Can be.

Other convenient devices can be equipped with a remote control key (21) to allow the car door to be opened or closed at long distances and a radio frequency identification (24) to identify the vehicle. have.

If an outside intruder enters without the owner's permission, the intrusion detection sensor operates and notifies the outside through the alarm device and uses the engine immobilizer sensor to prevent the intruder from driving the vehicle.

The engine immobilizer is basically provided with three independent immobilizers, one of which preferably has an engine fuel supply shutoff function. In addition, the immobilizer is automatically operated within 5 to 30 seconds after turning off the start, it is to be automatically controlled so that arbitrary operation is impossible by the user.

The switch-off device of the immobilizer generally adds a device that prevents the engine from starting electrically, in case an intruder acts to shut off the immobilizer switch. By controlling its own electronic central control, it is designed to prevent source theft and to design a single color to prevent vehicle theft specialists from identifying wiring, especially in the wiring harness with electrical connections.

In addition, a remote control device of the stolen vehicle leaving system may be provided. In the case of a wired remote control device, an electronic key having a special ID may be mechanically combined to check access authority.

In the case of the wireless remote control apparatus proposed by the present invention, a code hopping scheme, which is an advanced encryption transmission decryption technique, is used so that a code cipher cannot be decrypted by a code grabber scanner.
