Multi-step security verification

An overview of special functions

Interaction between precision locking elements
The profile system features special security functions that are specifically designed to work in tandem. Several additional sensing elements within the cylinder check the profile geometry and structure, significantly enhancing the level of security. Supplementary locking functions provide reliable protection against tampering and forced entry.

Authentication elements for high-level copy protection

Inside the cylinder, four additional pins check for undercut and interruption. Together, these two features enhance the level of security.

Lateral coding

Up to four horizontally mounted control pins are integrated as further safety-critical features.

Drill and pull-out protection

The optional drill and pull-out protection provides greater protection against the cylinder being forcibly removed.

Personalise cylinders and keys

Easier than ever before

Personalise your locking system and turn it into your calling card. Whether it’s a custom-designed key or a personalised cylinder – CES offers specialist partners a wide range of options for visual and functional customisation. This results in solutions with high recognition value that combine security, brand identity and professionalism, and clearly stand out from standard solutions.

Mechanics meets access control

The transponder clip allows CES’s mechanical profile systems to be easily combined with CES’s electronic locking systems and the AccessOne access control system. This creates flexible hybrid solutions that combine mechanical security with electronic organisation. Existing locking systems can be expanded in stages and adapted to new requirements without any disruption to the system and with maximum planning reliability.
