Gives me a sense of safetyWorks pretty good. Best for only 1-2 flat keys. After some good use, the spring on it broke. Still works but takes a bit to open the door.Quality item. Satisfied with purchase.Box is much heavier and sturdier than I thought it would be. Very happy with purchase and highly recommend.Like the qualityI mounted this on the interior wall of our garage, where I could keep 9 master key backup. This box isn't designed to hold more than about 4 to 5 keys, but I wanted to keep them all in one spot without spending $30+ and getting a much larger box. (Most of the larger boxes hold 20 or more and that seemed unnecessary.)Anyway, as is typical for these small key safes, the interior dimensions are pretty small, and are not designed to hold that many keys. However, I was able to put 9 in there by doing two things:1. I put each key and its associated name tag on a bit of silver ball chain. You could also use very small, thin split rings.2. Put all the keys into a small Ziploc SNACK SIZE bag (not a sandwich sized bag) and fold it as flat as you can before putting it inside the box. Be careful to keep the top as clear as you can, as not to get in the way of the locking mechanism. Works like a charm!This box was very easy to mount to the wall. Just mark the holes, drill pilot holes, tap in the included anchors and screw in the included screws. I was done in just a couple minutes and it feels very solidly attached.I have several of these. Nobody messes with them.I have a couple of these lockboxes but I bought this 1 from this company because of the different color options. The lockbox was working great for 6 months and then1 day it stopped working. The reset button got stucked. I contacted the company and they try working with me to get it fix but nothing worked so they sent me out a new replacement which I appreciate so much as I used that keybox everyday. Great company to buy from and great customer service.
