Removing and installing the ignition lock on a VAZ 2104 car does not require large-scale disassembly of the instrument panel, special skills of the owner, as well as any professional tools.
Malfunction of the ignition switch
Electrical equipment is a rather fragile system of a car, consisting of many component parts and causing known troubles to many motorists. Even a single disconnected contact can create a lot of problems. And the situation when the vehicle does not start at all is familiar to almost every driver and always makes you nervous.
One of the reasons in the domestic car VAZ 2104 in the above situation may be a faulty ignition switch, if, for example, the contacts are burnt out. In addition, it must be replaced in such trivial cases when the key is lost or broken, and, incidentally, the ignition switch mechanism itself is not particularly reliable. The damaged mechanism is not able to perform its direct function of the interrupter - to close the contacts and, accordingly, transmit a "command" to start the engine.
Ignition Lock Removal Tools
The ignition switch on the "four" is located on the left side of the steering wheel under the dashboard of the car. It is fixed to the bracket that holds the steering gear. Usually, in order to replace the ignition switch, a simple tool is required. Two screwdrivers are fine for this purpose. One is a cross, the other is as small as possible. Instead of the latter, it is quite possible to use an awl. And, of course, do not forget to get a new serviceable lock from the car dealer.
Checking the ignition switch
If you have a multimeter in your arsenal, the contact group of the lock can be checked for operability. For this, the terminals of the device are alternately connected to the contacts of the lock corresponding to each specific position of the key. Normally, the resistance should tend to zero.
The procedure for replacing the ignition switch
When replacing the ignition switch on a car, a strict sequence of steps must be followed. It is imperative to remove the "minus" terminal from the battery, then set the ignition key to the "0" position (in fact, it will be located horizontally).
The next step is to unscrew the fastening screws of the plastic cover of the steering column of the car. Part of the cover is separated and you can start removing the ignition lock. On the "classic" it is held with two screws. When these screws are unscrewed, use a thin screwdriver or an awl through the hole in the bracket to gently press the lock catch and remove it from the mounting mount.
The contact terminals are removed from the old lock and connected to the new one. The installation of a working ignition switch and the assembly of the plastic housing of the steering gear are carried out in the reverse order.
