Domestic cars suffer from minor defects and frequent breakdowns. The ignition system in this situation is no exception. Most car owners are accustomed to restoring their “tens” on their own, so many car owners fix any malfunctions of the VAZ-2110 ignition switch in a garage.

To correctly determine the breakdown, you need to properly diagnose it. In this case, sometimes you will need a multimeter set to ohmmeter mode.

Diagnostic measures

Checking the condition of electrical components and mechanisms can be effective only after disassembling the decor that hides the insides. Plastic elements are located around the steering column, capturing parts and components partially located on it.

After opening access to the electrical part, you will need an ohmmeter to test the operation of the unit and the absence of failures when supplying current from the battery. Checks are carried out in different key positions. This is due to the fact that for each position certain contact closures are provided.

It is important to know that the resistance at the contacts of a working system must be zero.

The driver can start the car independently even if the lock is faulty. A similar situation happens on the road, when it is still far from the garage or the nearest car service station. The launch method is described in the presented video.

Motorists need to know exactly the basic steps of all operations. We carry out dismantling work according to the following scheme:

First, we de-energize the on-board electrical network. To do this, simply disconnect the negative terminal from the battery. At the next stage, you will need to fold down the steering column switches, which poses some difficulties. The lock mounting bolts are structurally protected by car manufacturing engineers to minimize the possibility of theft. To screw them together you will have to use a chisel and a hammer. This is inconvenient in limited cabin space conditions. We turn the heads with a chisel, and carry out further screwing with pliers.
The removed assembly will show obvious damage or defects. The backlight often burns out. We tilt it away from the connector and remove it from the socket. We insert the new one into the vacated slot.
When the functionality of a unit is lost due to poor performance of its duties by the contact group, we repair it, for example, soldering contacts or completely replacing the unit. It is necessary to decide what to do based on economic feasibility, because the group is not so expensive that much attention should be paid to it. If you need to replace it, just use a flat-head screwdriver to press the lock to release the part for repair or replacement. Assembly or installation is carried out in the reverse order, using the latch.
When replacing the key controller switch, you will need a Phillips head screwdriver, with which we unscrew three bolts. Next, remove the axial rod and hold the latch. This will allow you to release the switch and install a new one in its place.
Installation operations must be carried out sequentially, returning each part to its place. Before starting work, you must insert the key into the well and turn it to the first position. This will unlock the steering wheel rotation and remove the mechanical anti-theft protection. The special pin will come out of its holding position. Only after it is completely hidden in the nest will it be possible to begin work.

After completing the work, we recommend testing for blocking. Only when performing the algorithm is it worth covering the steering wheel axis with plastic decor.

The VAZ 2110 ignition switch cannot be called a reliable part, especially when you compare its service life with the same devices on cars of foreign origin. Therefore, owners of the tenth - twelfth model, who use the car for a long time, sooner or later encounter problems with the lock and its repair. On the other hand, the element can be easily removed from the car and every skilled motorist can replace it. But first you should figure out whether the entire part needs to be replaced, since in most cases it can be repaired.

Reasons for replacing the ignition switch

There are 3 main reasons leading to breakdowns of this device:

mechanical wear as a result of long-term use;
problems with the electrical part of the lock;
damage due to attempted break-ins and car theft.

Reference. The first troubles associated with turning on the ignition and starting the engine may appear after three years of operation of the VAZ 2110-2112.

Appearance of the ignition switch VAZ 2110—2112

Not every one of the listed reasons leads to a complete replacement of the element; sometimes you can get by with “little loss” by changing one of its parts. To determine this issue, you need to diagnose the signs of a malfunction:

Contacts are burnt or oxidized. In this case, the mechanical part works, but the electrical part does not. The problem is solved by cleaning or replacing the contact group.
The key gets stuck in the slot, after starting the engine it is not thrown back and you have to turn it by hand. These are malfunctions of the core (larvae) and the ejection spring, which can be completely repaired.
Obvious mechanical failures of the locking tongue (the steering wheel is very difficult to rotate), jamming or cracks in the housing are a reason to replace the entire ignition switch.

In the event of a mechanical failure, the key may not turn or may not be released by the spring.

A separate issue is the loss of all keys by the owners. It can be solved in two ways - by replacing the entire device or the key turning mechanism - the cylinder. For obvious reasons, the second option will be cheaper, especially if you do the work yourself.

Reference. As practice shows, the mechanical insides of an element can be broken by an ignorant driver who has lost his keys and is trying to unlock the steering wheel in order to start the engine by shorting the wires. There is a more elegant way - to remove the lock, and only then connect the wires of certain colors, as described below.

Checking the lock contact group with a multimeter

A faulty contact group can be easily diagnosed if you have a multimeter or other device with a resistance measurement function in your household. To do this, you need to get to the connector located under the plastic frame of the steering column and disconnect it. Then use a multimeter to measure the resistance between all contacts in the block, turning the key to different positions. Depending on the result, the following conclusions are drawn:

the device shows infinity - the contact group is out of order and needs to be replaced;
some resistance value indicates burnt or oxidized contacts, try to clean them;
zero readings on the device indicate that the electrical part is fully operational.

VAZ 2110 ignition switch diagram

Important! You need to measure the resistance in the block whose wires come from the ignition switch (male connector), do not confuse it with other contacts connected to the car’s on-board network.

Changing the ignition switch of a VAZ 2110 step by step

The hood of the car is opened and the negative terminal is removed from the battery.
The lower part of the cover on the steering column opens. The photo shows the progress of work with the VAZ 2109 lock, but these locks are structurally similar to the tenth model. The difference is the electrical circuit of the contact group, the replacement of which will be discussed below.

The protective cover has been removed from the bottom of the steering column

Carefully, using a chisel, loosen the fastening bolts of the lock (these are bolts with break-off heads).

The tension on the breakaway bolts is released using a chisel or a powerful screwdriver.

The ignition key is installed in the lock and then turned to the operating position “I”. After this, the latch that blocks the steering shaft is in the lock.

Now the bolts are unscrewed and the faulty lock is removed (if problems arise with unscrewing, the bolt heads are carefully cut off with a chisel).

A new lock is placed in its place, secured with a bracket in the desired position, and then secured with new bolts.

After installing the new bolt, the operation of the steering shaft locking mechanism is checked. To do this, the steering wheel is turned a full turn until the latch engages. If the latch does not operate, the fastening bolts on the lock are loosened and it moves up or down so that the latch fits exactly into the groove of the steering shaft when the steering wheel is turned completely.

After adjusting the latch and installing the lock in the correct position, its fastening bolts are tightly tightened with a 10mm wrench, and the tightening is carried out until the tear-off heads of the fastening bolts break.

Contacts are connected to the lock, the lower part of the steering column protective cover is installed in place.

Instructions for removing the element

For disassembly you need to prepare a simple set of tools:

10 mm head and ratchet drive;
Phillips screwdriver;
narrow chisel (width 5-8 mm);
hammer;
round nose pliers with tapered, curved ends.

Ignition switch replacement tool

To successfully install a new or repaired lock in place, it is advisable to purchase 4 special fastening bolts with M6 threads with a head size of 10 mm and a length of 20 mm. Their feature is the heads that come off with a key at a certain tightening torque. After tearing off the heads, semicircular caps remain on the surface, which are much more difficult to unscrew for an untrained person. But you will have to do this during disassembly.

The battery must be disconnected before starting work.

Like any event related to tampering with the electrical part of the car, dismantling the ignition switch begins with disconnecting the negative terminal of the battery. Then proceed in this order:

Using a Phillips screwdriver, remove the screws holding the two halves of the plastic frame of the steering column together.
Lower the handle that fixes the position of the steering wheel during adjustment all the way down and remove the plastic panels. Disconnect the ignition switch block and carefully cut the tape connecting your bundle of wires to the common harness. In order not to cling to the steering column switch during operation, it can also be pulled out of the connector.
On the metal casing of the steering column you will see a lock mount consisting of two clamps. They are held together by 4 bolts with the heads torn off (visible on the left side). Pointing the chisel at the semicircular caps, use a hammer to loosen the tightening of these bolts one by one.
Using pliers and then your hands, unscrew all 4 bolts and remove the ignition switch.

Unscrewing the plastic steering column cover

Note. There are “dozens” in which not all the bolt heads are torn off during assembly. This simplifies the matter; the fasteners can be easily unscrewed with a 10 mm socket.

Bolts with intact heads can be unscrewed with a wrench

At the stage of disconnecting the connectors, it becomes possible to check the functionality of the contact group by measuring resistance, as described in the previous section. If you remove the lock due to the loss of the keys and want to move on, then after dismantling you need to do the following:

On the “mother” block, which remains hanging after the lock is turned off, find contacts with thick wires of purple and blue color (the latter with a black stripe).
Connect these terminals with any conductor, after which the ignition will turn on.
The thick red wire leads to the starter. To start, its contact must be temporarily connected to the installed jumper. When the engine starts, the red wire must be disconnected.

Order of Operations

It is worth immediately noting that independently replacing the ignition switch cylinder of VAZ 2110, 2111 and 2112 is problematic. This part is difficult to find on sale, and working with it requires special skills. An incorrectly performed operation will result in unstable operation of the ignition system. In this case, you need to purchase the assembly and change it completely:

Since there is work to be done on the on-board electrical system, you need to disconnect the battery; to do this, disconnect the negative terminal of the battery. In addition, it is rational to provide good lighting in the work area, so you will spend less time performing operations.
Now you need to lower the steering column all the way and remove the plastic casing, after unscrewing the screws.
Using a chisel, unscrew the bolts with cut heads and pull them out with pliers. Hammer blows should be directed clockwise.
Now you can remove the bracket and the lock itself from the steering column by disconnecting the electrical connector.
If the backlight lamp needs to be replaced, the contact is disconnected and its socket is removed with pliers. Installing a new device.
To replace the contact group of the ignition switch of a VAZ 2110, 2111 or 2112, the clamps are released.
If the microswitch stops working, unscrew the screws, remove the rod, and pull out the latch. We install a working device.
We replace the contact group of the ignition switch of VAZ 2110, 2111 or 2112.
Now the operations are performed in reverse order. We install the assembled unit on the steering shaft, clamp it with a strap and tighten it with bolts. They need to be screwed in all the way; for this you can use a 10mm spanner or a socket with a knob. IMG8
Without breaking off the heads from the fasteners, we begin to adjust the steering wheel: the key is located opposite the I icon, and the steering shaft is in the same position. If the shaft does not lock and the steering wheel continues to rotate freely, you need to find the correct location of the lock so that its latch engages the groove in the shaft.
Now you can break off the heads from the bolts.
Once again we test the functionality of the mechanism. If everything is in order, you can connect the contacts.
We connect the lock with the battery by replacing the negative terminal. And again we test the performance of the node. If the results are positive, the decorative plastic casing is mounted in its original place.

Failure of the lock may be due to normal oxidation of the contacts in the group. In this case, you only need to clean with fine sandpaper. This malfunction can be determined using a multimeter in ohmmeter mode. Each pair must be tested for short circuits.

Repair of the ignition switch for VAZ 2110, 2111 and 2112 can be seen in this video:

Replacing the contact group

In the event that, as a result of diagnostics, a malfunction of the contact group is detected, you will still have to remove the ignition switch, since it will not be possible to get to it in any other way. After removing the element, disassemble it using the following algorithm:

Disconnect the connectors with the backlight power wires.
Remove the decorative plastic cover by releasing the 4 latches. Work carefully because these clips are easy to break off, and buying a cover separately is quite a task. It is not advisable to change the entire lock because of it.
By bending the 2 clamps holding the contact group, remove it from the ignition switch.

The plastic cover can be removed using a screwdriver

Note. You will additionally need a small flat-head screwdriver as a tool to bend the latches.

The contact group is located immediately under the cover

First of all, examine the status of the contacts. If they have darkened (oxidized), then clean the current-carrying surfaces with fine sandpaper P1000. Then put the group in place and, without installing the lock, connect it to the vehicle's on-board electrical system to check its functionality. If unsuccessful, the part must be replaced. The same will have to be done if the contacts are burnt or the group does not work without any external signs of malfunction.

, is performed in case of its malfunction. Like any problem, breakdown is best avoided. To do this, you need to know what leads to it.

Often, the contact group is simply oxidized. Therefore, it is simply necessary to pull the connector off the lock once a year and treat it with a special lubricant. This will push aside problems with this important detail.

Most often, the contact group burns out. It happens that this happens due to a long service life. The average service life of an element is about 3 years. If failure occurs more often, you need to look for the reason. Such a breakdown occurs due to too high a load on a particular contact. First, we determine what is connected through this contact. After that, we look for our own improvements. The most common cause is too powerful speakers and fog lights. But, in fact, the problem can be anywhere. Check all modifications for excess power.

To check or change this part, you will have to remove the lock. Be sure to disconnect the battery before doing this work. You will be working with electrical equipment; an accidental short circuit will not benefit your car. The work is carried out in the following order:

Remove the cover from the steering column. To do this, you will need a Phillips screwdriver;

Disconnect the connector with wires from the ignition switch;

The next step is to remove the lock itself. Some difficulty arises here; for safety reasons, the manufacturer made the heads of the bolts securing the lock break off. Therefore, you can’t just unscrew them. To do this, take a thin chisel and, pushing it towards the unscrewing side, tear the bolts out of place. Then you can unscrew them using simple pliers;

Remove the mounting bracket and the lock itself from the steering column.

Now you can repair this part. Replacing the contact is done as follows:

Installation of a new larva

To replace the lock core due to mechanical failure, remove it from the vehicle as described above. Then follow this algorithm:

Insert the key into the slot and use a Phillips screwdriver to unscrew the 3 screws holding the 2 halves of the lock body together.
Separate the housing while holding it with the key facing up. If you hold the lock in a different position during disassembly and do not insert the key, the insides will spill out and you will not understand how to put them back together. In this case, the ball with springs may get lost.
Remove the locking mechanism, which consists of two spring-loaded parts, and pull out the spring itself.
After removing the key, carefully remove the core so that the ball with the spring (located on the side of the cylinder) is not lost.

To disassemble the case, you need to unscrew 3 screws

Before replacing, it is necessary to remove the return spring from the old cylinder, since it is not sold complete with a new core. The spring is inside the part on the back side in a cocked state; it must be installed in the same form on the new cylinder. Also, do not forget to remove the thin spring from the hole where the ball is inserted.

The locking mechanism tongue peeks out from the bottom of the case

Important point. Remember that if you replace the core because it is broken, the new key will no longer fit the door lock. There are 2 options: use two separate keys or simultaneously change the cylinder in the door. The last method becomes the only applicable one when all the keys are lost.

The larva must be pulled out so as not to lose the details

When installing the core, you need to move the spring for the ball into the hole and insert the part into the body. Then push the larva all the way, while simultaneously inserting the ball into the socket. After that, all that remains is to assemble the locking mechanism and tighten the housing with screws. When finished, check the operation of the ignition switch by turning the key to different positions.

The ejection spring from the old core needs to be moved to the new one

VAZ injector errors

Errors can relate to any part of the car:

Sensors Most often, temperature sensors suffer, as they can overheat too much;
Injectors. Mostly, problems are observed due to an open circuit, as a result of which they cannot light up in time. This leads to another problem - the spark has disappeared, so the engine does not start;
Engine. The most common mistake is overheating. Most often, due to increased oiliness, the spark plugs also overheat, so a spark does not appear. As a result, the engine does not emit any signs of life;
Valves. They can also be too dirty, which will cause them to close, so they will not pass the fuel-air mixture;
Fans. If they do not work correctly, the machine overheats.

How the larva changes - video

The video demonstrates how to disassemble the mechanical part of the ignition switch of a VAZ 2170 (Lada Priora), but in design it does not differ from the elements installed on VAZ 2110-2112 cars.

As a rule, there is no need to change the entire ignition switch, although car enthusiasts often resort to this option to save time. The operation will take the technician at the service station no more than 20 minutes. Replacing it yourself will require more time, but you will be able to replace only the broken part (cylinder or contact group), thereby saving personal funds.

If a problem comes

What if there is something wrong with the ignition switch? Is it impossible to turn the key without force, or is it even jammed? It’s clear that the lock cylinder is damaged, and you can’t go far in such a car. This can happen for various reasons: the larva was caught with a defect, or over time it simply accumulated dust and dirt. In this case, you can try replacing the larva.

A small fault can lead to big problems

If the key still turns, but the ignition system does not respond, then the contact group has clearly failed. Of course, you can replace it, but in this case you run the risk of purchasing a spare part that is not of very high quality. This will not get rid of the problem, but will only temporarily postpone its solution.

What if you simply lost your key and it was the only one you had? Or another, very unpleasant situation: an attempt was made to steal your car (God forbid, of course!), and the ignition switch was completely damaged.

Troubleshooting

Before tackling the question of how to change the ignition switch on a VAZ 2110, you need to find out the nature of the malfunctions. How to check the ignition switch of a VAZ 2110 is described in the instructions.

1-reserve; 2-minus backlight; 3-starter; 4-plus after the ignition switch; 5-reserve; 6-plus backlight; 7-constant plus; 8 is a constant plus.

1-5	On the VAZ 2110 it is used for the immobilizer. You can connect any device you wish.
1-6	Castle lighting.
INT	On the VAZ 2107, these are lighting, wipers, and washer - a constant plus.
50	Starter.
30/1	A constant plus.
15	A plus appears when the ignition switch is turned on.

Troubleshooting the ignition switch on a VAZ 2110 is carried out in the following steps:

The battery will be disconnected.
The casing is removed from the steering wheel shaft column. To do this, unscrew several screws.
The lock connector is removed from the back.
Using a multimeter, the voltages in the contact groups are checked. The installed key switches in different positions.
Voltage on pins 8 and 30 is present only when the key is in zero position.
In position 1, the servicing devices are turned on: turns, headlights and heated glass.
In position 2, voltage is supplied to devices related to engine operation.
In position 3, the starter is activated. The key then returns to its original position.

If there are interruptions during the verification process, then the ignition switch on the VAZ 2110 requires disassembly and repair.

Common mistakes during diagnostics

Most people, due to ignorance of the VAZ 2110 injector machine, make many mistakes in the process of identifying problems.

Let's look at some of them:

Many people make a common mistake: when they see that there is no spark, they want to check it for breaks. For this purpose, they place the wire close to the ground of the machine. But when performing such actions, the ignition module may break, so under no circumstances should you do this;
Another problem is checking the spark discharge. If you place spark plugs on the engine body, a large induction current may appear. This occurs even due to slight contact of the spark plug with the ground, as a result of which the controller can also be damaged. Therefore, it is necessary to use a spark gap that will not allow the distribution of ignition with the same supply of high voltage to two spark plugs at once.

Disassembly and replacement procedure

When the source of the malfunction is identified, the question immediately arises: how to disassemble the ignition switch on a VAZ 2110.

To do this, first it is removed. Since the preparatory work has already been done, the following actions remain:

The housing mounting bolts are unscrewed.
The lid made of plastic material is removed. The lock is removed.

Replacing the larva

Before changing the ignition switch on a VAZ, sometimes it is enough to replace the cylinder.

The process consists of several steps:

A small diameter pin holding the cylinder is removed from the side. The work is carried out using a thin screwdriver and a hammer.
The old larva is removed and the new one is installed.
To check, the steering wheel is turned and the reliability of the jamming is checked.
Sometimes the blocking is adjusted.

After replacing the used element, you need to know how to assemble the ignition switch of a VAZ 2110. This process occurs exactly in the reverse order.

Replacing the contact group

Knowing how to change the ignition switch on a VAZ 2110 with your own hands, this is not always necessary. Ingod the contact group fails, which, like the larva, changes.

Its replacement is carried out in the following order:

All contacts are numbered before they are disconnected.
Then they are disconnected.
2 latches are removed.
The old group is removed and a new one is installed in its place.
Then, in the reverse order, the assembly is assembled.

Complete lock replacement

Craftsmen who know how to change the ignition switch on a VAZ 2110 with their own hands have long realized that this process is much easier than replacing individual structural parts.

After disconnecting the battery, removing the steering casing and unscrewing the bolts, the plug is disconnected and the lock is removed. This completes the operation to remove the old node. A new product is installed in its place.

If you still have questions about how to change the ignition switch on a VAZ 2110 with your own hands, I recommend watching this video:

Repair of the ignition switch on a VAZ 2110 car

Having identified a malfunction that has arisen in the car’s ignition switch and if it is not possible to make repairs using soldering. Repair is carried out by directly replacing the faulty element. As mentioned earlier, this is usually the cylinder or contact group of the ignition switch.

To repair the ignition switch of a VAZ 2110 car, we will need the following tools.

replacing the lock cylinder, step-by-step instructions

The ignition switch cylinder on a VAZ 2110 car is replaced in case of direct damage, biting, etc. As a rule, such problems appear after long-term use of the car or in the event of an attempted theft.

And so, replacing the ignition switch cylinder on a VAZ 2110 car is carried out in the following sequence:

Remove the terminals from the battery (to de-energize the ignition switch);
Remove the casing from the steering column of the car;
Unscrew the ignition switch mounting bolts;
Pull out the ignition switch (to make it convenient to work);
Carefully pull out the pin from the side; it holds the ignition lock cylinder (the easiest way to pull it out is with a thin screwdriver and a small hammer);
Having pulled out the larva, we install a new one;
We check the functionality of the ignition switch;
Check the adjustment of the steering wheel lock when turning;
We adjust the blocking (if necessary);
Let's put everything in its place.

replacing the ignition switch contact group, step-by-step instructions

After diagnostics, if a malfunction is detected in the operation of the ignition switch contact group itself. You can only replace it. The contact group of the ignition switch, like the cylinder, is a replaceable part and is sold in car dealerships.

And so, replacing the contact group of the ignition switch on a VAZ 2110 car is carried out in the following sequence:

Remove the terminals from the battery (to de-energize the ignition switch);
Remove the casing from the steering column of the car;
We unscrew or knock down the ignition switch mounting bolts with a hammer and chisel;
Remove the plastic cover from the ignition switch;
We disconnect all contacts (before disconnecting it is recommended to number them to avoid confusion in the future);
Using a screwdriver, unfasten the two latches;
We take out the contact group;
Installing a new contact group;
We put everything back together in reverse order.

Choosing a new lock

It’s not enough to know how to change the ignition switch on a VAZ 2110 with your own hands; you also need to make the right choice of a new product. Existing fake options that do not survive for a long time.

During the selection process, attention is paid to the following criteria:

impossibility of tearing off the characteristic holographic sticker;
the correct shape of the casting of the body;
the key must enter without visible resistance;
high density packaging;
the protruding tongue is distinguished by a light shade.

Existing articles of ignition switches for the VAZ 2110, which are distinguished by their reliability, for example: lock VAZ 2110-3704005-30.

Dismantling

If previous activities have shown that intervention in the design of the ignition switch is required, work in any case will begin with dismantling the device.

We have special step-by-step instructions for this.

To begin, disconnect the negative terminal from the battery of your VAZ 2110. This way you will ensure your safety and the safety of all wiring. You know what the consequences of a short circuit are.
Next, remove the casing on the steering column. This is how you gain access to the castle.
If you feel that the rotary switches will interfere with your work, it is better to remove them immediately. The work does not last for a couple of minutes, so all irritants should be put aside.
Armed with a chisel and hammer, unscrew the mounting bolts with round heads. Don't get confused, they are the only ones there. Try to perform this operation as carefully as possible so as not to knock off the bolt head.
Now take the pliers and remove the bolts.
Insert the key into the ignition and turn it to position zero. This will disable the anti-theft system.
Next in line is the bracket that held the previously removed bolts and the ignition switch itself.
Mark the contact wires using different colored markers. Otherwise, you can easily mix them up during reassembly.
Often it is not necessary to completely replace the lock, but only partial repairs. For example, change the backlight bulb, or fix a microswitch problem.
Disconnect the connectors that used to operate the ignition switch.
To replace the backlight bulb, disconnect the corresponding connectors, and then use pliers to remove the bulb.
To replace the contacts, use a screwdriver to press out the special latches.
Using a shaped screwdriver, unscrew three screws, after which you can remove the rod.
Use a regular flathead screwdriver to pry out the clips and remove the microswitch.
Next, new ones are inserted in place of the dismantled elements.

Checking status

Installation

Now that all preliminary repair work has been carried out, there are two options:

Install a completely new ignition switch with wires and contacts, since the old one is unsuitable for further use;
Return the old lock to its place, since the repairs have borne fruit.

Before installation, be sure to purchase special bolts equipped with break-away heads. They are designed to prevent your vehicle from being stolen.

Regardless of the option, the lock installation sequence is identical.

Insert the key into the ignition, then turn it to position one.
Secure the bracket to the steering column, and then replace the mounting bolts.
Remove the key from the lock and check that the shaft lock works properly. If it's a new lock, there shouldn't be any problems. If we are talking about a refurbished old one, troubles may arise, since in reality it is better not to skimp and immediately replace the spare parts with a device of good quality.
If everything works as it should, then you can complete the installation of the lock by tightening special bolts that are equipped with tear-off heads.

Buy only high-quality locks from trusted suppliers. Today there is an impressive number of fakes on the market, which use materials and components of dubious quality. Because of them, you can be seriously injured and even lose your car.

At the moment, the cost of a new ignition switch is about 20-25 dollars. These are small expenses, but sometimes simply necessary. Whether to do the repairs yourself or trust the car to a service station is a personal choice for everyone.

screwdriver;
hammer, chisel.

The actions are as follows.

On Kalina, when removing the column casing, you need to pull out the steering wheel adjustment knob.
You also need to remove the sealing ring of the cage.
Next you need to disconnect the immobilizer block and the assembly block.
Again, use a chisel to unscrew the mounting bolts of the holder. There are four of them here.
We remove the defective element along with the bracket.
We install the new unit, moving backwards step by step. We again use bolts with a break-off head.

If you wish, you can study all this technology in a video called “how to change the ignition switch on Kalina.” Interestingly, the video on the topic “how to change the lock on a Gazelle” will look very similar, since the processes are similar.

Now we will also discuss the procedure that reveals how to change a faulty ignition switch on a Niva. This process is carried out by analogy with the classic VAZ. They take a screwdriver.

They do the following.

Unfasten and remove the steering column trim.
Disconnect the wires, remembering their position.
Unscrew the two fasteners.
By inserting the key, fixing it at the “0” mark, and also pushing the latch onto the side with a screwdriver, remove the clip.
The new unit is installed in the reverse order.

A couple of notes and the price of reinstallation

Sometimes it happens that a car owner changes the ignition switch, but the car does not start. Most likely, such a nuisance occurs due to incorrect connection of the wires, especially in the classic VAZ.

However, if the car enthusiast still does not rely on his own strength, he can carry out the above operation at a car service center. How much it will cost is indicated in the following table.

City	Price
Moscow	1000 rub.
St. Petersburg	1000 rub.
Ekaterinburg	900 rub.
Samara	800 rub.
Krasnodar	900 rub.

Average data is shown here. In reality, the price will differ; it greatly depends on the level of complexity of the work and the make of the car.

The ignition switch is a small device, but very important. With its help, we give a signal to our car - we start or stop the engine, and also turn on the power supply to the devices. In addition to starting the engine, the ignition switch has another important function - steering lock, that is, in fact, it is an anti-theft device. Take out the key, turn the steering wheel a little, and you will see that the steering shaft will instantly lock. Accordingly, this device must work flawlessly, otherwise each of us may find ourselves in a situation where it is necessary to replace the ignition switch. This element of the automotive system is very important.
