1. A door for an entryway, the door comprising:
an exterior-facing surface;
an inner structure;
a latch mechanism connected to the inner structure, configured to be fastened, such that the door maintains closure of the entryway, and capable of being released, such that the door opens the entryway;
a key-cylinder accessible from the exterior-facing surface and configured to selectively lock and unlock the latch mechanism;
a pawl fixed to and configured to be rotated by the key-cylinder about a pivot axis, operatively connected to the latch mechanism, and defining a pass-through aperture spaced apart from the pivot axis;
a shield defining a shield attachment aperture and connected to the inner structure; and
a security fastener configured to fix the shield relative to the key-cylinder at the shield attachment aperture and extend through the pass-through aperture without impeding rotation of the pawl or contacting the pawl as the pawl operates the latch mechanism.
