Abstract
A lock core for use with a token having an access code and a blade is provided. The lock core includes a core body, a lock actuator coupled to the core body for movement, a token communicator configured to read the access code when the blade is inserted into a passageway of the lock actuator, at least one movable tumbler element, a movable blocker, a biasing member situated between the at least one tumbler element and the blocker, and an electromagnetic actuator coupled to the core body and coupled to the token communicator. Insertion of the token in the passageway moves the at least one tumbler element to store energy in the biasing member. If the token communicator reads the access code after insertion of the token in the passageway, the electromagnetic actuator moves to unlock the blocker and the biasing member releases energy to move the blocker.
