On opening the cylinder, you can remove the key. However, the same matching key is required to lock the cylinder.

This function is only available for push cylinders. When the lock is opened, the cylinder advances and you can remove the key. To lock, just push the cylinder: there is no need for a key.

 Forced Locking

You can open the cylinder. The "Forced locking" function prevents you from removing the key. You must lock the cylinder with the key before you can remove the key.

The change code cylinder offers up to three locking configurations with one configuration active at a time. The end-user can change the lock to work with a new key without removing the cylinder from the lock case.

Pulling protection prevents attempts to pull the core out the cylinder housing. At the same time, these cylinders have an integrated ABS Drilling Protection and are thus compilant with extremely stringent security requirements.

 Drilling Protection (ABS)

Carbide inserts protect the cylinder against attempts to drill it open. ABS is offered single sided by default, but is also available for both sides. Drilling protection Fasif 1 is supplied by default with the KESO systems. Additionally, KESO offers additional drilling protection for enhanced security.
