Claim 3:
4. A system for controlling access to a restricted access area, the system comprising:
a supporting structure defining at least a portion of the restricted access area;
a supported structure; and
a plurality of hinges each configured for toolless assembly and disassembly and each comprising:
a first attachment plate attached to the supported structure;
a second attachment plate attached to the supporting structure;
a pin comprising a notch in an outer surface of the pin and configured for insertion into the first and second attachment plates for pivotably connecting the first and second attachment plates together, wherein the pin is inserted so that the notch is positioned within the second attachment structure when the hinge is in the assembled state; and
a key that comprises a main body and a distal end extending from the main body, which is configured for insertion within the notch of the pin to prevent the first and second attachment plates from being separated in an axial direction of the pin while the distal end of the key is inserted within the notch of the pin;

wherein each of the plurality of hinges is configured such that the supported structure is movable, relative to the supporting structure, between a closed position, in which access to the restricted access area is blocked by the supported structure, and an open position, in which access to the restricted access area is not blocked by the supported structure; and
wherein the key of each of the plurality of hinges is movable, when the supported structure is in the closed position, such that the distal end of the key can be removed from engagement with the notch of the pin to allow the first and second attachment plates to be separated in the axial direction of the pin.
