mechanism. Do not forget that when replacing the ignition switch, the VAZ must be disconnected from the power supply.
Like any car, the VAZ 2106 has strengths and weaknesses that are familiar to many car enthusiasts. Intensive use, bad roads, harsh climate do their job slowly but surely. As they say, nothing lasts forever - parts wear out, one way or another they have to be replaced. Many car owners prefer to do feasible repairs themselves. And everyone has heard about the periodic breakdown of a small but very important part - the ignition switch. If your lock is faulty, then it won’t hurt you to acquire such a useful skill as installing a VAZ 2106 ignition switch.
It’s not without reason that they say: the new is the well-forgotten old. The VAZ 2106, the well-known “six”, has been one of the most popular and popular domestic cars since the times of the Soviet Union. Over the entire production period of this model, over 4.3 million cars were produced and assembled at various factories. A real workhorse, it’s not for nothing that she still has many admirers. Until now, lively “sixes” in large numbers plow the automotive spaces of the CIS countries and neighboring countries, as well as beyond. Of course, even an old woman can get into trouble.
Structure and purpose of the ignition switch
The ignition switch (lock) on all “classic” models, including the “six”, is absolutely similar in its structure and design. Let's consider its structure and principle of operation.
Ignition switch (lock) device:
Castle structure
- Locking rod
- Frame
- Roller
- Contact disc
- Contact sleeve
- Block
- Protrusion of the contact part.
The lock mechanism is connected to many wires. They continue from the battery, connecting all the electrical devices of the car into a single chain. When you turn the ignition key, the electrical circuit is closed from the “-” terminal of the battery to the ignition coil.
As a result, the current passes through the wires to the ignition switch, through its contacts it is directed to the induction coil, after which it returns back to the “+” terminal. As electricity passes through the coil, it generates high voltage, which it transmits to the spark plug. Therefore, the key closes the contacts of the ignition circuit, thereby starting the car engine.
The ignition switch, like all spare parts, requires repair or replacement over time. And any car enthusiast will be able to cope with this, having a minimum amount of necessary knowledge.
Removing the old ignition switch
Before installing a new lock, you need to make room for it by disconnecting the old one.
Tools and Precautions
To do this we need a simple set of tools: a screwdriver and an awl.
Tools
Before you start work, do not forget about basic safety rules - disconnect the battery (remove the negative terminal).
Disconnecting the battery
Removing the ignition switch
After preparing a safe workplace, we can safely get down to business.
Using a screwdriver, unscrew the 5 screws of the steering column switch housing. After this, remove the upper and lower casing elements. Unscrew the two screws that secure the ignition switch to the housing.
Removing the casing
We insert the ignition key into the lock and turn it to the “off” (0) position to unlock the anti-theft system. To remove the lock from its seat, we find a small round hole in its left side.
Unlock
We take an awl and insert it into the hole, pressing the latch with it. At the same time, remove the ignition switch, pushing it towards you with your hand.
We take out the lock
Disconnect the wires from the terminals. If the coil of wire ends with a chip, then this greatly simplifies the task. This means that you do not have to label the wires or remember the diagram of their connection to the lock terminals for later connection. So, just disconnect the chip with the wires.
Installing a new lock
The ignition switch is disconnected. Now we can start connecting the new one.
We connect the contact group of wires
If you are lucky enough to become the owner of a chip that closes the wires, then simply connect it to the new lock.
Connecting the chip
If there is no chip, then we connect each wire separately. We take the terminal block of the new ignition switch in our hands so that the only double terminal located on it is on the right and in a vertical position. The top compartment of the double terminal corresponds to the double black wire.
Wiring pinout by color
Next we move counterclockwise. The next one to connect is the pink wire, followed by the double blue, then the brown, and the last one is red. In addition, you can figure out the location of the wires on the terminal block using the digital marks that mark the block itself. There is a designation near each terminal; let’s look at how the terminals correspond to the colors of the wires:
- 1NT – black double wire
- 30 – pink wire
- 15 – double blue wire
- 30/1 – brown wire
- 50 – red wire.
The lower part of the double terminal remains empty - as it should be. Contacts are connected.
Back of the castle
We install the lock in place and finish the job.
Now it's time to lock the new lock in its original position - to the left of the steering wheel.
So, insert the key into the lock and fix it in position “0”. Then we take the lock and insert it into its original position, “sinking” the side lock with your fingers. Now the lock is in place, so we can tighten the mounting screws and install the decorative protective cover.
Checking the operation of the new lock
The installation work is completed. Now you need to make sure that everything in the car is working properly. First we connect the battery. If the system is operating correctly, when the key is set to position “0”, all systems must be turned off. In position “I”, power is supplied to the engine management system, generator, headlights, warning lamps, washers and wipers, power windows and control devices.
In position “II”, voltage is supplied to the same systems, and in addition, the starter starts. If the lock is operating correctly, the locking rod of the anti-theft mechanism will extend and retract when the key is moved from position “0” (off) to position “I” and back.
As you can see, there is nothing supernatural - you can replace the ignition switch yourself, without turning to a car repair shop for help. The main thing is a little patience and knowledge, and you will master simple car repairs. And the “six” will delight you with its faithful service for a long time. Good luck on the roads!
Ignition switches for VAZ cars models 2101-07
When getting into a car, any driver turns the key in the ignition to start the engine. This simple action ensures that the starter receives voltage from the power source, as a result of which the engine crankshaft begins to turn and the engine starts. If a breakdown occurs with the ignition switch, further operation of the vehicle becomes impossible. However, many problems can be fixed with your own hands.
Ignition switch VAZ 2106
At first it may seem that the ignition switch of the VAZ 2106 is an insignificant detail. However, if you look at it, the mechanism is an integral part in any car, since it starts the engine and powers the electrical network. In addition to supplying voltage to the starter, electricity from the lock is supplied to devices that allow you to control certain parameters of the car, etc. When the vehicle is parked, the device de-energizes systems and devices.
Purpose and design
If we describe the purpose of the ignition switch in simple words, then this mechanism prevents the battery from being discharged through the on-board network and provides voltage only when necessary, i.e. during operation of the car.
The main elements of the ignition switch are: 1. - locking rod; 2 - body; 3 - roller; 4 - contact disk; 5 - contact sleeve; 6 - block
The ignition switch on the VAZ Six consists of the following elements:
- locking rod;
- frame;
- roller;
- contact disk;
- contact sleeve;
- block.
There are many wires connected to the lock mechanism. They are supplied from the battery and connect everything installed in the car into a single electrical circuit. When the key is turned, a circuit is closed from the “-” terminal of the power source to the ignition coil. The current passes through the wires to the ignition switch, and then is supplied to the coil and returns back to the positive terminal of the battery. When current flows through the coil, a voltage is generated in it, which is necessary to create a spark at the spark plugs. As a result, when the key closes the ignition circuit contacts, the engine starts.
The ignition switch is connected to the electrical circuit using wires with connectors at the ends. If the wires are connected to the mechanism using a chip (large round connector), then there should be no problems with the connection.
If the wires are connected separately, you must adhere to the following connection sequence:
- pin 15 - blue with a black stripe (ignition, interior heating and other devices);
- pin 30 - pink wire;
- pin 30/1 - brown;
- pin 50 - red (starter);
- INT - black (dimensions and headlights).
Below is the electrical diagram for connecting the lock:
Description
The ignition switch of the VAZ 2106 is made in the shape of a cylinder and consists of an electrical (contacts) and a mechanical (core) part. The mechanism also has a protrusion for fixing the steering wheel. On one side of the device there is a recess for the key, on the other there are contacts for connecting electrical wires. The two parts of the lock are connected to each other by means of a leash.
The ignition switch provides not only rotation of the contact group rotation mechanism, but also locks the steering wheel when the key is removed from the lock. Locking is possible due to a special rod, which, when turning the key to the right, partially enters the device body. When the key rotates counterclockwise, the element extends, and when it is removed, the part enters a special hole in the steering column. The locking mechanism is accompanied by a loud click when the key is removed.
"The lock
Since each key has its own tooth shape, this is an additional measure of protection against theft. Therefore, if you try to start the engine with another key, it will not be possible.
contact Group
The contacts of the VAZ 2106 ignition switch have the form of a washer with leads for connecting electrical wiring. On the inside of the washer there are conductive contacts of these terminals, as well as a movable element that rotates under the influence of the lock mechanism. When the position of this element changes, certain contacts are closed, thereby providing power to the terminals of the product in question, connected to the closed coins.
How does it work
The ignition switch of the “six” is located in the car interior to the left of the steering column and is hidden by decorative elements. On the driver's side, the mechanism has a key hole. There are several marks on the front surface of the lock - 0, I, II and III. Each of them has its own purpose.
The “0” mark is a position that ensures that all devices powered by the ignition switch are turned off; the key can also be removed in this position.
Electrical devices such as a brake light, a cigarette lighter, or interior lighting operate regardless of the position of the key in the lock, since they are constantly supplied with battery power.
Mark I - in this position, power is supplied to the on-board network. Voltage is supplied to the headlights, dashboard, and ignition system. In this case, the key is fixed and there is no need to hold it.
Mark II - in this position of the lock, voltage from the battery begins to flow to the starter to start the power unit. In this case, there is no locking, so the driver holds the key until the engine starts. As soon as the engine starts running, the key is released and it takes position I.
Mark III - parking. In this position, all electrical devices connected to the on-board network are de-energized, and a latch is inserted into the hole in the steering wheel column, which prevents the theft of the vehicle.

Ignition switch problems
Problems are possible with both the mechanical and electrical parts of the device.
The key won't turn
One of the lock malfunctions is a problem with the key, when it turns tightly or does not turn at all. Quite often the situation ends with the key breaking, as a result of which part of it remains inside the mechanism. A solution to the problem of a jamming lock can be the use of a penetrating lubricant, for example, WD-40. But do not forget that this is just a temporary solution and the switch will still have to be replaced in the near future.

Devices do not function
If such a problem is observed when the key is turned in the lock, but the instruments on the dashboard do not show “signs of life,” this may indicate damage to the contacts of the mechanism, as a result of which they do not fit together tightly enough. The malfunction is solved by replacing the contact group or simply by cleaning the contacts with fine sandpaper. It is advisable to check how tightly the connectors fit on the contacts - they may need to be tightened with pliers.
The starter does not turn on
If there is a problem with the lock, problems with starting the starter may also occur. The reason is damage to the switch contacts or failure of the contact group. As a rule, the malfunction is typical for the contacts that supply power to the starter. The problem manifests itself as follows: the starter does not start or it takes several attempts to turn it on. To determine whether there is indeed a fault in the contacts, you can check the voltage at the terminals using a test lamp or multimeter.
If it is discovered that the contacts have become unusable, it is not necessary to completely change the lock - you can only replace the washer with the contacts.
Ignition switch repair
To carry out repair work or replace the lock, it must be removed from the car. Tools you will need:
- Phillips screwdriver;
- awl.
How to remove the lock
After preparing the tools, you can begin dismantling, which is performed in the following order:
- Remove the negative terminal from the battery.
- Remove the decorative linings of the steering column.
- To avoid confusion with the wires during reassembly, write down on a piece of paper or mark with a marker which wire should be connected where, and then remove the wires.
- Use a Phillips screwdriver to unscrew the lower fastener of the lock.
- Insert the key into the device and turn it to the “0” position, which will disable the steering wheel locking mechanism. Immediately, using a thin awl, press the latch, by means of which the switch is held in place.
- By pulling the key towards you, the lock is removed.

How to disassemble a lock
During the repair process, as a rule, the “larva” or contact group is changed. To remove the washer with contacts, you will need a minimum of tools: a screwdriver, a hammer and a tool. Disassembly consists of the following steps:
Getting to the core of the castle is somewhat more difficult:
Video: repairing the ignition switch on a “classic”
What kind of lock can I put?
On classic Zhiguli cars, ignition switches of the same design were installed, but it should be taken into account that cars produced before 1986 were equipped with locks with 7 pins, and then with 6. If you need to replace a lock or washer with contacts with 7 pins, and find they failed, you can simply buy the second option and connect two wires together (15/1+15/2), and then connect them to terminal 15.
Installing the "Start" button
Some VAZ 2106 owners install a button for ease of starting the engine. It is connected via the starter power circuit to the break in the red wire, which goes to pin 50 of the ignition switch. In this case, the engine starts as follows:
- The key is inserted into the lock.
- Turn it to position I.
- The starter is started by pressing the button.
- When the engine starts, the button is released.
To stop the power unit, you must turn the key counterclockwise. A slightly different option for connecting the button is also possible, so that with its help you can not only start the engine, but also turn it off. For these purposes you will need the following parts:
- headlight relay RS 711;
- starter relay 113.3747–10 or 90.3747–10.
According to the diagram, when the button is pressed, power is supplied to the headlight relay, and after the contacts are closed, to the starter. When starting the power unit, the button is released, thereby opening the contacts of the starter relay and breaking its power circuit. If you press the button again, the contacts of the switching device open, the ignition circuit is broken and engine operation stops. The second option for using the button is called “Start-Stop”.
Even a car owner who is encountering such a problem for the first time can replace or repair the ignition switch on a VAZ 2106. To carry out the work you will need a minimum of tools and following step-by-step instructions. The main thing is to connect the wiring to the lock in accordance with the diagram.
The ignition is necessary in order to start the car and lock the steering wheel. After prolonged use, this element or its group of contacts become unsuitable for further use, the car does not react in any way to turning the key, and the cylinder stops freely allowing the key into itself. Therefore, it becomes necessary to replace the lock in order to restore the functionality of the car.
- locking rod;
- body part;
- roller with contact disk;
- sleeve;
- protrusion on contacts;
- wide protrusion of the contact part.
The locking mechanism comes into contact with a large number of wires. They reach to the battery and connect automotive electrical appliances into a single chain. At the moment the key is turned, the electrical circuit is closed from the “negative” terminal of the battery, as determined by the connection diagram for the VAZ 2106 ignition switch that comes to the coil. If the key begins to turn poorly or jams, this means that the secret is broken. Experts recommend spraying VD-40 into the larva, but the effectiveness of this is low and rather short-lived.
Has the contact group burnt out, after which you have difficulty starting the starter? Change the ignition switch.
The procedure for connecting wires to the ignition switch
Let's consider all stages of work one by one. First, remove the casing from the top and bottom of the steering column. Now, using a marker or regular paint, we mark the wires connected to the rear lock, after which they can be carefully disconnected.
Using a cross-head screwdriver, unscrew a pair of screws located below and directly securing the locking device:
Now we insert the key and turn it to the zero position to disable the anti-theft device that blocks the steering. At the same time, use a thin awl or a screwdriver to press on the fixing element, with the help of which the lock is held in place:
After completing these steps, pull the key to remove the locking mechanism from the bracket:
To install a new lock, all operations should be performed in reverse order.
Wiring sequence
If you are lucky and have a special chip for connecting the lock, everything is simple. But if such an element is missing, then the wiring will have to be connected one by one. To do this, you need to take the terminal block of the inserted lock so that one double-type terminal is located on the right and stands vertically. The top of this terminal should have black wire attached to it.
Next, you should work in the direction of movement of the clock hand. The pink wire will be connected second, followed by blue, brown, and the whole thing will be completed by a red wire.
It should be noted that on the rear block of the lock near the terminals there are numbers, each of which corresponds to a specific wire.
Remember that the bottom area of the double view terminal must be left empty. So, the contacts are connected.
Checking the results of the work
Having finished installing the lock, you need to make sure that all elements in the car are working without interruption. We connect the battery. If operation is correct, the vehicle systems must be de-energized when the key is inserted into the zero position. In the first position, power begins to flow to the system that controls the internal combustion engine, generator unit, headlights, signals, washer and glass cleaner, lifts and control devices. After moving to the second sector, voltage is supplied to the systems listed above and the starter device is started. If the lock is installed and working correctly, the anti-theft locking rod extends and retracts when the key is switched from the “zero” position to the first position and back.
In a word, there are no difficulties in such work. All operations are performed with your own hands, without the help of car service specialists. Moreover, the price of an ignition switch for a VAZ 2106 ranges from twenty to thirty rubles, and you shouldn’t chase inexpensive fakes!
