A vehicle antitheft system comprises an ID code compare unit 13S for comparing a key ID code obtained from an ignition key with a reference ID code stored in advance in the vehicle and generating an enable code when these ID codes come in a preset relationship (for example, identical), an engine ECU 16 for receiving the enable code and enabling control of the engine when the enable code is correct, and delay means 13T started in response to generation of the enable code and generating a signal which enables starting of the starter motor with lapse of a preset time (for example, at least a time necessary for the engine ECU 16 to store or identify the enable code) to avoid adverse effect of noise from starting the motor. <IMAGE> |
