In order to extend a conventional access control system using elements of an electronic pass-key system, it is proposed for a control circuit (35) located on the lock side and operating on the basis of authorisation data in an electronic key (31) to be connected to a central unit (1) of the access control system via an interface (49). The data transfer format and the data transfer rate of the interface (49) can be programmed and are controlled by control data which, together with the authorisation data, are contained in the data memory (37) of the electronic key (31). <IMAGE> |
