A lockable enclosure includes a housing and an access door. The access door includes a hinge portion connected with a first side wall of the housing and is pivotable about the hinge portion between closed and open positions. When the access door is in the closed position, the hinge portion of the access door is slideable for sliding movement of the access door between a latching position in which a first latch portion of the access door engages a corresponding second latch portion of the housing to secure the access door in the closed position, and a release position in which the first interlock portion disengages from the second interlock portion to permit pivoting movement of the access door from the closed position to the open position. The access door further comprises at least one locking feature configured to secure the closed access door in the latching position.
