Anti-Snap Locks
Lock snapping is a burglary method that breaks a standard euro cylinder in seconds. Anti-snap cylinders are designed to resist this. Upgrading is one of the most cost-effective security improvements for uPVC and composite doors.
Is your door at risk?
- Your cylinder has no kitemark or star rating
- The cylinder sticks out past the handle
- You don't know the make or rating of your lock
- Neighbours have had break-ins
How we solve it
Your locksmith will fit a TS007 3-star kitemarked cylinder, or a 1-star cylinder with 2-star security handles, or an SS312 Diamond-approved cylinder, sized so it sits flush.

Anti-Snap Locks: common questions
How can I tell if my lock is anti-snap?
Look on the face of the cylinder for a kitemark with stars or a Sold Secure Diamond mark. If there's none, it's probably a standard cylinder.
