Abstract: A two-way locking system and method wherein a pair of entryway members which are moveable relative to each other may be separately accessed by separate locks from each side. A strap passes between the confronting edges of each entryway member, and a first separate lock is associated with the strap on one face of one of the entryway members and a second separate lock is associated with the strap on a face of the other entryway member on the other side of the boundary formed by the entryway member pair. A person on a first side of the boundary cannot gain access to the lock on the other side of the boundary until the person releases the lock on the first side of the boundary.
