Patent ID: 6854305

Claim:
An electromechanical cylinder lock-key-combination comprising: a key that is insertable in the lock and is turnable in the lock, the key having a mechanical locking code and including a means for storing an electronic code and for transmitting the electronic code to the lock, a lock body, a turnable lock cylinder enclosed by the lock body, a locking means enclosed by the lock body and which normally prevents turning of the lock cylinder relative to the lock body and which can be moved by means of the key to a releasing position allowing turning of the lock cylinder relative to the lock body in response to turning of the key in the lock, at least one special locking disc enclosed by the lock body and with which the key is not in direct mechanical force transmission connection when the key is inserted in the lock, the special locking disc being formed with a guiding groove having a guiding surface and the special locking disc having a locking position in which it prevents turning of the lock cylinder relative to the lock body and also having a releasing position, an identification and control means for receiving and identifying the electronic code transmitted from the key, an electric operating means, and a turnable coupling member attached to the electric operating means and having a free position and a coupling position, whereby when there is a match with the electronic code of the key, said identification and control means activates said electric operating means to turn said coupling member to its coupling position, in which the coupling member engages the guiding surface and thereby couples said at least one special locking disc with turning movement of the key for opening the lock.
