Boost office security with a locksmith controlled restricted master key system

When it comes to restricted key systems we can design a system to suit a residential unit through to a multi story office or industrial premises. Restricted keying can, in most cases, be incorporated into the existing locks – an economical solution in tightening security.

So that we can accurately determine the extent of the installation we will visit your site to assess and discuss the various options and solutions available to you. If you would like to arrange a site survey please call us - we will send an experienced locksmith to your home or office.

We deal in mechanical and electronic restricted systems – key based or swipe card

Restricted key – A restricted key is a high security key that no locksmith will duplicate unless they originated the system and the person ordering a duplicate key is listed on the key registrar. At the inception of the system we create a file that includes the details of all persons authorised to order keys. In order to maintain the integrity of the system we will not cut keys unless an order has been put forth in writing. Restricted key systems are often installed when new tenants move into commercial premises. If you would like more information on starting a restricted key system please call us to discuss.

Master keying – A master key system is a tiered level of security that allows select people to access certain areas in a building. Master key systems are commonly installed by locksmiths in commercial situations enabling employees to move around in areas they need to access whilst keeping higher security areas out of reach. These systems are restricted in 99% of the cases, meaning that anybody trying to duplicate a key would only be able to do so with a written order from an authorised signatory. The locksmith who started your system will be the the only locksmith able to provide you with duplicates of the restricted keys. If you would like more information on how we can design a master key system tailored to your specifications please call us.

Restricted key systems provide an instant security upgrade

The main benefit of a restricted key system is that it allows you to take control of how many keys are out there.
