Why choose CISA keys and cylinders

A wide range available for every need

The longer it takes to force open a door, the more likely it is that intruders will give up trying to get into your home. This is why choosing the right cylinder is essential.

CISA security cylinders are certified and patented against the main housebreaking techniques (Topolino decoders, bumping, picking) and are equipped with features that increase security, such as special steel pins, drivers and inserts, the Snap Resistant system and the BKP (Bump Key Power) system.

CISA’s wide range of models, sizes and characteristics covers all requirements, from the residential sector to commercial use, including in contexts where security, privacy protection and reliability are essential, like hospitals, clinics and school buildings.
