Abstract: A lock for a closure element of a real estate property, includes a pivoting catch on which a spring acts in a preferred direction, a locking member, and a manual or mechanical drive device. The locking member is designed as a rotary locking member that is driven by the drive device in a circulating manner about a locking member axis in only one rotational direction and comprises multiple locking elements which are offset to one another over the angle at the circumference of the locking member and which interact with the pivoting catch as respective tumblers depending on the rotational angle. Only one of the locking elements constantly acts directly on the pivoting catch for a locking and unlocking process, and the adjacent locking element opposite the rotational direction of the rotary locking member acts on the pivoting catch by rotating the rotary locking member for a subsequent locking and unlocking process.
