ABSTRACT OF THE DISCLOSURE In a lock with a housing and a lock rotor having a key channel receiving a flat key two tumbler rows with pin tumblers and two tumbler rows with pin tumblers are arranged in the axial direction of rotor. The tumbler planes of the tumbler rows are inclined by identical, but oppositely directed angles with respect to the median longitudinal plane of key and intersect the surface of key in the vicinity of the two key edges of the narrow side of key. The recesses of key associated with the pin tumblers are arranged in rows on key edges with one recess portion on the narrow side and the remaining recess portion on the flat sides of key. This arrangement makes it possible to reduce the constructional size of cylinder lock. It also makes it more difficult to open the lock without a key and to illegally copy said key.
