What are Anti-Snap locks and how do they prevent Lock Snapping?

An anti-snap lock maintains the same profile as a euro-cylinder lock, however has defensive measures in place to prevent illegal access through lock snapping. To do this, Euro Cylinder anti-snap locks are manufactured with a line carved along the first quarter of the cylinder, encouraging a lock to snap at this point, rather than the midpoint, if it were to be snapped illegally. This line prevents any further manipulation of the locking system.

The Anti-Drill function ensures (by means of hardened pins within the cylinder), that a drill is unable to penetrate the keyway again preventing illegal access. Anti-Pick ensures that a locksmiths pick in the wrong hands are not able to manipulate the operating pins.
