Abstract
When transmitting an instruction for activating an immobilizer function to a subject vehicle, a base station also transmits a given ID code for releasing the immobilizer function. An immobilizer ECU that receives the instruction and the given ID code, prohibits an engine from being started by other than a key having the given ID code. Therefore, a regular user alone, who owns a key having the given ID code, can start the engine.
