A locking device for a motor vehicle. A transmitting device, which is designed to send out a request signal into a surroundings of the motor vehicle in dependence on a predetermined triggering event, as well as a receiving device, which is designed to receive, within a predetermined time interval from the sending of the request signal in a predetermined frequency region, a response signal of a radio key from the surroundings, and a control device, which is designed, in event of a response signal received within the time interval, to unlock at least one lock of the locking device. An evaluation module is designed so that the transmitting device sends out an interference radio signal after the sending of the request signal within the time interval at least at one radio frequency lying outside the frequency region.
