Lock snapping is one of the most common methods burglars use to break into homes — but you can stop them in their tracks with anti-snap locks. In this article, we’ll explain what lock snapping is, why it’s a growing concern, and how upgrading your door locks can keep your family and belongings safe.

What Is Lock Snapping?
Lock snapping is when a burglar applies force to a standard euro cylinder lock, breaking it in half to access the locking mechanism. It’s quick, quiet, and unfortunately, very common in uPVC and composite doors with older locks.
How Anti-Snap Locks Keep You Safe
Anti-snap locks are specially designed to resist this attack. They have a sacrificial section that breaks away under force — but keeps the rest of the lock secure, stopping intruders from gaining entry.
For maximum protection, choose TS007 3-star rated or SS312 Diamond approved cylinders — these meet the highest security standards. BUT…. bare in mind the higher the security, higher the cost. this is where AGW Locksmiths can recommend the best products to suit your needs and budget.
