Abstract
A lock system comprises a lock core and a token having an access code. The lock core comprises a core body, a lock actuator coupled to the core body for rotation about an axis, a blocker movable between a locking position in which the lock actuator is prevented from rotating about the axis and a releasing position in which the lock actuator is permitted to rotate about the axis, an electric circuit having a token reader, and an electromagnetic actuator having a shaft that is movable parallel with the axis. The token is couplable mechanically to the lock actuator. The electric circuit signals the electromagnetic actuator to move the shaft parallel with the axis so that the blocker is movable from the locking position to the releasing position if the access code read by the token reader matches a valid access code.
