Very bad design, I've already bought a similar product for the car and they seem to have the same problem, the key cover doesn't want to move, in winter it's terrible to open the fuel cap. I wouldn't buy it again if I didn't have to. It's better to fix this than have someone climb into my tank. I think it would be pretty easy to get in anyways, I think I've seen a few videos of people using flat heads to get in but better with one than without.
