• a first spring capable of biasing the blocking member toward the first position and a second spring capable of biasing the blocking member toward the second position, when the blade of the token is received in the passageway the second spring stores internal energy generated by insertion of the blade to bias the blocking member toward the second position regardless of the access code contained in the token.

A lock core for use with a token including identification information and a bitted blade, the lock core comprising:

• a core body having an aperture;
• a lock actuator received in the aperture, the lock actuator being movable relative to the core body and including a passageway formed therein for receipt of the bitted blade of the token;
• a first barrel partially formed in the core body and partially formed in the lock actuator in communication with the passageway;
• a blade-engaging pin received in the first barrel, the blade-engaging pin having a first end extending into the passageway and a spaced apart second end;
• at least one additional pin received in the first barrel and having a semi-spherical surface that engages the second end of the blade-engaging pin, the bitted blade engages the first end of the blade-engaging pin and positions the semi-spherical surface of the at least one additional pin so that movement of the lock actuator with respect to the core body is not inhibited;
• a blocker movable relative to the core body between a first position in which the blocker prevents the lock actuator from moving relative to the core body and a second position in which the lock actuator is movable relative to the core body;
• and
• a spring situated in the first barrel, the spring engaging the blocker and engaging the at least one additional pin;
• further comprising an electromagnetic actuator having a locking position in which the blocker is prevented from moving out of the first position and a releasing position in which the blocker is movable from the first position to the second position.

• a barrel partially formed in the core body and partially formed in the lock actuator in communication with the passageway;
• a blade-engaging pin received in the barrel having a first end extending into the passageway and a spaced apart second end;
• at least one additional pin received in the barrel and having a semi-spherical surface that engages the second end of the blade-engaging pin, the bitted blade engages the first end of the blade-engaging pin and positions the semi-spherical surface of the at least one additional pin so that movement of the lock actuator with respect to the core body is not inhibited;
• a blocker movable relative to the core body between a first position in which the blocker prevents the lock actuator from moving relative to the core body and a second position in which the lock actuator is movable relative to the core body;
• a spring engaging the blocker and engaging the at least one additional pin;
• and
• an electromagnetic actuator having a locking position in which the blocker is prevented from moving out of the first position and a releasing position in which the blocker is movable from the first position to the second position, wherein movement of the blade-engaging pin and the at least one additional pin by the bitted blade compresses the spring and when the electromagnetic actuator moves to the releasing position, the spring expands to move the blocker from the first position to the second position.

An interchangeable lock core that is configured to communicate with a token having an access code, the interchangeable lock core comprising:

• a core body having an aperture having an axis;
• a lock actuator received in the aperture and being movable relative to the core body;
• a token communicator coupled to the core body;
• a blocking member that is movable transverse to the axis between a first position wherein the lock actuator is fixed to the core body and second position wherein the lock actuator is movable relative to the core body;
• an electromagnet;
• a latch coupled to the electromagnet for movement transverse to the blocking member to couple and lock the blocking member in the first position and uncouple from and allowing the blocking member to assume the second position;
• a first spring biasing the blocking member toward the first position;
• and
• a second spring biasing the latch toward coupling with the blocking member.

A lock core for use with a token having an access code and a blade, the lock core comprising
