How to remove the ignition switch on a VAZ 2112 injector 16 valves

Malfunctions

The ignition switch on VAZ 2110 and 2112 is replaced if this part is faulty. There are 2 groups of breakdowns of this element:

• Mechanical faults
  . The most common malfunction is the failure of the larva. The keys are made of soft metal, which makes them not very reliable and often leads to them breaking off. Steering wheel lock. Key stuck in the on position;
• Contact group wear
  .

Regardless of the nature of the breakdown, you will still have to remove the lock. Only if the locking tongue is jammed, this will be more difficult. A contact group or problematic larva can be completely corrected.

Advice from professionals

• Every year, replacing the cylinder and contact group of the ignition switch becomes less and less relevant. This happens for the reason that it is much safer, more convenient and faster to completely replace the ignition switch.
• Despite the apparent prostate replacement of the contact group or cylinder of the ignition switch. The process is quite labor-intensive, and if you are not confident in your abilities, it is better not to undertake it.
• Often, when the ignition lock cylinder is biting or jamming, regular lubrication helps. Graphite grease is best suited for lubricating the ignition lock cylinder.
• To avoid malfunctions in the ignition switch after its immediate replacement. Only the original ignition switch must be installed. This is a guarantee that it will serve you for a long time.

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.

Replacement

To remove the ignition switch you will need the following tools:

• Phillips and slotted screwdriver;
• Chisel. You will need something thin and sharp;
• Hammer;
• Pliers;
• Key for 10.

This is quite enough. Sometimes, something else may be required. But this is quite rare.

Before work, remove the terminal from the battery. This will avoid short circuit. After which you can begin dismantling work:

• Remove the steering wheel covers. The manufacturer also recommends removing the steering wheel. This is not required, but is advisable;
• The steering column turn switch is removed. To do this, the latches securing it are released and the switch is removed from the column;
• Disconnect the wiring block;
• The bolts holding the lock to the steering column are quite tricky. Their caps break off when twisted. Therefore, it will not be possible to unscrew this fastener with a regular key. To do this, take a chisel and set it at a certain angle. Then, with gentle blows, we tear the bolt out of place, and then you can unscrew it using pliers. The same applies to other bolts, there are 4 in total;
• After this, you can remove the old lock;
• When installing the lock, please note that bolts are supplied with it. According to the manufacturer's idea, their heads break off when tightened to a certain point. Instead, you can use M6 bolts of suitable length. This work has no other special features.

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:

1. Using a Phillips screwdriver, remove the screws holding the two halves of the plastic frame of the steering column together.
2. 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.
3. 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.
4. 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:

1. 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).
2. Connect these terminals with any conductor, after which the ignition will turn on.
3. 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.

This is how jumpers are inserted into the block to start the engine without a key.

Advice. It is more convenient to look at the colors of the conductors on the harness of the removed device, and then find them on the “mother”.

After unscrewing the fasteners and disconnecting the wires, the lock can be easily removed from the car

Assembly is carried out in the reverse order, but taking into account the following precautions:

• do not tighten the fastening bolts until you have accurately aligned the position of the lock on the casing so that the facing plastic panel fits smoothly into place;
• before final tightening the bolts, make sure that the lock snaps into place when turning the steering wheel, otherwise adjust the position of the lock;
• The tightening torque should be such that the heads of the new bolts come off and the round heads remain.

When installing and tightening the bolts, their heads should come off

If you think that special fasteners are not an obstacle for car thieves, then you can screw in regular bolts with M6 threads and carefully tighten them.

Repair

The complete lock is not very expensive, but most of its problems can be fixed. Just replace the failed parts. Repair work will not take you much time and effort.

To replace the contact group, you should press the latches, after which this part of the filling will simply fall out of the case. A new group is being installed in its place. It is impossible to mix up the sides for installation. Otherwise, the part simply will not fit into place. To prevent problems with the contact group, it is necessary to lubricate the terminals with a special lubricant every few months. This will reduce the formation of oxides.

If the larva is faulty, it must be replaced. To do this, remove the protective plate from the front side of the part. This can be done using a slotted screwdriver. After which, the larva is pryed off with the same screwdriver and removed. All that remains is to put the new one in place. To extend the life of this part, it is recommended to periodically inject it with penetrating lubricant.

Do we replace the entire lock, or just the contact group?

The issue is purely economic in nature. It is clear that replacing the complete lock will cost three times more , so before replacing the ignition switch completely, it is worth understanding the causes of the malfunction. It is possible that it will be enough to simply replace the contact group if everything is in order with the cylinder and the mechanical part of the lock.

Appearance of the contact group

A startup problem may occur when the contacts on the contact group are burnt or oxidized.

Ideally, it is better to replace oxidized, and even more so burnt, contacts, however, they can simply be cleaned with very fine sandpaper. Diagnostics of the contact group is carried out using a multimeter in ohmmeter mode . Each pair of contacts on the terminal block is checked using the probes of a multimeter - we turn the key in the ignition switch and test each pair of contacts on the terminal block for a short circuit; if the multimeter shows zero resistance, everything is in order with the contacts.

We check each pair of contacts on the terminal block

There may be problems with the mechanical part of the lock, and in this case, experts do not recommend changing the cylinder yourself - firstly, it is quite difficult to find it on sale, and secondly, replacing the cylinder may be carried out incorrectly and, as a result, the entire lock will not work incorrect. In this case, it is more rational to buy a complete lock and replace it completely. It's more reliable and safer. Good luck to everyone and good travels!

Ignition switch malfunctions

The ignition key on a VAZ 2110 should be replaced if its operation cannot be restored in any way or the key is broken/lost. In other cases, they are usually repaired.

There are two groups of main breakdowns:

• The mechanics are faulty. The most common problem. larva breakdown. The keys are made of soft metal, so they are unreliable and often break. There is also a problem with the steering wheel locking, or the key may simply jam when in the on position.
• Contact group wear. No matter what damage you have, you will still have to the lock If the locking tongue is stuck, you will have to work hard to correct the situation. The contact group or larva is completely repaired.

There are many instructions and methods for checking the ignition on a VAZ 2110, some of which will be discussed.

Detailed instructions for checking the ignition switch malfunction:

READ How to set the ignition on the Mtz 80 launcher

The ignition switch in a VAZ 2110 car, like on any other, is designed to switch electrical circuits and turn on the starter. Therefore, if it fails, you will no longer be able to start the car.

It should be noted that the ignition switch. This is a motor start/stop tool, it can open or close certain groups of contacts, so if the lock is broken the motor will not be activated. So if you have a problem with this, you will definitely need a wiring diagram and a wiring diagram for the lock on the VAZ 2110 for checking and repair.

The result of the work done

From all of the above, we can conclude that all these operations are quite simple and, with a minimum amount of tools, anyone who knows how to use a screwdriver and wrenches can do this. And if you do everything yourself, you can save time and money on a trip to the service center.

Our VAZ-2112 is unlikely to have any value if it is impossible to move it. Moreover, for such a banal reason as a malfunction of the ignition switch. An essentially trivial breakdown can lead to loss of time, and sometimes even to the loss of the car itself if the ignition switch is faulty.

Replacing lock cylinders

Once the panel is removed, you can begin replacing the door lock cylinder.

It is necessary to disconnect the rod going from the cylinder to the lock by prying it with a screwdriver from the drive side of the cylinder.

Next, use pliers or a screwdriver to pry the cylinder lock and remove it from the door, then insert a new cylinder and assemble everything in the reverse order.

All that remains is to pull out the larva.

Replacing the trunk lock cylinder is somewhat simpler.

To do this, remove the trunk lid trim, after which full access to the entire lock mechanism opens.

We unscrew the bolt securing the button with the cylinder to the trunk lid, and remove the mechanism assembly, disconnecting it from the rod going to the lock itself, and replace it with a new one.

We install and assemble the trunk lid in the reverse order.

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:

1. 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.
2. Now you need to lower the steering column all the way and remove the plastic casing, after unscrewing the screws.
3. Using a chisel, unscrew the bolts with cut heads and pull them out with pliers. Hammer blows should be directed clockwise.
4. Now you can remove the bracket and the lock itself from the steering column by disconnecting the electrical connector.
5. If the backlight lamp needs to be replaced, the contact is disconnected and its socket is removed with pliers. Installing a new device.
6. To replace the contact group of the ignition switch of a VAZ 2110, 2111 or 2112, the clamps are released.
7. If the microswitch stops working, unscrew the screws, remove the rod, and pull out the latch. We install a working device.
8. We replace the contact group of the ignition switch of VAZ 2110, 2111 or 2112.
9. 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
10. 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.
11. Now you can break off the heads from the bolts.
12. Once again we test the functionality of the mechanism. If everything is in order, you can connect the contacts.
13. 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.

Replacing the ignition switch on a VAZ-2112

Replacing the entire assembly will take at most an hour and a half , and the price of a new ignition switch on a VAZ-2112 is within 1,000 rubles .

The ignition switch on the VAZ-2112 is a very capricious thing! We have already changed it on our editorial machine

Sometimes you can save money and change only the contact group. Then replacing it yourself and purchasing a separate contact group will cost three hundred rubles at most.

Removal

We can talk about the reasons for the lock breakdown and possible malfunctions for a long time, but if the task is to remove the lock, then this can be done in half an hour if you follow a fairly simple algorithm of actions, but first you should listen to simple advice :

Any work with electricity requires disconnecting the battery. The first safety rule is to remove the negative terminal from the battery or turn off the ground switch, if there is one.

Only after this can you start working. And yet, it wouldn’t hurt to organize decent lighting. Working in the area of ​​the steering column is always associated with cramped conditions and lack of light. By spending a few minutes organizing good lighting, we will save a lot of time and nerves during work.

In addition to the standard set of keys and screwdrivers, a hammer and chisel will be useful. It’s better to find two hammers to compensate for the impact force, but for now we remove the lock in this order:

1. To access the ignition switch, it will be necessary to remove the decorative plastic casing, and it is more convenient to do this with the steering column lowered all the way. The adjustment mechanism lever is located directly under the steering wheel.
2. Now you can remove the casing, and for this you need a Phillips screwdriver. We unscrew all the screws and carefully remove the plastic casing.

Checking the lock's functionality and steering wheel lock test

All that remains is to check the functionality of the new lock and the steering wheel lock. You should start by checking the lock, to do this you need to remove the key from the ignition and turn the steering wheel slightly.

If there is no lock, it is necessary to adjust the position of the lock. Be sure to make sure that it fits into the groove on the steering shaft.

If the steering lock works as expected, tighten the breakaway bolts until they stop.

After this, connect the power and try to start the engine. If successful and the ignition system is operating correctly, you can tear off the bolt heads and begin installing the steering column casing and steering column switches back into place.

An important nuance is the use of breakaway bolts. Many people use regular ones instead, because this simplifies the subsequent replacement of the lock when it breaks again. But do not forget that breakaway bolts are used primarily to make life difficult for attackers when trying to steal a car, so you should not neglect them.

If you carefully follow the instructions and do everything slowly, then replacing the ignition switch is not a difficult job. The most unpleasant stage will most likely be the first removal of the lock and unscrewing the breakaway bolts. Also, try to buy new spare parts only from trusted sources, so that later it does not turn out that the repair was carried out correctly, but despite this, nothing works and the car does not start.

Where is the ignition switch located on the fourteenth

In VAZ-2114 cars, the ignition switch, unlike classics, is not located on the instrument panel, but on the right, on the steering column. The top is covered with a plastic lid, so only the upper part of the larva is visible to our eyes.

switch consists of five main parts:

• steel case;
• locking mechanism;
• blocking device;
• contact Group;
• key.

The device is housed in a steel case, which is designed to be burglar-resistant. As for the locking mechanism, it is practically no different from a regular door lock.

The locking device allows you to lock the steering shaft in the absence of a key. In this simple way, it protects your car from theft. Contact Group. this is the element that is responsible for starting the engine and its systems. The VAZ-2114 ignition key is used to unlock the locking device and activate the contact group. Without it, it is impossible to start the engine without disassembling the device.
