I first had a basic Master Lock key safe, the type that you have to scroll the numbers and align them. That turned out to be disastrous.

My airbnb guests were struggling to get the lockbox to open. It wasn’t clear if you aligned the numbers face on, or slightly lower or higher, and sometimes the box just wouldn’t open. Also, some of the airbnb guests would leave the correct numbers on display, so in effect the box was always open.

I soon enough realised that this was certainly not a safe solution, also, it seems that there are videos on YouTube showing you how you can crack the code, by gently rolling the numbers till you hear a different slight clicking sound.

The cavity was awkward, the keys would drop in the box in a way that made it difficult to close the box, I had to use a magnet sticker at the back of the box.

So then after extensive homework, I bought the 5441 digital masterlock from safe.co.uk

Their prices were the most competitive, and their service next to none.

This lockbox literally addressed all the issues I previously had, and improved the experience even more.

The lit up numbers are easy to press in, you wait for the sound that the box has unlocked, and you pull it open. You can set the amount of time that the box can stay open before it locks itself again.

There is an activation code unique to the lock box on the top corner of the flimsy instruction paper, and I would advise any new owner to copy that number and keep it safe, in case you lose the paper.

Once you have lost it, no one will be able to retrieve it for you.

There is also a primary code, a back up master code, and up to 5 secondary codes.

All these numbers will unlock your box.

You have to have downloaded the program to your phone, and have the phone and the box in each other’s vicinity to set these numbers initially to work with each other via bluetooth.

Once fixed in situ, you can either unlock the box by bluetooth if you’ve got the program downloaded and are very near the box, or if someone gave you any of the above numbers, you just key them in.

But where this product really excels, you can create a temporary code remotely, as long as you’re connected to the internet, so you can theoretically be in a different country, and create an access code, that you can email or text.

The temporary code will be created by the app randomly, and it is not necessary to be near the box.

This temporary code will work only for between 4 and 8 hours, you get to choose a start time.

This will work if you are sure that your guest will have access to their phone when they arrive.

It is also very handy if you want to allow tradesmen to come in in your absence.

We have found this to be the best way for moving forward, feeling secure that we have our own access codes, our guests don’t need to download the software which is complicated to use for some, and no temporary code will repeat itself.

It is of course a good idea to send another temporary code to the guest on the day they’re leaving, if you wish them to replace the key in the lockbox, if no other arrangements have been made for leaving the key.

Since we've installed these boxes 6 weeks ago, they have been a game changer. Go get it!

The Key Safe 5441 is a superbly designed and engineered product. It is solid and sturdy and of a much better construction than other similar products. The app that it uses is cleverly designed and has the ability to issue temporary access codes which can be easily revoked after use. We had ours professionally fitted by a joiner who commented that he thought it was the best key safe he had ever seen and fitted. Although the full functionality of the app takes a bit of getting used to, it can still be used as a simple safe without using the app on your phone. Highly recommended.

Excellent. Overcame the problem of being unable to see key pad at night and so far has been reliable. Find app a little difficult but this may be age related. A good buy even if a little expensive.

This is the perfect key safe for renting out our caravan. I can log into the masterlock app which is linked to my safe only, and get a temporary code that will only last 8 hours before it changes, and then email or text that code to the customer to retrieve the keys upon arrival. I can then send another temporary code for when they are due to depart.

Using temporary codes for this purpose is great because I don't have to worry about customers helping themselves to my caravan without paying when it is unoccupied.

Being able to connect to the safe via Bluetooth is a good feature, you can set a number of permanent codes and are able to see when the safe as been accessed or attempted access and which code was used.

In my opinion this is a great safe.

We have been using this key safe for 3 months now, to facilitate carer access for an elderly relative. It has performed perfectly. It is easy to set up and install. Feedback from users has been very positive. The keypad is illuminated and the buttons are easy to press - no more broken nails apparently (unlike a previous key safe!). The other great feature is that every time the safe is accessed by bluetooth, all the previous access times are logged in the app; this has proved useful for keeping track on access. Overall, this is an excellent product that I would recommend.

J could give this keysafe 10 x 🌟

I bought it for managing my holiday let business. My previous keysafe had to have the code changed manually. This one can generate a random code for every guest which times out after a few hours. I can text the code to the guest to start for Entry time and expire a few hours later. I can then generate a new randomd code for Exit day a few hours in advance of alloted Exit time which expires at agreed exit time.

Once I had the right app, I have never looked back. The customer service were as helpful as they could be. There is a business and residential app. I hadn't been aware of this and had installed the wrong one.

Being able to send a temporary code to workmen and guests while I work away gives great peace of mind.Worth every penny.

Great product, perfect for my Airbnb apartments. Easy to set up and install. Plenty of room in the safe for apartment keys. Light up display makes it easy for guests to access the safe at night. Easy to issue access to cleaner via app. Definitely worth the investment in my view.

It is easy to install and gives great control over access. It feels well built and safe

BUT....

You really need to put together a short, simple guide on YouTube showing the guest exactly what they need to do. Some people find it very confusing (especially when the verification code take hours to come through!). It would be so good to say here's your invite and here's a link that shows you what to do !!

I’m really impressed with this safe; my mum has rheumatoid arthritis and cannot operate anything that doesn’t have buttons on so she is very pleased with how clear and straightforward the buttons are. I take care of managing the App and mum loves the simplicity of operation, so it’s a great buy all round.

Good product let down by poor software, difficult to send codes due to a lack of response from the server end via email. Works better using what's app.

Smart design, ample storage and the ability to use without a code via your mobile is great. just the set up with the software which needs improving.

Great product, easy to use and set numbers for guests.

One point that would make it perfect is that the box could be a little more generous with space for the keys, or have some way of hooking keys to the back.

Does this box alert or lockout if multiple incorrect attempts are made at the 4 digit pin?
Are alerts sent for incorrect pin attempts?
Andy Bonnar, Bathgate
After 3 consecutive unsuccessful attempts using the lock box keypad with less than 1 minute between attempts, the lock box will not accept entries for 1 minute. The unit can be unlocked using an authorized Bluetooth enabled device. This Tamper Alert will be viewable in the lock's history the next time it communicates with an authorized device.

How far can you be from device to remotely open it? For example could I open it from abroad?
Bronte Watson, Harpenden
You would need to be in range for the Bluetooth on your phone to connect to the lock meaning the range would be in meters rather than remote access from abroad.
