A lock assembly comprises a plunger reciprocally mounted in a support means, a spring for biasing the plunger in an unlock direction and for holding the plunger in an unlock position, the plunger being movable against the spring bias into a lock position, and link members for holding the plunger in the lock position. The assembly further includes a solenoid having a shaft adapted to operate the link members to release the plunger from the lock position to permit the plunger to be moved by the spring to the unlock position, and an entry console in electrical communication with the solenoid and operable to send an unlock signal to the solenoid upon entry of a selected entry signal.
