How to choose the right cylinder

These decoders use the technique of a lock profile, i.e. replicating the position and depth of the pins inside a lock cylinder with tool that has yielding elements aligning to the pin depths.

How has CISA addressed this? By adding a new, specially shaped pin into the cylinders. This limits the effectiveness of the decoder, preventing cylinder opening.

This technique involves striking the pins in such a way as to move the respective drivers and clear the shear line.

How has CISA addressed this? Some cylinders feature the patented BKP Bump Key Power driver, while the RS5 and RX radial cylinders feature an innovative patented telescopic driver.

This technique involves using a tension tool and a lock pick: with the correct tactile feedback, the pins and drivers inside the cylinder can be set at the shear line.

How has CISA addressed this? By inserting special patented drivers into cylinders to counteract lock picking.

This technique consists of attempting to extract the cylinder by breaking it using pincers or other tools.

How has CISA addressed this? Some cylinders feature the Snap Resistant system (a steel core that runs through the cylinder), others have a pre-cut for controlled snapping; in some latest-generation modular cylinders, it is the screw that provides protection.

The drill break-in technique consists of attempting to drill through the cylinder, causing the pins to fall out or break and thereby open the lock.

How has CISA addressed this? By installing carbonitrided steel pins or protective steel inserts.

For cylinders with patented keys, duplicates are conditional on presentation of the ownership card supplied with the cylinder. This prevents unauthorised duplicates.

Clutch-system cylinders allow the cylinder to be opened from the outside, even if the key is inserted on the inside. This feature is useful in emergency situations (if someone inside the house is in difficulty) or simply for convenience.
