A lock mechanism is provided for use with a door assembly. The lock mechanism includes a lock bracket configured to connect to a door or hatch; a lock pin can be selectively moved between an engaged position in which the lock pin engages the lock bracket and a disengaged position in which the lock pin does not engage the lock bracket; and a linkage assembly connected to the lock pin and configured to be actuated to reversibly move the lock pin between the engaged position and the disengaged position, and a door or hatch release device can switch the lock pin from the engaged position to the disengaged position if the door or hatch release device is actuated after the linkage assembly has moved the lock pin into the engaged position.
