A locking mechanism for the doors of an elevator car, which usually permits the doors to be opened by an amount insufficient for a passenger to exit from the car and then locks the doors with respect to further opening movement, is rendered inoperative when the car is close to a landing. The on mechanism includes latching means comprising stop means 112 on the car and locking means 111 on the door engageable with the stop means, and operating means 114-127 on the door for preventing the locking means from engaging the stop means, adjacent a landing. An operating strip 114 may be associated with a known clutch mechanism 95-100 on the lift door and rollers 102, 103 on the shaft doors, which latter forms a stop for the strip 114 when the car is adjacent the landing.
