Review: Solidly made with clear instructions - I was worried that it would not fit my doorknob-older house. It did, but surprise! I couldn’t close my door with the key safe on it. That never crossed my mind, or if I would I be able to close my screen door with the key safe in place. I never did find that out because the second problem was that I couldn’t close the key safe with a key in it. I took it on and off, multiple times, got it working with a key in it and have put it on a different door. I don’t want to fiddle with it now. It’s working and fine where it is. I am not moving it. It’s easy to set or change the combination, and except for getting it to close with a key inside, it has been easy to install/operate. I feel safer with my spare key in this quality Master Key safe. It’s very sturdy and my key is going to be accessible only to me. It’s not going to be easy for a thief to open it. I think my problems closing it were due to me, and not due to any problems with the key safe.

This is a very sturdy lock. Very nice appearance, even though you'll want to secure it to a pipe or something low to the ground. It works great and looks even better.
