PURPOSE: An audio burglarproof device using an immobilizer is provided to improve convenience for users by automatically setting an audio according to the users by using a cellular phone. CONSTITUTION: In a vehicle having an immobilizer system for controlling starting of an engine by an engine control unit through communications between a coil(22) of a key cylinder(20) and a transponder(12) disposed at a key(10), an burglarproof device is composed of a burglarproof controller(110) for memorizing information about a key identifier input from the immobilizer system, transmitting and encrypting vehicle identification number-added identifier information generated by adding a vehicle identification number of an own vehicle to the key identifier information, and outputting first encryption information; a comparator(120) for encoding the first encryption information and vehicle identification-added identifier information in the transponder and comparing the first encryption information with second encryption information; and a switch(130) for stopping the auto by cutting off power supplied to an audio controller(140) if the first and second encryption information is different from each other.
