It never fails: you drive into a parking lot and a sign warns you not to leave your valuables in the car. Well, maybe you're going swimming or jogging or something where you don't want to tote your purse/wallet/etc. with you. What then?
Perhaps the solution is the Hitch Safe.
This tiny safe slides into any standard 2" hitch receiver, so your car/truck/SUV/van may already be ready for the gadget. It's secured via two bolt retaining bars inside the Hitch Safe. The hitch receiver already acts as a solid steel vault, and the safe offers a way to lock it up with a secure combination entry.
While the little automobile safe isn't exactly going to be roomy, it offers space enough for spare car keys, cash, driver's license, and credit cards, so it may be all you need.
You can purchase the HitchSafe Key Vault for $70 at Amazon or look for it at your local auto shop.
