A lock device (e.g. releasable door strike/keeper) includes a tongue 30 pivotally mounted in a housing, a latch 33 slidably received in the housing for latching the tongue to the housing, a sliding member 35 located above the latch for forcing the latch to engage with the tongue, a follower slidably engaged in the sliding member 35 and having a projection 41 for moving the sliding member away from the tongue, a lever arm 50 is pivotally attached to the housing and engaged with the follower for moving the follower, a rotary member 55 is attached to the housing and includes a stud engaged with the lever arm for rotating the lever arm in response to actuation of a link 60. Actuation of link 60, e.g. by solenoid, releases latch 33 and allows pivoting of the tongue/keeper 30. The follower 40 may include a cam surface selectively retaining a ball 38 in a recess in the housing.
