Title: Vehicle security system with multi-vehicle compatible interface module for door locks and associated methods

Abstract: A vehicle security system is for a vehicle having a door lock circuit including a door lock switch, and a door lock controller responsive to the door lock switch. The security system includes a security controller for operating the door lock controller, and a multi-vehicle compatible interface module for interfacing to the door lock circuit of a given vehicle from among a plurality of different vehicles. In particular, the vehicle may include a single-wire door lock circuit having at least one of a lock resistance and an unlock resistance associated with a door switch. The multi-vehicle compatible interface module may include a circuit board carrying at least one variable resistor that is settable to match the lock/unlock resistance and thereby permit the security controller to operate the door lock controller.
