A door lock with controllable handle operation including a bolt ( 3 ), a follower ( 5 ) for moving the bolt and an operation axis ( 4 ), on both ends of which an actuator can be installed for operating the follower ( 5 ), whereby force transmission from either side of the lock to the follower ( 5 ) is established by means of movable coupling members ( 10 a, 10 b), which are controlled by a solenoid arrangement ( 8, 9 ) or the like, and in which the follower ( 5 ) is provided with two separate torsion units ( 6 a, 6 b) installed on the operation axis ( 4 ) on different sides of the follower ( 5 ) and turnably secured thereto, which units can be connected to force transmission with the follower ( 5 ) by utilising said coupling members ( 10 a, 10 b). The door lock comprises a selecting member ( 7 ) movable from one lock side to the other, which member retains the torsion unit ( 6 a, 6 b) selected in each case to be unturnable with respect to the follower ( 5 ), so that force transmission from the operation axis ( 4 ) to the follower ( 5 ) is connected on that particular side of the lock, and on the other side of the lock, force transmission from the operation axis ( 4 ) to the follower ( 5 ) can be selectively either connected or disconnected by means of said coupling members ( 10 a, 10 b) under the control of the solenoid arrangement ( 8, 9 ).
