A locking system for a lift door, in particular a car door (5) of a lift car (1) and/or a shaft door, comprises a locking device which in an unlocked state enables opening of the lift door, and in a locked state restricts, in particular prevents opening of the lift door; a reference element (18); a counter element (15.1; 152) which interacts with the reference element (18), in particular mechanically, electrically, magnetically, acoustically and/or optically, in a prescribed measure when the lift car (1) is located in a permissible position relative to a shaft door; a sensor (20) for outputting a preferably electrical signal when the reference element and the counter element (15.1; 152) are interacting with one another; and a control device for transferring the locking device from the locked state into the unlocked state as a function of the signal, the reference element (18) preferably being arranged on the shaft door.
