High Quality Key Cabinets From Thornhill

Thornhill Security Limited

Thornhill Security Ltd is an established security company based in Bristol, UK. We have over 40 years of experience in providing specialist key cabinets, safes and locking solutions for the domestic and commercial markets throughout the UK .

In addition to the sale of a wide range of security products including Safes, Vaults, Strongrooms, Access Control and Master Key Systems,  Security Grilles and Cages we provide expert advice and installation services on panic rooms, luxury safes and high profile security systems.


This is very much dependent on what type of keys are being stored. If the key tab is used correctly, you can store several keys on one hook without any problems.  For larger bunches we recommend using the Deep Key Cabinets/ Padlock Hook bars.

No, the cabinets are sent out on a factory set combination, which we recommend is changed when you receive the cabinet. Once this has been changed we have no way of retrieving lost/ forgotten combinations.

Please refer to the instructions that were supplied with the cabinet.

If the keys are hung in the correct way using the key tag, bunches of keys should not be a problem. It entirely depends on how many keys are in the bunch, what type of keys they are etc. We have cabinets that are designed to take bunches of keys by means of wider spacing and longer hook bars.

Yes, the cabinets are available Keyed Alike at no extra charge.

No, we do not supply the cabinets with any fixings as we do not know what type of wall they will be secured to, and the screws/bolts needed would be different depending on the wall.

If there are a large number of people requiring access or access to the cabinet is needed to be changed periodically. e Staff leaving, security requirement.  The combination can then be changed as needed.  With lots of keys in circulation, the security of the cabinet is greatly compromised.
