Abstract: An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.
