Then open the driver's door from inside. On some models of cars, you will not succeed. Therefore, Reach, and open the hood. If alarm system worked, it means that everything is ok. If not, it should definitely put another one. Do not trust what is written in the instructions to the machine. Sometimes there is a record of the presence of signaling, but its not. And turn it off at the station can have authorized dealer.
This is done very easily. One way to close the sensor opening hood and all. Your alarm is remote central locking. Manage the locks would stick, and keep cars there. Then you of the alarm should be included, of course for the money, or put another. So since we are trying to get some more money. So we figured out with alarm, but this is the first and cheapest step to protect your car.
Further, if you have a car with automatic transmission, I recommend to put a lock on the box. They are pin without pin. By efficiency, they are identical, the only difference is convenience. In the pin when you need to unlock pull the pin and where to put it. In no whip you in the center console out the core. All management is key (just like in the apartment), he turned to one side, closed, opened at another. And even within passed the motion pin, which locks the box. But it is more expensive, though not by much. Often manufacturers dragon, BEAR-LOCK, MUL-T-LOCK. As for the quality they are virtually identical. Why did I say about the automatic gearbox, because when the machine standing in the parking lot, with a closed lock, it can not roll. If you put a block on a mechanical box, then under its own power machine: whether it be Chevrolet or Opel, or any other model, will not go away, but roll, replacing the clutch can be. Therefore, the unit performs the same role as the alarm system or immobilizer, and put it on the mechanics of a waste of money. Of course in different brands of car locks effectiveness varies. For example, on mercedes or bmw efficiency is very high. And on toyota volkswagen, or below, as there is access to the gear box under the hood. But all the same under the hood you can put special breakaway screws, which are not allow to bypass the lock box.
