ABSTRACT:
A centralized lock system for a motor vehicle, provided with a system-specific identity code word which is stored in memories of the satellite processors associated with the door locks as well as in the code word storage memory of the central processor and the code words are transmitted back and forth along the base or line connecting the electronic controller with the door locks. An identity test is effected at these memories and upon failure of the identity test, the door lock and/or electronic controller or all of the door locks and preferably also the electronic controller are deactivated. This prevents ready replacement of the components since the system will not recognize a foreign component and deactivation will occur upon an attempt to substitute a foreign component for one of the original family of components of the system.
