Abstract: A door for an entryway includes an exterior-facing surface, an inner structure, and a latch mechanism. The latch mechanism is connected to the inner structure and configured to be fastened or released for controlling access to the entryway. The door also includes a key-cylinder accessible from the exterior-facing surface and configured to selectively lock and unlock the latch mechanism. The door additionally includes a pawl configured to be rotated by the key-cylinder about a pivot axis, connected to the latch mechanism, and defining a pass-through aperture distal from the pivot axis. The door also includes a shield defining a shield attachment aperture and connected to the inner structure. The door further includes a security fastener to fix the shield relative to the key-cylinder at the shield attachment aperture and extending through the pass-through aperture without impeding the pawl's rotation or contacting the pawl as the pawl operates the latch mechanism.
