Abstract
A landing door locking mechanism of an elevator system includes a body housing key-engagement elements and having a first end and a second end, the key-engagement elements located at the first end and a keyway structure, wherein in a first position the first end of the body is exposed such that a key may be inserted into a keyway of the keyway structure and interact with the key-engagement elements. A biasing mechanism is configured to bias a moveable portion of the body toward a second position, wherein in the second position a key cannot interact with the key-engagement elements and a solenoid is configured to apply a force on the moveable portion of the body when the solenoid is energized such that the moveable portion of the body is moved from the second position to the first position.
