How often did you have to stand for a long time and press the buttons of the car alarm stick because of its inoperability, and you did not know how to turn off the alarm? Or you came out of some place and you realize that the car keys are in place, but the key chain has disappeared somewhere. Of course, such situations do not happen so often, but still happen, and how to be in this case, let's try to figure it out.
In order to understand how to turn off the alarm, there are several options. First, you can break the glass so that the signal does not work, or lower it slightly, after which the wire that leads to the transmitter is gently cut off. Another way to turn off the alarm is to use an electric shock. To do this, you need to put several bits on the glass so that they act on the transmitter, which is fixed on it. It is also possible to create noise interference, while using special devices. First, the frequency of the transmitter's operation is recognized, and then it is subjected to noise interference.
How to turn off the alarm without a keychain, knows not everyone, so you should disassemble everything in detail. At the first stage, you should turn off the siren so that it does not irritate others. In case you have the keys to the car, you can open the hood, find the place where the siren is located, and cut the wires. The bell is poured with mounting foam, but this is in case the siren works autonomously. If there is no foam at hand, then you can use a hammer and hit hard, of course, it's a pity, but what can I do? But how to turn off the alarm if there are no keys? To do this, you need to look under the car, that is, lie down on the ground and find a tighter siren and tear off the wire that is suitable for it.
When the first stage is finished, the sound signals stop and only the flashing lights remain. Now let's start searching for the main signaling unit. It can be found by the clear clicks that the relay emits. In most cases, this procedure should be carried out on those cars where the injector or immobilizer is installed. One of the best ways to turn off the alarm in the car is that you know exactly which alarm is set, or you have a printout where the colors and wire numbers are clearly spelled out.
There are various ways to work locks: it can be performed on a closed relay, on an open, LAN-based bus, or even it is built-in. In the first case, you can simply break off the wires, thereby de-energizing the relay. In the second one, it is necessary to ground one of the wires, for this purpose a jumper is placed. The next type of interlock can be removed by interconnecting the two wires that enter the block.
On cars with carburettors, you can even not look for the location of locks, in order to start the car, you need to connect the positive terminals of the battery and the ignition coil. On diesel engines with solenoid valves, it is necessary to connect the positive terminal of the battery and the valve terminal to the injection pump. Thus it turns out that in order to start the engine, you just need to apply voltage to the wire of the retractor relay.
Your alarm is off, have a good trip!
