Abstract

A lock system for access authorization in a motor vehicle, having a first device which has at least two states and is embodied as a control device, and having an associated second device which is embodied in the manner of an electronic key, an ID signal transmitter, a chip card or the like. The two devices have transmitters and/or receivers for electromagnetic signals. At least one of the signals transmitted between the second device and the first device is an encoded operating signal for authenticating the second device, with the result that after a positive evaluation of the transmitted operating signal when the second device is authorized it is possible to bring about a change in the state of the first device.
