ABSTRACT:
A lock actuated by an insertion object. The actuated lock has a housing. The housing has an insertion slot for the insertion object. The lock has a passageway adjuster to exclude an undesirable insertion object. The lock has a first retainer which is vertically adjustable to a plurality of vertical positions. Each vertical position defines an insertion object passage. The insertion object passage has a length which is measured by the distance between the first retainer and the passageway adjuster. The insertion object travels in a pathway through the insertion slot, then through the passageway adjuster, and then through the insertion object passageway. The lock has a design which permits changing its handedness.
