HitchSafe

The HitchSafe provides an much beefier and secure alternative to hiding your spare keys somewhere on the outside of your vehicle. It utilizes the thick wall construction of a standard receiver hitch to provide a safe-like armoured recepticle, secured by a four-tumbler combination lock.

The combination lock is protected by a dust cover that protects it from dirt and grime, but it would probably be a good idea to avoid submerging it in water or mud holes.
