A door includes an exterior-facing surface, an inner structure, and a latch mechanism. The door also includes a key-cylinder attached to and accessible from the exterior-facing surface, and adapted to selectively lock and unlock the latch mechanism, and a pawl adapted to be rotated by the key-cylinder to unlock the latch mechanism. Furthermore, the door includes a feature arranged on the inner structure and aligned with the key-cylinder, and a component connected to the key-cylinder, aligned with and extending into the feature without contacting the inner structure. The component is configured to not impede the rotation of the pawl when the component is aligned with the feature. Additionally, the component is configured to restrict angular movement of the key-cylinder with respect to the door, when the key-cylinder is forcibly manipulated thereby causing the component to contact the inner structure.
