ABSTRACT:
A lock cylinder with a lock cylinder housing is provided. A knob shaft, rotatable by way of a knob, is mounted to rotate on one side or both sides of the lock cylinder. An authorization signal causes at least one electromechanically operating coupling device to connect a lock element to rotate in unison with the knob shaft and in order to operate a lock. The authorization signal is generated by evaluation electronics based on an input or input signal. It is proposed that at least one reading unit with an input unit to record the input and/or a receiving unit to receive the input signal is present, that the reading unit with the input unit and/or receiving unit is arranged in at least one knob and are spatially separated from the evaluation electronics, that the knob is connected electrically and mechanically releasable to the knob shaft, and that the reading unit generates, from the input or input signal, an access signal that can be evaluated by the evaluation electronics.
