The Williams Key is an emergency tool used by First Responders to gain quick access to buildings and houses. The purpose of the tool is to toggle the strike of a lock without doing damage to the lock, door, or frame. It works well on Gates with anti-vandal plates, Elevator Control Rooms, Commercial Utility Doors, and many other outward swinging metal and wood doors. There is also a heavy-duty shove-knife built-in to allow for the piercing of wood trim on the frame of a residential inward swinging door. This is a handy tool to keep on any First Responder Vehicle or in your EMS box.
