Abstract

A device for locking and unlocking a door lock provided with a door handle on an object, in particular a motor vehicle, has a transmitter unit arranged on the object and a transponder unit assigned to a user. Different methods of operating the device are made possible by designing the door lock as an electromechanical lock which can be locked and unlocked optionally by a manually operable key and/or a button arranged on the inside or electronically by the transmitter and transponder units, and operation is ensured even in the event of a failure of the electric power supply.
