Access door with inside latch release

An apparatus and method providing a quick-release latch mechanism for a walled enclosure access door. The latch mechanism includes a striker with one end slidably inserted into the enclosure and the other end located outside the enclosure. A keeper is located within the enclosure and adapted to releasably engage and be captively held by the striker when the access door is in the closed position. If necessary, the access door can be readily unlatched from within the enclosure by manually rotating the keeper away from the enclosure wall to disengage and cause removal of the striker as the access door is being manually pushed open from within the enclosure.
