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.

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.

Wow! I have been waiting for a robust and secure key safe that can be managed remotely for some time now, this does what it says on the packet!

Although it took some time to upgrade the lock so that it could be used on Masterlock Enterprise, the wait was well worth it. I now have complete control of my remote buildings, now know who has accessed and when, and can provide someone with access when calling unannounced.

The software interface is easy to use, the lock is easier - but I would like to see it slightly larger for those once in a while larger bunches of keys.

A fantastic product, very pleased with the purchase.

On the face of it, this is a very well-built product. However, I am a little concerned that its security capability could be compromised - according to a YouTube review of this product, the plastic covering on the front panel can be easily cut away to reveal 2 cross-head screws which hold the locking pins. It seems that once exposed, the screws can be easily undone, thus facilitating the easy opening of the unit's door :-( I haven't validated this but it is of some concern to me. Other than that, it is very easy to use and far superior to most other similar mechanical key safes. The ability to assign a number of access codes is also a useful facility.

We love the, we now have 6 across our properties. They are secure, easy to install and set up. The best (and affordable) solution on the market - in my opinion.

The battery life (something I was concerned about) is brilliant and I don't think I've had to change one yet! And considering our level of use, that is quite amazing.

Possibly the best feature is the distant to open in the App - no need to remember multiple override access codes!

I wish the storage was fractionally bigger, but other than that it is great.

Wish there was WIFI enabled version, I would buy that in a heartbeat!

Standard Key Safe Installation

We offer professional installation on our complete range of Key Safes.

Our experienced engineer will complete a brief site inspection and then discuss their findings with you to agree positioning of your key safe.

Your installation will include fixing the key safe to an exterior wall using the fixings included with your key safe. The fixings are designed for use with a solid surface such as brick or concrete.

The position of your key safe will be governed by safe site access, and other obstructions such as submerged pipes or cables within the wall.

The engineer will carry out a final assessment to ensure the key safe is secure before providing a brief demonstration of your key safe and confirming the installation has been completed to your satisfaction.

Non-standard Installation

In some cases, it may be necessary to install additional materials or provide extra resources (manpower) to facilitate an installation in a safe manner.

If additional costs are likely these will be discussed with you prior to installation. Reasons for extra costs might include:

  • Specialised access equipment and permits such as hoists, lifts and cranes.
  • Outside of normal hours working (Mon-Fri, 9am to 5pm).
  • 4x4 Vehicular access requirements to remote rural sites.
  • Road closure including necessary permits.
  • Additional manpower to overcome technical, lifting or safety access issues.

We offer installation throughout the UK mainland, however some more remote and rural post codes in the Highlands are subject to a surcharge to cover additional fuel and traveling time costs.

The following areas will incur a rural travel surcharge:

£55.00 Surcharge Areas

  • PH 1 - 26 (No coverage in other PH postcodes)
  • PA 1 - 19 (No coverage in other PA postcodes)
  • KA 19, 26
  • ML 11, 12

£105.00 Surcharge Areas

  • IV 01-17, 30,31,32 (No coverage in other IV postcodes)
  • AB
  • DD
  • TD
  • DG
  • KW

These additional elements are deemed to fall outside the definition of a 'Standard Installation'. If you feel your installation might be non-standard please contact us to discuss your individual requirements.

If applicable, additional costs are to be paid before installation begins.

Warranty Terms & Conditions

Our installer provides a standard 12 month warranty on all new installations and a 3 month warranty on all materials provided during maintenance visits.

Note: Existing system components and pre-supplied equipment are not included in the installation warranty as these elements are covered by the Manufacturer warranty.

We reserve the right to undertake an ‘Assessment Call’ without prejudice to investigate any complaints relating to materials failure or poor workmanship to assess if the complaint is valid. Please note that remedial service calls generated by elements outside of our sphere of influence or due to different fault conditions will be chargeable to you at an agreed call out charge.

In scenarios where you request a post installation service call and our assessment identifies the fault condition or cause of the fault falls outside of the limitations of the standard installation warranty (Force Majeure, different fault etc) a call out charge will be incurred for the visit.

Assessment calls raised for reasons outside our sphere of influence or responsibility and not covered by the standard installation will incur a call out charge for labour and additional materials.

The following are examples of when a call out charge would be incurred:

  • Accidental Damage
  • Malicious Damage
  • Materials or Manufacturer Failure
  • System Modification
  • Incorrect User Diagnosis
  • Broadband Related
  • App Related
  • User Error
