Review: Good Box that Seems to Work Well - I bought this key safe box for my 91 yo father who has lost his house keys twice in the last 2 months. I figured that putting a key in the box outside his door was the best way to ensure that he'd never lock himself out. From the moment I received the box, I was impressed with it. It is heavy and has Bluetooth connectivity that allows it to be programmed from the Master Lock app. Plus you can download access logs to see exactly who and when used it. It can allow for several (I think up to 5 or 7) different access codes that can be personalized and assigned to different people allowing each person their own code and the ability to use their own phone to unlock the box via Bluetooth. It has lots of customization options and works better than I expected. The lighted keypad is a easy to see; the buttons are big and sound a tone and blink when you push them; and the ability to create long or short PINs is a plus. It feels sturdy and I think it would keep whatever you put inside it safe. I do have a couple constructive comments though... First, to open it, you have to grab it from both sides and pull on the flared edges of the door which folds down to open it. Though not a big deal, this would seem kind hard for someone with grip issues. I assume it's built like this so you can't easily take a pry bar to the key safe, which I understand, but it also makes it a little harder to use for people with disabilities or the elderly... Or if it got wet, it might just be a little hard to open for a regular person if it got slippery. Maybe if the door popped open slightly when disarmed, that would be helpful and make opening the door a little easier. Lastly, I have more of an installation tip than a criticism... maybe a criticism of the directions. When you install the Master Lock app and assign phone privileges to the app, make sure that you set the privileges for the app to access your phone's Bluetooth all of the time, not just when the app is running. I know this sounds strange, but I had all sorts of connectivity issues with the app communicating with the box when the app only had privileges when the app was on. The app would recognize the box but it wouldn't update it consistently with the new passcodes. It would download the access log, but I sometimes had a problem unlocking the box using the app. The app would see the key safe, but didn't seem to stay connected to it. The BT connectivity was very shoddy until I changed the apps privileges. Once I did that, the app recognized the box consistently and worked as designed. Unfortunately, I don't remember seeing anything in the directions about this tidbit, and there's no troubleshooting section in the included fold out directions to help you. The directions are poor and basic at best and barely helped you through the install process. Maybe if I had known how to set the app's permissions from the directions, my comments would be different, but unfortunately, that tidbit of info isn't there and so it tainted my experience until I figured it out. It was so bad I even considered returning the key safe as defective. Luckily I installed the app on my Android phone and noticed the "allow use all the time" privilege that I didn't see as a choice so I didn't select it the first time I installed the app on my Dad's Android phone. (My Dad has a Motorola phone, and I have a Samsung). Once I went into the app's privileges and fixed it, all the issues I had went away. Needless to say, it's working now and I think it'll provide the security that my Dad needs.

### ⭐⭐⭐⭐⭐ Simple to Install, Looks Extremely sturdy
*by S***Y on August 6, 2025*

This seems to be a very secure box. It is hard to grab onto to try to leverage off the wall. I found the app quite intuitive. I only have two suggestions. The product should come with instructions on which app to install. There is an enterprise app, and a home app. The former fills up the screen and you have to scroll to discover the second one. I recommend using longer screws. After penetrating the siding or stucco of your house, there is about an inch left to penetrate studs. I substituted 2 inch screws.
