A locking mechanism for use on watertight doors includes a mounting plate having a threaded shaft on one side and an eye element on the other side. A chain associated with the watertight door is securely attached to the eye element and is adapted to be padlocked to a lock on the watertight door to lock the door against unauthorized entry into the compartment associated with the door. A threaded nut is threadably attached to the threaded shaft. The threaded shaft extends through a bore defined through the bulkhead associated with the door into the interior of the compartment associated with the door. In the event of an emergency, the threaded nut is removed from the threaded shaft, and the locking mechanism can be removed from the bulkhead associated with the door thereby freeing the door from the bulkhead and permitting the door to be opened from inside the compartment even if the chain remains locked to the door.
