<p>A locking device including at least one key and a lock cylinder having at least one cylinder core pivotally mounted in a cylinder housing and having a keyway is provided with a blocking element which in its blocked position prevents rotation of the cylinder core with the key, and in its release position permits rotation of the cylinder core with the key. Further provided are an actuator which blocks the blocking element in the blocked position and releases it in the release position, and an electronic code transmitter in the key and an electronic code evaluator which controls the actuator. The lock cylinder is provided with a cylinder armor having an armor housing covering the cylinder housing and an armor disk pivotally mounted therein with a key insertion slot flush with the keyway of the cylinder core. The blocking element and the actuator are disposed in the armor housing. In its blocked position the blocking element acts on the armor disk so as to prevent rotation, releasing it in the release position.</p> |
