An example door interlock includes a baseplate and a keeper removably and pivotally attached to the baseplate. The keeper includes a bore and a grooved opening, where the grooved opening is configured to connect to an arm, the arm connecting a door to the door interlock. The door interlock further includes an actuator including a cylinder. The actuator is configured to insert or retract the cylinder into or out of the bore, respectively, based on a positioning of an elevator, thereby causing the keeper to move between a locked configuration and an unlocked configuration, and causing the door to either be openable when the keeper is in the unlocked position or unopenable when the keeper is in the locked position.
