Abstract
An electromechanical cylinder lock-key-combination includes a key having a mechanical locking code and a device for storing an electronic code and sending it into the lock. A lock body encloses a turnable lock cylinder and a locking mechanism which normally prevents turning of the lock cylinder with regard to the lock body and which can be moved by the key into a releasing position allowing turning of the lock cylinder. The lock includes a special locking disc with which the key is not in direct mechanical force transmission connection, an identification and control device for receiving and identifying the electronic code from the key, and an electric operating device with a turnable coupling member attached thereto and having a free position and a coupling position in which it couples the special locking disc with the turning movement of the key for opening the lock, whereby when there is a match with the correct electronic code of the key the identification and control device activates the electric operating device to guide the coupling member to its coupling position. The coupling member is located and is in cooperation with a guiding groove in the special locking disc, the guid…
