Abstract
In a burglarproof system for an automotive vehicle, a door key cylinder arranged at a vehicle door includes a cylindrical body and a rotor accommodated therein. An acting section provided at the rotor extends radially from an axis thereof. A door key switch arranged in the vicinity of the door key cylinder detects the acting section to output a key-operation detection signal, when the rotor is angularly moved by turning operation of a key to bring a door locking mechanism to an unlocked position. A door lock switch detects in which one of the locked and unlocked positions the locking mechanism is. A stealing detector is provided for outputting a stealing detection signal when the stealing detector does not receive the key-operation detection signal from the door key switch, but receives the lock-releasing detection signal from the door lock switch. A burglarproof unit executes operation for a burglarproof in response to the stealing detection signal.
