Master Key Systems

Master Key Systems from Keyprint

A master key system is a key plan whereby selected keys can open a number of pre-defined doors. It helps maintain better control, saves key replacement costs and is convenient, as there are a lower number of keys in circulation. It also provides quick access to all rooms within the premises, e.g. for security staff and management personnel. This is not only convenient but can save lives in case of emergency. For over 30 years, Keyprint have provided a fast and reliable in-house master keying service and can assist in specifying a suitable master key system to ensure that a system meets your clients' security, budget and functional requirements.

System Specification & Overview

When designing a new Master Key suite, it is important to consider the following factors:

  • Where is the new Master Key suite to be installed? e.g. Residential, Office, School, Hospital etc.
  • What level of security and protection from common attack methods is required? For example, does the client require Anti-Pull plugs, or hardened pins to provide additional resistance from drilling?
  • Does the client require an open section to enable local key duplication or restricted keys that require a letter of authorisation?


  • A system specifically designed to suit your needs, regardless of the type of building, e.g. residential, commercial, small, large, complex, etc.
  • A multitude of cylinder options to fit your security, safety, aesthetic, regulatory and budget requirements.
  • We also offer fully integrated systems that include both mechanical and electronic components that can be operated using a single key, with proximity cards and key fobs available for secondary key holders to operate areas that contain electronic cylinders, proximity readers or pin-code readers, enabling the end-user to control access through time slots and provide temporary access when required.
  • Some of our systems include options such as classroom functions for schools, anti-ligature furniture, DDA-compliant thumbturns and accessories. 
  • We offer both open sections for systems where key blanks are available on the open market and patented designs, which restricts the availability of copy blanks to ensure a higher level of security.
