When the “central castle” was invented, many were happy. However, he does not save scattered people, but rather the opposite. Turning the key in the driver’s door lock, keep in mind that at the same time the locks of the other three will open, and on some cars also the locks of the trunk lid, fuel filler flap, “glove box”, etc. Forgetting this, leave the car defenseless. And still the central lock - a convenient thing: clicked the driver’s door lock - everyone else closed. On a photo 1 - a key tested by edition of the KIA Spectra car - uniform for doors, a trunk lid and the ignition lock.

From a specialist point of view, the operation of the electrical control of the locks can be briefly described as follows. When the key is turned, the control contacts trigger the relay command; it, in turn, supplies power to actuators - devices that directly lock or open door locks. The most common actuators with a stem driven through a gear transmission.

On serial Russian cars, electric actuators took root, located in accordance with Fig. 1 (doors 1, 2, 3, 6). Point 4 on our cars is usually unprotected - access to the neck or cap of the gas tank is free. Point 5 - trunk lock. He was first defended on the VAZ 2110.

On many foreign cars you can find the whole range of services, including additional ones, such as controlling the trunk lock directly from the passenger compartment (shown by a dotted line). The actuator managing this entire economy, of course, must be in the driver's door. Here it is, in photo 3. There are five wires from it, let's pay attention to blue and green. Power to electric motors goes along these two. (In the standard wiring of the VAZ 2110, these are yellow and red wires.) The other three are control: they send a signal from the door lock contacts to the actuator relays. The remaining actuators are two-wire, their task is only to unlock-lock. The relay has eight outputs: two provide their own power ("+" and "-"), two more provide power to the actuators' electric motors (along the blue and green wires), the next pair is the control, as already mentioned, by the relay itself from the driver's door actuator. One pair of relay pins is not enabled.

It is curious that some automakers save on the actuator for the driver's door, such as, for example, a VAZ on the “top ten”. The logic is simple: they still open the door with a key - it’s easier to put a cheap switch, as in photo 5.
