Anti-Snap Locks

Lock snapping is the most common forced-entry technique used against uPVC and composite doors: a standard euro cylinder can be snapped and the door opened in under a minute. Anti-snap cylinders — look for TS007 3-star or Sold Secure SS312 Diamond ratings — are engineered to break safely and resist the attack.

Swapping cylinders is quick and affordable, and is the single most effective upgrade for most modern doors.
