Abstract

The door-lock system for a motor vehicle has mechanical motor vehicle door locks in all motor vehicle doors and the trunk lid, a mechanical lock cylinder in the motor vehicle door lock of the driver's door and a remotely operable electronic operating mechanism with a transmitter acting as an electronic key, a receiver and decoder as well as a power supply. The motor vehicle door locks in the doors have at least one locked configuration and an additional theft preventative configuration as well as a central lock mechanism drive with control positions for engagement and/or disengagement of the theft preventative configuration. The central lock mechanism drive is operable by the electronic operating mechanism. The decoder and the receiver of the electronic operating mechanism are independent components which are connected only electrically. The receiver is located otside, e.g. in the driver's door, and only operates from the outside by a transmitter. The decoder is located in the inside of the motor vehicle and is connected electrically with the central lock mechanism drive. Moreover, an emergency operating device is provided for disengagement of the theft preventative mechanism.
