ABSTRACT:
An antitheft apparatus for an automotive vehicle includes: door lock mechanism assemblies (110, 210, 310 and 410) for locking vehicle doors, respectively; constraining (stopper) members for constraining the door lock mechanism assemblies once actuated to a lock status so as not to be unlocked, respectively; a set switch (125) for outputting a constraint command for constraining the door lock mechanism assemblies once actuated to the lock status so as not to be unlocked; and a controller (1) responsive to the constraint command outputted by the set switch, for first locking the doors by the door lock mechanism assemblies and then constraining the door lock mechanism assemblies to the lock status by use of constraining members, respectively. When the command for constraining the door lock status is outputted, since the doors are first locked by the lock mechanism assemblies and thereafter the lock mechanism assemblies are constrained to the lock status, even if the door is unlocked after the doors have been locked, it is possible to securely constrain all the doors to the lock status.
