An elevator door safety lock system ensures that an elevator door remains securely closed when it is not aligned with one of a plurality of floor openings. The safety lock system includes a vertical position sensor which includes an RFID reader disposed on the elevator and a plurality of RFID tags each disposed in the shaft at a different floor opening. The reader identifies when it is aligned or non-aligned with any tag indicating when the elevator is aligned and non-aligned with a floor opening. A control unit communicates with the safety lock system and an elevator controller. A door monitor indicates if the elevator door is open or closed and an engagement sensor detects whether the door lock is engaged.
