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 stil...

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.

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 solu...

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...

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

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?

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.
