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.

You should be able to fit the key in. **Q: Can the code be changed?** A: Yes, easily. When you open the keybox you slide a lever over and then change the combination to anything you want, then slide the lever back and you are done. So you can use the keybox at different properties and never have the same code. **Q: How does this work? Want to use it when I leave an elderly relative home in case fall alert is triggered.** A: It is a sturdy combination lock which you attach to the outer door handle. Give the customizable combination to your fall alert company, local emergency personnel, and other trusted persons. It works great ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solidly made with clear instructions *by K***N on May 13, 2026* I was worried that it would not fit my doorknob-older house. It did, but surprise!
