Usage
Designed for high-security access control, the Cisa TEKNO double half-cylinder is intended for external and internal doors where advanced mechanical protection and controlled key duplication are required, such as in residential, commercial, or institutional buildings.
Advantages
- 10-pin (6 active, 4 passive) key bitting system resists picking and unauthorized duplication
- BKP anti-bumping patented technology enhances resistance to bumping attacks
- Cemented steel pins and hardened drivers provide drill protection on both sides of the cylinder
- EN 1303:2015 certified with a durability rating of up to 100,000 cycles
- Standard clutch mechanism allows operation from both sides even if one key is inserted; minor drawback: only compatible with keys provided by CISA Tekno Centres or authorized dealers for additional security copies
Specifications

- Durability & Certifications: Certified under EN1303:2015 (Durability Level: Grade 6 – up to 100,000 cycles); conforms to SKG** requirements[2][5].
- Performance Data: Resists pulling/tearing thanks to special cuts on body/plug; anti-bump (BKP patent), anti-drilling via hardened components[1][5]; operates from both sides due to built-in clutch.
- Differentiating Features: Controlled code card system restricts unauthorized key copying[1]; flat reversible ergonomic key with plastic bow for comfort. Cylinder measures (30/10 mm variant): length approx. 39 mm overall. Supplied with three original keys plus security card per unit[1][5].
How it works
The user inserts an authorized CISA Tekno flat reversible key into either side of the cylinder. The advanced bitting system engages precisely aligned pins within a dual-row design. When properly aligned by the correct key, it permits rotation of the lock cam to operate connected door hardware securely from both sides—even if a second authorized key remains inserted on the opposite side.
