Anti-snap protection
An anti-snap cylinder has a sacrificial break line — under a snapping attack the outer section breaks away cleanly while the main lock body and cam stay protected and the door stays locked.

Anti-Snap Locks - British Standard High-Security Cylinders
If you own a UPVC or composite door, the most important security decision you'll make is the euro cylinder inside it. Lock snapping is the most common method used to break into UK homes, and a standard cylinder offers very little resistance to it. Upgrading to an anti-snap cylinder is one of the most effective and best-value security improvements available, and we fit them same-day across Wrexham, Chester, Shrewsbury and Oswestry.

Anti-Snap Locks FAQs
How do I know if my current lock is at risk?
If you have a UPVC or composite door and the cylinder isn't marked as anti-snap or TS007-rated, assume it's vulnerable. A quick look at the cylinder tells us, and we're happy to check on a visit.
Do I need a whole new lock or just the cylinder?
Usually just the cylinder. On UPVC and composite doors the security is concentrated in the euro cylinder, so swapping it is a quick, cost-effective job that transforms the door's resistance.
What does TS007 3-star mean?
It's the kitemark rating for snap resistance. You reach 3-star with a 3-star cylinder alone, or a 1-star cylinder plus a 2-star security handle. It's the level many insurers now expect.
Will an anti-snap upgrade help with my insurance?
Often yes — fitting cylinders that meet the recognised standards can help satisfy insurer requirements. We fit to the standard your policy calls for.
