摘要

The invention relates to a locking system (1), in particular on a motor vehicle, which consists of an operating key (2), an operating key receptacle (3) and connecting lines (4) to an associated operating unit (5). The operating key (2) has a first operating signal transmitter (15) with first operating signal encoder (16), and the operating key receptacle (3) has a first operating signal receiver (21) with first operating signal decoder (23), as a result of which a first encoded operating signal can be transmitted from the first operating signal transmitter (15) to the first operating signal receiver (21) when the operating key (2) is inserted into the operating key receptacle (3). In addition, in each case a second operating signal receiver (24) and operating signal decoder (26) are arranged in the operating key (2) and in each case a second operating signal transmitter (27) and operating signal encoder (29) are arranged in the operating key receptacle (3), a second encoded operating signal being capable of being transmitted from the second operating signal transmitter (27) to the second operating signal receiver (24). The second operating signal interacts with the first operating signal in a bidirectional communication in the manner of a changing code, activation of the operating unit (5) being made possible when there is successful decryption of the first operating signal in the first operating signal decoder (23).
