In fact, the ignition switch is a regular switch that closes or opens certain groups of contacts. VAZ 2109 - removing and replacing the clutch cable |, A faulty ignition switch will increase the already huge likelihood of your car being stolen, and will also create huge problems for you and, as a rule, at the most inopportune moment for this.

Typically, replacing the VAZ 2108 ignition switch is carried out in the following cases:

When they tried to steal the car, the ignition was damaged;
If the car owner loses the key;
When the contact group fails.

The car may not start due to terrible contact. It’s easy to check; all you need is an ohmmeter and a couple of minutes of time.

Replacing the lock cylinder or contact group

The need to completely replace the VAZ 2108 ignition switch may only arise in the event of the above problems, but if the cause of the malfunction is one of its parts, then it makes sense to carry out a partial repair of the ignition switch. VAZ 2109 engine injector: 21083, 21093, 21099. Citroen engine malfunction. Belt replacement. For example, often the ignition key is turned incorrectly in the keyhole; The malfunction can be eliminated by replacing the ignition switch cylinder.

Scheme of VAZ and car ignition switch

The ignition switch cylinder of the VAZ 2109, despite its small size and completely inconspicuous location, together with the lock, plays the main role in the operation of the vehicle systems. Therefore, the failure of such a small unit can completely paralyze the operation of the entire car.

The ignition switch is used to turn on the power to the entire ignition and engine starting system, windshield wipers, reversing lights, turn indicators, and in some modifications even the radio and headlights. In addition, on some cars the ignition switch is additionally equipped with an anti-theft device that blocks the steering wheel from turning.

On a VAZ 2109, replacing the lock cylinder is very simple. It is only important to study the execution sequence and choose a tool.

The main purpose of the lock was initially to protect the car from theft, however:

Today, 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 protection from the castle used to justify itself, but today it is “so-so”
Advanced car thieves, equipped with modern technologies and devices, are able to hack the electronic 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 domestic 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 appearance of a malfunction in the ignition switch increases the likelihood of vehicle theft several times, in addition, it creates great trouble for you and, according to the law of meanness, at a completely inappropriate moment for this
The design 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 required sequence
Already now, switches that have the same design and order of contact closure are successfully used on all domestic cars

Reasons for replacement

As a rule, replacement of VAZ 2109 lock cylinders is carried out in the following cases:

When they tried to steal a car and the lock cylinder was damaged in the process
If the owner of the car has lost his keys
Breakage of the larva during operation

The car engine may not start due to poor contact. It is not at all difficult to check this; to do this, it is enough to have an ohmmeter on hand, or a multitester with an ohmmeter function and five minutes of time:

Disconnect the “-” terminal from the battery
Remove the lower casing from the steering column

Removed the casing and opened the contacts

Disconnect the contacts and check the resistance with an ohmmeter
Serviceable contacts should have minimal (zero) resistance
Otherwise, you need to replace either the contact group or the entire lock

We measure the contact resistance using an ohmmeter

Replacing the VAZ 2109 lock cylinders requires the following tools:

New cylinder complete with keys
Thin clock screwdriver
Phillips screwdriver
Fine drill
Chisels
Hammer
Pliers

In the event of any breakdown, it is not necessary to replace the entire lock; if the cause of the malfunction lies in replaceable parts, then a partial repair of the lock is performed and replacing the lock cylinders on the VAZ 2109 makes sense when the key stops rotating freely in the keyhole. Another option for partial repair is to replace the contact group; for this, a minimum of tools and a little understanding of the device are enough. Our instructions 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 opens
The lock cylinder can, in principle, be removed at this stage
Therefore, we pull out the side pin that holds it in the lock
This can be easily done with a thin screwdriver (clockwise) while tapping it with a small hammer
If the pin cannot be pulled out in this way, then try to drill out the cylinder carefully using a thin drill
If it is more convenient for you to remove it first, remove the ignition switch before proceeding to replace the cylinder, to do this you need to unscrew the bolts securing the ignition switch to the steering column
This must be done using a hammer and chisel, as these bolts have sheared heads.
Use a chisel to loosen them slightly, and then unscrew them with pliers, as in the photo below

Loosen the bolts securing the lock to the steering column

Now we remove the bracket and the lock itself from the column, be sure to disconnect its electrical 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 a new 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 steering shaft
When the mechanism does not work when turning the steering wheel fully, you need to adjust the location of the lock on the steering column
Only after completing the adjustment of the location and checking the functionality of our locking mechanism, you can tighten the bolts until the heads come off completely, use a “10” spanner for this purpose

Exploded view of the lock
From a cost point of view, replacing one contact group is the least 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 common nuisance associated with mixing up contacts, it is recommended to number them (or otherwise mark them) before disconnecting them.
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 remove it
It’s important not to forget to put it back in place later.
Then everything is assembled back and screwed to the steering column

That's all, all that remains is to finish watching the video and calmly change any part of the lock.

Ignition switch VAZ 2108-09 (reason for malfunction)

We will tell you how quickly you can change the ignition switch. If possible, without even taking it off

Before starting work, you must turn off the ignition switch of the VAZ 2108; to do this, as always, remove the negative terminal from the battery. Replacing the timing belt VAZ 2109 1.5 liter 8 valves with photos and videos. Next you need to remove the steering column cover. Then, to make cylinder replacement easier, remove the ignition switch. Replace the faulty lock cylinder with a working one and reassemble everything in reverse order. Replacing the front wheel bearing of a VAZ 2109 (21099.... Set the ignition switch to position.

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 contact group:

1) First, on the removed ignition switch, use a screwdriver to unscrew the screw that secures the ignition switch cover.

2) Then use a screwdriver to press out the two plastic latches securing the lock cover.

3) Then remove the cover.

4) And finally, remove the contact group from the ignition switch.

Note! Installation of the contact group is carried out in the reverse order!

Important! Not on all cars of the Samara family the ignition switch is attached to the steering column with four bolts; on some cars it is attached only with two bolts and on top it is secured with a hook indicated by a red arrow!

Additional video material: Below we have prepared a video related to replacing the ignition switch on cars of the Samara family.

Replacing the contact group of the ignition switch VAZ 2108

From a financial point of view, replacing a contact group is the least expensive. Basically, as in the previous case with the lock cylinder, you will need to remove the lock and the cover. Replacing the ignition switch on a VAZ 2101-VAZ 2107. To avoid problems associated with confusing contacts, I recommend numbering or somehow marking the wires into which it was connected, this will save time and nerves. Some lock models have a retaining ring in the contact group; you will need an awl to remove it. When finished, be sure to reinstall the safety ring.

Self-replacement of the ignition switch of a VAZ 2108

For this work, you need to use special bolts with break-away heads; I do not recommend using M6 twenty mm instead, since in this case it will be easier not only for you, but also for car thieves to remove the ignition key.
Using a chisel, you need to unscrew or knock down the bolts.

Before replacing the lock, turn the key to the “I” position so that the latch that locks the steering shaft mechanism can enter the lock body.
Now that nothing is in the way, you can begin installing the new ignition switch.
Install it onto the steering column, secure it with the bracket, then tighten the frame with new mounting bolts.
After installation, do not forget to make sure that the steering shaft locking mechanism is working properly; if the mechanism does not work, after one full turn of the steering wheel, you need to adjust the position of the ignition switch on the steering column.
After completing the position adjustment and checking the operation of the locking mechanism, tighten the bolts until the heads are completely disconnected, to do this, use a “10” wrench.

We start the engine, make sure that it is working properly and there are no problems with starting, if everything is in order, we conclude that replacing the VAZ 2108 ignition switch with your own hands was a success!

Ignition replacement and check

To replace the ignition switch, you need to perform all the steps in a certain sequence:

Before replacing, you must remove the negative terminal from the battery.
Remove the steering column cover and the two switches located under the steering wheel.
After this, you need to insert the key into the ignition switch and set it to the zero position. This is necessary for the anti-theft device to be disabled.
Next, unscrew the 4 bolts that hold the ignition switch. If bolts with sheared heads are installed, knock them down using a hammer and chisel.
After unscrewing (knocking down) the bolts, remove them from the holes using pliers.
On the left side, remove the bracket, and then on the right side, remove the ignition switch.
Then disconnect the wire block from the electrical connector.
Get under the dashboard and disconnect the ignition switch connectors from the relay.

Installing a new lock must be done step by step in reverse order.

To check the contacts on the wire block, use an ohmmeter. The device must display zero. If his readings are different, change the contact group.

To change a contact group, you need to do the following:

Using a screwdriver, unscrew the screw that secures the cover.
Bend back the plastic latches that hold the cover in place, then remove it.
Remove the contact group.

The contact group is also installed in the reverse order.

Not in all cases it will be possible to find four bolts on the steering column on a VAZ-2109. On some models it can be secured with two bolts and a hook.

Ignition switch VAZ 2109 faults

The ignition switch of the VAZ 2109 is a very important and at the same time very capricious mechanism of the car. And in today’s article we will try to highlight its importance and capriciousness, that is, malfunction. The ignition switch serves to supply voltage to electrical circuits depending on the position of the key. The castle consists of 2 parts. These are the mechanical and electrical parts.

As already written, in our nine the power switch is a very important mechanism. Almost the entire electrical part of the car passes through it. Only a few devices can operate without an ignition switch, namely:

1. Side lights.

2. Emergency alarm.

3. Interior lighting.

5. Illuminated license plate.

This is necessary so that when stopping on the highway or in the city in an unlit place, we do not need to turn on the ignition to be noticed.

VAZ 2109 ignition switch diagram.

Lighting units on the VAZ 2109 can be of different designs. There are 2 samples, this is new and old. The new one differs from the old one only in the absence of a relay, a shortened key and three key positions instead of four.

1. Ignition relay

2. Ignition switch connector

3. Power switch.

The ignition switch of the VAZ 2109 is faulty.

The most common problem with the lock when turned on is that it trips and jams. With such signs, it is necessary to immediately change the entire ignition switch, because if it jams, you can simply burn the starter, and then the repair will cost you the price of the starter. Another common problem is contact group failure. In this case, several devices fail at the same time. For example, the low beam headlights, heater, cigarette lighter, and rear window heater immediately stopped working. I replaced the contact group with a new one, everything worked immediately.

Design and troubleshooting of the ignition switch of the VAZ 2109

One of the key components of the VAZ 2109 car is the ignition switch. In the electrical circuit of a machine, it is used as a switching unit to supply voltage to the necessary power circuits. If this does not happen due to a malfunction of the switch, it is possible that individual groups of consumers or the car as a whole can be turned off - it simply does not start.

Typical faults

VAZ 2109 ignition switch

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”;

VAZ 2109 ignition switch malfunction

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.

Design and principle of operation of the lock assembly

It is possible to install 2 standard modifications of the lock on the VAZ 2109 car. The old one has catalog number 21080-3704005-60. It features four (long) key positions and also contains an ignition relay. The new assembly with catalog number 21080-3704005-30 has only three key positions and does not contain a relay.

To connect all the cables to the lock of the VAZ 2109 car, a contact group is used. Each of the key positions has its own setting, which means there is a group of consumers.

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 thread is closed with brown, and the pink thread with black and blue. In this case, several groups of contacts are formed. For example, "30 INT" activates the external power circuit including high beam, lighting, instrument panel lighting. Contacts “30/1” and “15/1” supply voltage to the turn signal lamps, reverse gear lamps, elements of the ignition system, etc. The “30/1”, “15/2” pair powers the low/high beam headlights, fog lights, washing machine, fans.

The ignition relay installed in the previous step continues to operate. The main one is a pair of contacts “30”, “50”, which supplies voltage to the starter. In parallel with this, chains of contact connections “30/1”, “15/1”, as well as “30/1”, “15/2” should be formed. The utilities 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).

It is used to supply voltage to the parking system components ("30/1 R") and the parking/instrument lights ("30 INT"). The black wire, together with the brown and pink wires, forms a closed circuit.

The lock and its circuitry perform two functions: electrical and mechanical. The essence of the first is to close certain groups of contacts based on the location of the key. From a mechanical point of view, when the ignition is turned off, the steering wheel is locked, making rotation impossible. That is, the second function is protective.

Possible malfunctions and ways to eliminate them

The nature of the malfunction of the locking unit on a VAZ 2109 car can also be electrical or mechanical.

The first group includes violations of the integrity of electrical circuits in the switch at a certain key position. If there is no contact, the connected consumers may not work or the car may not start at all. If there is contact, but the wrong sections of the circuit are closed as expected, this is fraught with a short circuit and thermal damage to the lock. It will begin to melt and a characteristic smell will appear. Depending on the severity of the disaster, the contact group will most likely need to be replaced.

From a mechanical point of view, the core/larva can get stuck in any position. In this case, it will be physically impossible to turn the key in the lock. The only correct repair option is to replace the entire assembly.

To diagnose faults in electrical circuits, you need to stock up on the following tools.

Multimeter or tester. If it is not available, as an option you can use a control lamp operating on a voltage of 12 V.
A set of screwdrivers, keys for disassembling the lock. Since the only option for resolving mechanical problems is to replace failed parts, they will come in handy in this case.

Before starting diagnostics, it will be necessary to disconnect the terminal block and make all contacts ring in the sequence that corresponds to each of the key positions. For clarity, you should have an electrical diagram of the unit at hand. If the circuit is closed, the meter will show a resistance reading.

Replacing the lock should begin with de-energizing. To do this, you will need to loosen the locking nut and remove the negative battery terminal. After this, the protective and decorative casing and the rotary washers are removed. The steering column lock is secured with four screws or two screws and a latch. Removal may be difficult due to screws. In this case, they will need to be cut or drilled, doing everything with extreme caution. The terminal block is disconnected and the disassembly process is complete.

Assembling a new lock is similar, but in reverse order.

Purpose and device

The main purpose of the lock was initially to protect the car from theft, however:

Today, 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 protection from the castle used to justify itself, but today it is “so-so”
Advanced car thieves, equipped with modern technologies and devices, are able to hack the electronic 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 domestic 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 appearance of a malfunction in the ignition switch increases the likelihood of vehicle theft several times, in addition, it creates great trouble for you and, according to the law of meanness, at a completely inappropriate moment for this
The design 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 required sequence
Already now, switches that have the same design and order of contact closure are successfully used on all domestic cars

Reasons for replacement

As a rule, replacement of VAZ 2109 lock cylinders is carried out in the following cases:

When they tried to steal a car and the lock cylinder was damaged in the process
If the owner of the car has lost his keys
Breakage of the larva during operation

The car engine may not start due to poor contact. It’s not at all difficult to check this; to do this, it’s enough to have an ohmmeter on hand, or a multitester with an ohmmeter function and five minutes of time:

Disconnect the “-” terminal from the battery
Remove the lower casing from the steering column

Removed the casing and opened the contacts

Disconnect the contacts and check the resistance with an ohmmeter
