FIELD: construction.
SUBSTANCE: invention relates to locking devices. Substance of the invention consists in the following: changing shape, orientation and arrangement of pins 10, 12 in cylinders 3, 4, 6, availability of a cylinder 5 rotating in one direction with sets of code pins 11, which makes it possible to replace the code at each opening of the lock, for unlocking of which a key is proposed, made in the form of telescopically arranged tubes 17 of different diameter, which are installed as capable of screwing one into another and to control the length of helical motion travel by means of scales made on the external side of each tube.
EFFECT: increased secrecy of a cylinder mechanism due to automatic replacement of codes at each opening of a lock.
