How do restricted key systems work?

Master keying is a high-security solution commonly used for large-scale projects and commercial premises with multiple doors. A single key known as the "master key" will open doors within the building, and individual keys are designed to only open some doors. In this way, access is compartmentalised and can be restricted to restricted areas.

Your master key system is only as secure as the key distribution. So, how can you ensure that unauthorised people cannot duplicate keys?

Adtec Security Groups' clients are protected by rigorous security procedures. Restricted keys cannot be cut or duplicated without written and signed authorisation of nominated personnel at your orgainsation, and all the keys are safety coded to identify which company owns the system.

We specifically design these systems according to clients requirements with practically unlimited capabilities and combinations. Master key systems can be modified at any time to suit changing circumstances, for example, for new employees or business expansion.

Restricted master key system design & project management

Adtec Security Group will provide project specifications and collaborate with architects and builders early on to determine your master key requirements and avoid costly mistakes and modifications later.
A tailor-made maintenance program is developed to ensure that you are protected after the project is completed.
