This new-generation product,
based on Mul-T-Lock's telescopic pin technology,
features an innovational locking concept.
The new system consists of complementary mechanisms that operate independently while enhancing one another: a set of 5 telescopic pins, an extra locking bar with 5 finger pins, and the Alpha Spring, a patented moving-part located
at the tip of the flat key, increasing key protection against duplication and manipulations.
With the sidebar and the moving-part,
this new mul-t-lock cylinder seems to be bump-proof,
which was necessary as a video show us that
mul-t-lock Interactive has been bumped-open during a test
