Easy to use and install. Should have a magnet in, so the keys will not fall out when opened

Suitably small so as not to be intrusive or obvious outside. Numbers on key safe could be larger of different colours for easier reading

With numerous Carers and family members requiring access to my totally disabled bedridden sister at all times, provision of individual keys presented a problem. However, thanks to your wonderful Master Lock Mini Key Safe the problem has been resolved without compromising security of my sister's home. Many thanks for a great security product, best regards, Dennis Wetherell.

A first class product. We mounted it in our pump room slightly out of the weather. Fitting was straightforward into a concrete wall, Build quality is very good. On three occasions we have made use of it's facilities and it's saved us a load of frustrations, especially at 2am in the morning! once you have dialled in the correct code it opens easily. We have no problems with storage as we only put two keys in the box. In brief a first class product. I would say that as for value for money it is not too expensive; after all how many of this type of product do you buy in a lifetime?

Secure and safe way of storing spare keys. Have used once or twice already. Not sure whatissue issues are relating to house insurance / contents cover issues are when purchasing item. That would be useful, ie insurance companies view etc

Definitely good build/value. Realistically only takes one key and definitely not with the free fob that came with it! Security? Who knows. No-one has tried to break it yet — fingers crossed! Despite that, definitely recommend.

Easy to order from online description, easy to find the correct size for my requirement.

My order arrived quickly, as promised, was as described. The instructions for installing were easy to understand and installation was straight forward.

It was simple to set the security code from the instructions provided.

I would recommend safe.co.uk to anyone looking to buy a lock box.

Switched to this after having a much more complex one which was battery powered and linked to WiFi, but when the batteries failed, I needed to be physically there to unlock via Bluetooth and as it is a holiday let, this just did not work for me. This one is so much simpler and no issues so far.

robust sturdy weatherproof ( it has survived a storm already!) I have artritis and find it easy to use. Installed very quickly by a very unskilled DIY in-expert thanks to clear instructions provided! Holds a full set of keys. I had questoons about suitabiloity- a quick call to customer servoces helped me foind this one. I think it offers really good value for money. Would recommend and would purchase again

It’s great for what we wanted. We can get two keys in quite easily. The lock seems safe and secure. I find it a little tricky to push the button down once you have changed the numbers to unlock.

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.

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
