From a small guesthouse to a complete university campus, Holdfast Security Systems can supply a master key system to suit the most stringent requirements.

As suppliers of Master Key Systems to hotels, universities, office buildings and schools Holdfast Security Systems can design and create a master key system to suit any installation. Using in-house production we can also provide a rapid turnaround on locks and keys.

As all cylinder assembly and key cutting for our master key systems is carried out in-house, master key systems can be built up over a period of time, as and when existing locks need replacing. This reduces the initial outlay and spreading capital expenditure over several months or even years.

With locks and cylinders available from most major manufacturers, added together with electronic keys for those extra high security applications, we can tailor-make a system to meet any specification.

Traditionally keys from master key systems have been protected against unauthorised duplication by copyright. However with the change in the law regarding copyright protection older key systems are no longer proof against rogue keys being produced. Key protection is now only offered by patented key systems. Holdfast Security Systems can offer patented key systems to suit every application and budget from manufacturers such as Yale, Union, Mul-T-Lock, Abloy and Abus Pfaffenhain.

Case Studies


Problem: A sheltered housing development had no on-site warden but, as there was a warden call system, the main door could be released remotely allowing visitors into the building. When a resident had a fall the emergency staff could get into the hallway but could not get access to the flat without breaking down the door.

Solution: We provided a master key system whereby each resident carried a key that opened both the main front door and their own flat (but no one else’s). The master key was lodged in a safe that could be released by the warden call system, so that if an emergency occurred the ambulance or fire service could get into the building and obtain a master key from the safe to gain access to the flat easily and quickly.

Problem: A local university had a problem with keys being copied by students, giving them access when the buildings were closed up.

Solution: By introducing a high security patented key system we designed a master key system that allowed every building on the campus to have a separate master key with a grand master key opening every door. By introducing the system in stages we have built up a system of over 2,000 cylinders all operated by a single key carried by security staff. The patented system has removed the possibility of members of staff and students having keys cut without the knowledge of the security department.
