An elevator system () includes a hoistway () having a plurality of landing floors () each landing floor () having a landing floor door (). An elevator car () is positioned in and drivable along the hoistway (). A controller () restricts operation of the landing floor doors () based on a position of the elevator car () along the hoistway (). A method of operating an elevator system () includes driving an elevator car () along a hoistway () of the elevator system () and determining a position of the elevator car () in the hoistway (). Operation of a plurality of hoistway landing floor doors () is controlled based on the position of the elevator car () in the hoistway ().

Elevator car location zones in hoistway

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.
