Lock comprising a lock housing (10) in which are accommodated: a first follower (13), at least one coupling member (16, 17), which by means of the first follower is movable between a locked and an unlocked position for actuation of a lock bolt, a second follower (40), and a blocking element (50), which by means of the second follower is movable between a blocking position, in which the coupling member is blocked in its locked position, and a release position, in which the coupling member is movable at least from the locked into the unlocked position. A latching member (60) is arranged to allow latching of the blocking element in its blocking position. The second follower, the blocking element and the latching element are accommodated in an encapsulated modular unit (30) which is fitted as an integrated unit in the lock housing.
