Patented Key Cylinders

Master key systems provide a flexible and secure method of access control by enabling a single key to operate multiple locks, while still allowing individual keys to access only specific doors.

Next level controlled access

This hierarchical structure ensures that different levels of users, such as facility managers, staff, or residents, can be granted appropriate access without compromising overall security. By organising access in tiers, master key systems simplify key management, reduce the number of keys required, and improve operational efficiency across a site.

We have partnered with Codelocks, to enhance our “one key for all” approach. Selected Codelock products are now compatible with CES high-security patented cylinders, combining advanced access control with robust mechanical key security in one streamlined solution.

This integration offers both convenience and increased physical protection, while expanding suitability across residential, commercial, public, and large-scale facilities. The result is a flexible, scalable access control system designed to meet modern security needs.
