FIELD: construction.
SUBSTANCE: cylinder lock comprises a body with a cylinder installed in it as capable of rotation, comprising a channel for a key, code and stop pins spring-loaded relative to the body and arranged in the cylinder, forming pairs of movable pins, which are arranged in coaxial holes of the body and the cylinder. Each pair of pins is installed as capable of displacement perpendicularly to the longitudinal axis of the cylinder, besides, the channel for the key in the cylinder is made as stepped with a threshold arranged under ends of stop pins. One stop pin or at least two stop pins are arranged as capable of interaction with the threshold of the cylinder channel in its working and non-working positions.
EFFECT: improved secrecy and simplified design.
