A cylinder – from start to finish
The CESrelock building cylinder remains permanently fitted in the door. No need to replace it, no hassle. A solution for the entire life cycle.

The temporary access key allows access during the project and automatically becomes invalid after handover, as soon as the user key is used. This saves construction companies time, money and materials, and ensures that future residents feel safe right from the start.
With CESrelock, lock cylinders remain in the door even when tenants move out. New tenants simply receive the next generation of keys, which automatically deactivates the previous set. This saves time, money and materials, and makes key management in residential complexes significantly more efficient.
