The invention relates to a lock-key system which comprises a lock cylinder, in the lock cylinder housing of which a cylinder core is rotatably mounted, said cylinder core having a key way for insertion of a flat key or reversible key with a longitudinal profiling on the lateral faces of the key shank. The key shank has a milled section extending away from the key back, a bead-type control element being rotatably arranged on a longitudinal axis of the key shank. Said control element cooperates with a tracer pin which in turn influences the movement of a blocking pin. |
