Master and Restricted Key Systems

A legally restricted system to protect every key in your home or business from illegal duplication


Gemini specialises in master key systems for hotels, landlords, HMOs (house of multiple occupancy) schools, colleges, local authorities, large domestic properties and commercial businesses.

Controlling your security needs in Bedfordshire

Gemini Lock & Safe can offer master keyed systems that include euro cylinders, oval cylinders, rim cylinders, padlocks and cam locks. Imagine 200 houses, 1500 rooms and just ONE KEY for the landlord! Sub master keys and service keys for maintenance personnel to grant access to the areas they need without access to customers or private rooms or areas!

Different keying arrangements can be adopted for any situation, giving you control of key security in virtually any environment. All of our master key systems are unique to each customer, with a unique system number without any possible duplication. We can build thousands of unique locks all under one master key if required. Tenants keys can open communal front/back doors and their own room, cleaner keys just open main communal areas, sub master keys open everything at that address. Your grand master key will always open everything!
