Abstract
A central control system for the door locks of a motor vehicle has a central unit connected to the door locks via a control line and the door locks each have a first electrically-operable actuator and a second electrically-operable actuator together enabling the 'operate', 'locked and unlocked', 'antitheft mode on and off' and 'child-safety mode on and off' operations. The door locks can be mechanically identical and can have a keeper pawl controlled both by the first actuator and an interior lever which is effective only when the second operator has displaced a lever from its ineffective position into an effective position.
