FIELD: locks.
SUBSTANCE: group of inventions relates to a flat key for a cylinder lock, a cylinder lock and a locking system with such a key and a cylinder lock. A flat key for a cylinder lock comprises a key head and a key shaft extending parallel to the longitudinal axis of the key, and has a key tip. At least one surface code formed for analysis in the cylinder lock is located on the end surface of the key tip. On the end surface of the key tip there is at least one additional code with one more scanning surface, which shape differs from the scanning surface of the surface code. Additional code extends along part of end surface.
EFFECT: designing a flat key and a corresponding cylinder lock, which are as difficult as possible to copy, but can be easily manufactured.
