This is one of those ingenious products I wish I had thought of… a place to keep things like spare keys and emergency cash incase you are travelling and get locked out of your vehicle.
It does come with a cover that goes over top of the opening with the combination, so no one would see that there is a combination lock there unless they took the hitch cap off… and why would anyone do that?
It is super easy to set or change a combination with the reset screw inside of the drawer. So you can change the combination at any time in the future, so you could also use it as a way to leave money or items for someone when you aren’t present, just give them the code.
This isn’t waterproof, so I wouldn’t leave anything paper based in it longterm, at least not without also sealing it in plastic. It might be fine in dry climates, but be aware for those in snowy or rainy climates.
