ABSTRACT:
An apparatus and method are presented for opening an access door having a latch opposite a hinge. The latch locks the access door in a closed position, and may include a pair of parallel locking pins and a connecting member joining the locking pins. The locking pins extend outwardly from the access door and into a pair of holes in an adjacent portion of a frame surrounding the access door. The latch may also include one or more resilient members (e.g., springs) urging the locking pins into the pair of holes. The connecting member and an adjacent fixed portion of the access door are separated by a distance d, and the locking pins extend a distance l into the pair of holes. The present method includes providing a prying member having a first lateral dimension s where s.gtoreq.(d+l) and a second lateral dimension w where w.ltoreq.d. Dimension w of the prying member is inserted between the connecting member and the adjacent fixed portion of the access door. The prying member is then rotated about an axis substantially perpendicular to the planar face of the access door until dimension s exists between the connecting member and the adjacent fixed portion of the access door. The rotating causes the locking pins to exit the pair of holes, thus unlocking the latch. Once the latch is unlocked, the access door may be opened by rotating the access door about the hinge.
