The CISA C3000 0N116 cylinder pair is a reliable solution for upgrading surface‑mounted locks in residential and commercial environments. Made of nickel‑plated brass, they ensure durability and mechanical strength. The C3000 system uses a protected traditional key, with duplication allowed only through the Security Card, ensuring controlled key management.

These cylinders offer key security grade 6 and bumping‑resistant technology, developed by CISA to counter non‑destructive opening methods. Internal components are engineered to resist forced entry attempts.
