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.
