A method of unlocking an elevator car door or an elevator car includes operating a door operator and moving a movable vane operably coupled to the door operator. If the elevator car is positioned within a landing door zone, the movable vane is moved into contact with an interlock roller. An engagement latch is rotated to disengage from an electrical contact in response to moving the movable vane into contact with the interlock roller.
