Electronic token lock core

A lock system comprising:

• a lock core comprising a core body, a lock actuator coupled to the core body for rotation about an axis, a blocker movable perpendicular to the axis 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, the electromagnetic actuator having a shaft that is movable parallel with the axis between a first position in which the blocker is locked in the locking position and a second position in which the blocker is movable from the locking position to the releasing position, the electric circuit being configured to signal the electromagnetic actuator to move the shaft from the first position to the second position if the token reader reads a valid access code;
• a token that is couplable mechanically to the lock actuator, the token having an access code that is read by the token reader when the token is coupled mechanically to the lock actuator, the electric circuit signaling the electromagnetic actuator to move the shaft parallel with the axis from the first position to the second position so that the blocker is movable perpendicular to the axis from the locking position to the releasing position if the access code read by the token reader matches the valid access code;
• a lock cylinder, the lock core being couplable to and decouplable from the lock cylinder, the lock core further comprising a tumbler element that is movable between a coupling position in which the lock core is prevented from being decoupled from the lock cylinder and a decoupling position in which the lock core is decouplable from the lock cylinder;
• the token reader reading the access code and the electric circuit signaling the electromagnetic actuator to move from the locking position to the releasing position when the token is coupled mechanically to the lock actuator, the tumbler element remaining in the coupling position when the token is coupled mechanically to the lock actuator;
• and
• a second token that is couplable mechanically to the lock actuator, the second token also having the access code, the token reader reading the access code and the electric circuit signaling the electromagnetic actuator to move from the locking position to the releasing position when the second token is coupled mechanically to the lock actuator, the tumbler element moving from the coupling position to the decoupling position when the second token is coupled mechanically to the lock actuator.
