Abstract

A door lock for motor vehicles having a control element which is driven by an electric motor, is controlled by an electronic control unit and can be moved, upon a control signal emitted by a transmitter, into a position which at least prepares the opening of the door lock. An energy accumulator, which is independent of the wiring of the motor vehicle and which, as required, can be connected to a signal receiver, is assigned to the electronic control system so that the signal receiver will then activate the control element directly.
