Abstract: A locking system is provided whereby at least two locking devices can be actuated with one and the same key. The key has at least two control tracks, via which, in at least two scanning planes lying one behind the other respectively transverse to the insertion direction, the scanning of scanning points provided on the key is possible. Via the scanning points provided in at least one scanning plane, both types of platelet tumblers can be scanned via the mating scanning points thereof and separated, so that the arrangement of one type of the two platelet tumblers in at least one scanning plane can be chosen freely in order to form a multiplicity of locking devices having cylinders cores having an associated cylinder housing and matched to the free choice of the platelet tumblers, which can be actuated with one and the same key.

Abstract: A lock device having a lock cylinder and a flat key having a control gate. The lock cylinder has a cylinder housing and a cylinder core rotationally supported in the cylinder housing and a plurality of plate-shaped tumblers that are supported in the cylinder core so as to be radially slidable with respect to the rotational axis of the cylinder core and which each have a key opening and are at least partially pushed by the spring load into a locking channel of the cylinder housing in order to lock the lock cylinder when the flat key is removed and which are slid into an unlocking position by the control cam guided in the control gate when the key is inserted. At least one stop is associated with each of the tumblers in order to limit the sliding path to conceal the unlocking position.
