Review: Great product - Brilliant product. Been using for 3 years now at an Airbnb and has not let me down once or not yet had to change the battery. Easy to install and operate and to change numbers. Works with an app too so you will never forget the numbers. Super sturdy and secure and would need a proper work out with metal cutting tools to break in. Only thing is that the space inside is quite shallow and if you have a bunch of keys 5 or more they won't fit in easily. I had 2 other safes before this one and both let me down within a month so im super happy with this one.
Review: Think carefully before purchasing this key safe. - We purchased this key safe back in Sept 2022, the date today is Aug 2023. The key safe was easy to install but somewhat a little tricky when trying to connect up to the phone app, eventually after many tires, we managed it and got the key safe working as intended. We purchased this key safe for the sole purpose of storing a key which would allow care staff, emergency services, community nurses access to my fathers property - he has very poor mobility and it's not always possible for him to get to the door. After installation, everything worked as intended, all the different services had their own number and all was good. However a couple of weeks ago (14th Aug 23), I received a phone call from the care staff, they could not gain access, the key safe was not opening. Naturally, I thought the battery might be low so I head round with a 9V battery to place on the emergency terminals at the bottom of the key safe and open it with my primary code, and a new battery to replace the old one within the unit. But when I arrived, the battery was not low, and the 9V battery I had to jump start the key safe made no difference, the key safe just did not want to open. Normally, you enter your code, the circular button turns green, there's a 'click' noise which indicates the mechanism has unlocked and you can pull the door open. What was actually happening was - Code was entered, light goes green, NO CLICK, door won't open. Even with the 9V battery attached, NO CLICK, door wont open. At this point, I started to become concerned, of course we have spare keys, but no other mechanism to externally store them securely on my fathers property. I tried to contact Master Lock to obtain some support - well I can tell you after a week I've had no email response from Master Lock and when you call the UK number, you can only speak to an answering machine. Their phone system states they are open Monday to Friday 9am to 5:30pm, however their phone system does not allow you to leave a message until 9:10am. A day and a half goes by after the initial call from the care staff not being able to get the key out, at this point I've tried opening the key safe 15 to 20 times with no success, I was about to take a hammer to the key safe to obtain the key and replace it with a different brand, but my other half insisted I tried again, so I did. This time, the key safe sprang into action and opened - I was gob smacked!! I take the key out and close the door to the key safe, I re-enter the code and it opened!!, I go to close the key safe door, but I cannot, the door won't close, so I re-enter the code and the light goes green, but I cannot close the door and there was no 'click' noise. So now I'm thinking that this unit is faulty because it's just throwing random problems - not being able to open it for a day and a half, now we cannot get the door closed. To summarise, I don't have confidence in this key safe, I work for an NHS ambulance service within the UK and I DO NOT recommend this key safe, Master Locks support is shocking. I will be replacing this key safe regardless of its current working condition with another brand, more likely a mechanical lock also.

### ⭐⭐⭐⭐⭐ Security and Peace of Mind in One
*by K***V on 8 June 2019*

This is a great keysafe. Very sturdy, easy to use and discreet. When it came to installation and setup, the most difficult part by far was extracting it from the packaging (It was screwed into the packaging inside the keysafe - took ages to work out how to remove the package). It fixed to the wall really easily and setup was very simple. I love the flexibility it gives with the app; being able to have a separate code for our cleaner is great. The temporary code feature is also really useful for somebody who only needs one-time access - no need to keep changing the code. The App is easy to use and gives information on when the keysafe is used, so you know exactly who has accessed it, and when. The light-up keys are brilliant, meaning that you never have to struggle to see the numbers, even when it's dark. All in all, a great product. No need for multiple keys (and remembering who has them). Would definitely recommend.
