The CISA C3000 0N150 cylinder pair is designed for CISA surface‑mounted locks and provides a reliable security upgrade for residential and commercial doors. Made of nickel‑plated brass, these cylinders ensure durability and mechanical resistance. 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. The 0N150 model follows the standard configuration of the C3000 surface‑mounted series and includes 3 patented keys with ALDE' profile.

Compatibility is specific to CISA locks designed for the 0N150 configuration. The technical structure matches the C3000 family, making this pair suitable for replacements and upgrades.
