Hidden Hitch Key Hider Keep a spare key securely hidden on your vehicle without using a magnetic box or leaving it somewhere obvious. This hitch-mounted key hider slides directly into a standard 2 inch receiver hitch and provides a concealed internal compartment for storing vehicle keys, house keys, or other small emergency items. The low-profile design keeps the storage compartment tucked inside the hitch receiver, helping protect its contents while keeping them out of sight. Simply load your key, slide the hider into the receiver, align the hitch-pin hole, and secure it with a locking hitch pin. This design features a large hidden compartment for modern large key-fobs. Storage area: 5 ½ x 1 ½ Important: A locking hitch pin is required to secure the key hider and is not included.
