FIELD: locks, particularly for operating or controlling locks or other fastening devices by electric or magnetic means.
SUBSTANCE: secrecy mechanism comprises case with key groove. spring-loaded blocker, shaft with arm and tang for lock mechanism operation and key with constant magnets are installed inside the case. Spring-loaded blocker has matrix with blind holes adapted for arranging blocking members. Blocking members are made of m-metal and formed as balls or bodies of revolution with parallel or inclined generating lines. Key groove is through and located transversely to shaft axis. Shaft carries dissymmetrical doubled eccentric member kinematically connected to blocker. Matrix has blind longitudinal cavities and extensions for coded grooves formed in blocker. Constant magnets of the keys are coaxial with coded blocker grooves and with matrix extensions. The case has spring-loaded key fixer. Key includes orifice for fixer receiving.
EFFECT: increased resistance to breaking-in.
