ABSTRACT:
An antitheft apparatus for an automotive vehicle comprises: a transponder (1) buried in an ignition key to store an ID number thereof; a transmit and receive unit (2) provided in an ignition key cylinder to receive the ID number of the ignition key inserted into the ignition key cylinder; and an immobilizer unit (3) for, in antitheft mode, collating the received ID number with a number of stored ID numbers, and outputting an engine start enable signal when the received ID number matches one of the stored ID numbers and an engine start disable signal when does not match. In particular, the immobilizer unit (3) releases an ID number register mode into the antitheft mode automatically, when the received ID number is read twice successively by the transmit/receive unit or when is the same as one of the already stored ID numbers. On the other hand, after any given number of ID numbers have been registered, the ID number register mode can be also released automatically. Therefore, the ID number register mode can be released automatically after any given number of ID numbers has been registered.
