SL-590 Punch Button Lock Box - Secure Wall Mount Key Storage Safe for Homes, Offices & Rentals | Outdoor Key Hider for Airbnb, Vacation Rentals & Property Management

I am really happy with this. I like to ride my bike to work everyday and I go out through the garage. I used to have to keep the garage door remote in my bag when riding (a sports bag). However, it got old having to fish it out (especially when your hands are cold and you got on gloves) and open the garage or (even worse) getting ready to go and the bag hits the bike saddle and the garage starts opening again... I looked at getting the remote garage door openers that have a code and go on the wall, but they were expensive. So I got this! This was pretty cheap (about $20) and worked perfectly.I first got the MasterLock one that is similar, I was hoping it would work since it had a spin combination that required the combination to be entered in sequence, but it had such a large locking mechanism that it would not hold the garage door opener (would not even hold a car key). So I got this, it was my second choice, but it is super nice!This is solid metal and feels solid when you are holding it, it is also pretty heavy. The inside dimensions are a nice size and I can easily fit an emergency house key the garage door opener and have some room for a few other keys.It is pretty easy to setup, I did have to read the instructions and would not have figured it out otherwise, you have to use the little plastic key thing to unlock the numbers that are allowed to be entered to unlock it. You can enter more than 4 numbers but for security you should stick to 4. Once I had it setup I used the included screws to mount it to the wall. The screws did the job, they were a little soft, but I put a starter hole (in thick wood) with a drill bit and they went in and a little force got them all the way in. The unit feels secure on the wall!The unit is mechanical, so it just requires the 4 numbers to be entered in any order (it essentially locks them down until the reset is hit or the open is pushed down), so you would not want to use more than 4 or it would be easier for someone to guess the numbers.The unit does lock as soon as the unlock piece is released, so you either have to hold it while you have it open, or just put the code in again when you get ready to close it (this is what I do).I do have the unit under the garage edge but it still gets wet. I have not had any issue with water in the unit or humidity. The thing is not waterproof so heavy rain could wind up getting inside. Where I live it hardly rains and when it does it is a mist or light rain, so this was not an issue.This thing is very sturdy and feels secure so I think anyone who attempted to get it in would have a hard time (with the right tools you can get into anything), but the normal thief will not be able to get into this, so I am happy with it. Plus the issue of the combo guessing it not too much of a concern, since it would take them a while to guess it (luck) and hopefully someone would question why some random person is behind my garage; truthfully, if someone wanted to get in, it would be best to just pry it off the wall and take it with them to drill open. However, I do not see that happening, and again someone would hopefully question why someone is prying something off my garage.In the end this does the job and worked exactly as I wanted it to. If security is your primary concern, this is not the best option, but really, nothing in this category would be. This is secure and can hold a lot more than the competitors!!! I am happy with this and this makes my life much easier (plus it holds an emergency key if we get locked out, much better than hiding it under the mat!).
