ABSTRACT:
A lock adapted to be used in conjunction with a slidably insertable card comprises a front housing segment and a rear housing segment, a bolt movable along a slide path from a normally open position to a fully locked position, a card housing, a lockout member with a first blocking position and movable to a second release position, a blocking member affixed to the lockout member, and normally disposed in the slide path of the bolt but movable out of the slide path of the bolt. The lockout member also has a peg that engages opening in the card and in the front housing segment constructed and arranged to receive the peg and allow free movement of the bolt into the fully locked position. An improper card or a proper card inserted improperly will not allow the peg to move into the opening, and the blocking member will remain in the slide path of the bolt, preventing the lock from being locked.
