A vehicle includes a door with an interior door cavity, as well as a lock rod and another item of a locking system, an impact beam, an attack member and a push member, all housed in the interior door cavity. The impact beam crosses the other item from laterally between the other item and the door. The attack member faces the lock rod from laterally between the door and the lock rod. The push member, along the impact beam, faces the other item from laterally between the other item and the door and laterally beyond the impact beam. When the door collapses when compromised by a side impact event, the door carries the attack member for attacking action on the lock rod. The door additionally carries the push member for counterpart pushing action on the other item. A connection between the lock rod and the other item thus breaks.
