Keys and ignition switch for Lada Granda.

Malfunctions of the ignition switch LADA “Granta”

Ignition switch failures can be divided into two types: electrical and mechanical. Electrical faults include malfunctions of the contact group of the lock, as a result of which individual energy consumers (most often the starter) or the entire Granta electrical system as a whole stop working. This also includes a breakdown of the car's immobilizer. Mechanical malfunctions occur due to breakdown of parts of the ignition switch or contact group, as well as physical wear of the contacts. This also includes cases when, due to poor contact, heating and melting of the plastic parts of the contact group occurs. Signs of a malfunction in the ignition switch of the LADA Granta:

• the key does not turn;
• when turning the key the ignition does not turn on;
• The starter or other electrical appliances do not work.

The last two signs do not necessarily indicate problems specifically in the ignition switch, but they certainly appear when the contact group is faulty.

To eliminate the malfunction, it is necessary to replace the LADA Granta ignition switch or part of it, for example, a contact group.

What is needed to replace the Granta ignition switch

To replace the ignition switch you will need:

• key to 10;
• a thin chisel and a hammer (or a drill with a drill bit to drill out bolts with self-cutting heads);
• screwdriver;
• new ignition switch LADA “Granta” or contact group.

Video review of replacing the ignition switch on a Grant

To understand this procedure more clearly, I suggest that you familiarize yourself with the video review of this repair presented below.

Since the design of the fastenings and the lock itself is no different from the tenth family, you should not pay attention to the fact that the review is shown using the example of the tenth.

Tools:

• Ratchet wrench
• 10 mm head
• Medium Phillips screwdriver
• Small flat screwdriver
• Driver for socket attachment
• 8mm wrench attachment
• 24mm wrench attachment
• Chisel and hammer or electric drill
• Long nose pliers

How to replace the ignition switch of a LADA Granta

The work can be done both indoors and outdoors. To avoid a short circuit, before removing the ignition switch, you must disconnect the ground terminal from the Granta battery. The ignition switch of the LADA “Grant” is removed as follows:

• Unscrew the five lower screws securing the steering column casing;

  

• Unscrew the left and right side bolts securing the casing;
• dismantle the lower part of the “Grants” steering column casing;
• remove the upper part of the casing;
• squeeze the latch of the wire connector connected to the ignition switch;
• disconnect the connector from the contacts of the Grant ignition switch;
• release the lock of the immobilizer antenna unit wire connector;
• disconnect the connector of the antenna unit of the LADA “Grant” immobilizer;
• using a thin chisel and a hammer, unscrew and remove the bolts with self-cutting heads that hold the ignition switch to the steering column or drill out the bolts with a drill;

  

• remove the LADA Granta ignition switch from the steering column.

Tip: it is not necessary to change the lock assembly. It is cheaper to find the cause of the breakdown and limit yourself to replacing one part, for example, a contact group.

Replacing the ignition switch yourself

Unfortunately, the Lada Kalina cannot please you with its reliability and durability; many systems, including the ignition switch, fail within a couple of years, so in order to save on repairs at expensive car repair shops, it is better to find out how to do it yourself. So, having come to the conclusion that the lock needs to be changed, we buy a new lock, which costs around a thousand rubles. In the kit we will receive three cylinders (on the doors and trunk) and 2 keys. You also need to purchase four shear bolts , since the old ones will no longer be suitable after dismantling.

In addition to the product itself, we will need the following tools:

• chisel;
• two screwdrivers, a flat one for removing the clamps and a cross for the bolts;
• 10mm wrench or 10mm ratchet;
• key to 8.

Let's get started

1. First you will need to disconnect the battery cable from the negative.

2. Armed with a cross-head screwdriver, unscrew the fasteners on the steering column. To make it more convenient for you, we immediately warn you: there are two bolts on the right and left sides (3), two at the bottom in the middle (2), and two at the very bottom (1). There is also a self-tapping screw located directly under the steering wheel (4).

How to disassemble the ignition switch of a LADA Granta

To disassemble the ignition switch, follow these steps:

• bend the wire harness clamp on the Grant ignition switch connector housing;
• remove the terminals with wires from the housing;
• Squeeze the latches securing the plastic cover and remove it from the lock;
• press out a pair of plastic clips of the contact group;
• pull the contact group out of the lock body.

After disassembling the lock, it is necessary to inspect the condition of the contact group and terminals on the wires and clean them with fine sandpaper or replace them with new ones.

Assembling the ignition switch and installing it on the LADA Granta is performed in the reverse order of disassembling and removing it from the car.

Installing the ignition switch

A new lock on Granta can be purchased at a price of 1,800 rubles. This is the cost of the kit with all the door cylinders and trunk lid. Installation is carried out in reverse order. We first install it on the shaft and try on the casing so that the lock sits exactly in the hole. After which you can finally tighten the fastening bolts.

It is necessary to tighten until the head of the bolt comes off when a certain torque is reached.

After which you can install the casing in place, having previously connected all the power wires.

Pinout of the ignition switch for LADA “Grant”

The number of ignition switch connector terminals on the Grant has been reduced to three:

• contact “30” (“plus”, connected to the ignition switch);
• contact “15” (circuits powered when the ignition is turned on);
• contact “50” (power supply for the starter solenoid relay).

The ignition switch has three positions: “ignition off”, “ignition on” and “starter”. Accordingly, the power circuit is either open or supplied to the ignition or to the ignition and the solenoid relay at the same time.

Ignition switch Lada Granta - removal, disassembly and maintenance

The main purpose of the Lada Granta ignition switch is to supply and disconnect power to the main electrical consumers of the car in various operating modes.
In other words, the ignition switch can be considered the main power distributor, the condition of which largely determines the normal operation of the car. Among other things, the Lada Granta ignition switch is combined with a mechanical locking device, a key position sensor and an immobilizer antenna control unit.

The operation of the locking device and the contact group of the switch is synchronized to provide control from the ignition key.

It should be admitted that the Lada Granta ignition switch is quite reliable, however, due to the high workload of this element, it is possible that sooner or later it will need to be dismantled for the purpose of replacement or, at least, prevention.

Sequence of operations when removing a VAZ-2190 (Lada Granta)

First of all, as with other work related to tampering with the car’s electrical system, the corresponding power wire should be disconnected from the negative terminal of the battery, after which, to facilitate access to the switch, the protective cover is removed from the steering column;

To disconnect the block connected to the contact group of the lock, release the latch. In the same way, disconnect the block from the immobilizer antenna control unit;

Due to the fact that the lock body is secured to the steering column using bolts with self-cutting heads, a hammer and chisel are indispensable in this case. Alternatively, you can use a drill to remove the bolts;

Next, it is necessary to check the condition of the wires in the most critical place (connection block) and carry out inspection and maintenance of the VAZ 2190 ignition switch as such.

Inspection of the connecting block and prevention of lock elements

Press the latch on the switch wiring harness block and carefully remove the contacts with the wires. Inspect the contacts for oxidation and damage at the soldering (crimping) points. Reassemble the block in reverse order;

Squeeze the side latches and, without applying additional force, remove the plastic cover from the switch body;

Squeeze out the plastic clip and remove the contact group;

Inspect the plate located on the light guide and if oxidation and scorch are detected, clean the contacts with fine-grain sandpaper;

If the damage is too severe, replace the contact plate. To remove the plate, it must be rotated so that the mounting protrusions are aligned with the corresponding slots;

After removing the plate, check the condition of the return spring and if it is cracked or completely broken, replace it;

In the same way, the contacts of the main contact group are cleaned of contaminants, and if it is impossible to perform this operation efficiently, the contact group is changed completely (after having unsoldered three wires);

When reinstalling the spring and slip ring, make sure that the protrusions on the inner surface of the light guide are opposite the widest outer protrusion of the plate.

Upon completion of assembly, it is recommended to check the serviceability of the ignition switch when moving the key to all operating positions, taking into account that the main voltage from the battery and generator is supplied to contact “30”:

Position “0” - all systems are turned off;

Position “I” (ignition) - power is supplied to control devices on the engine management system, generator excitation winding, headlights, turn signal lamps, window cleaners and washers, as well as electric window lifts;

Position “II” (starter) – voltage is applied to the same systems as in case “I”, in addition, the starter is activated.

If the lock is installed correctly, then with the key removed (after setting it to position “0”), the locking rod of the anti-theft device should extend and retract when the key is moved to position “I”. Also, the locking device should not allow the starter to be turned on again (from position “I” to position “II”) without returning the key to its original position “0” (off).

General engine starting techniques

The methods for starting an injection engine on a Lada Granta VAZ 2190 are the same at any temperature of the outside air and liquid in the engine cooling system.
To start the engine on a Lada Granta VAZ 2190, you just need to turn on the starter without touching the gas pedal. The engine control system will independently set the fuel supply and ignition timing parameters necessary to start the engine. 1. Open the hood by pulling the hood lock drive handle towards you.
2. Using an oil dipstick, measure the oil level in the engine. NOTE On a VAZ 21126 engine, the oil level should be between the upper and lower scale marks (within the notch on the dipstick). . and on VAZ 11183, VAZ 21116 and VAZ 11186 engines - between the “MAX” and “MIN” marks.
