Understanding Lock Snapping and How to Prevent It - Locksmith Manchester

If you have a UPVC or composite door, it is highly likely secured by a Euro Cylinder lock. While these doors are structurally sound, standard Euro cylinders possess an inherent design flaw that has led to a specific type of burglary sweeping across Manchester and the wider UK: "Lock Snapping." It is fast, destructive, and requires no specialist picking skills.

What is Lock Snapping?

A standard Euro cylinder is relatively thin in the middle, right where the retaining screw holds it in place. Burglars exploit this weakness. Using standard DIY tools like mole grips or a claw hammer, they apply force to the protruding end of the cylinder. The lock simply snaps in half at its weakest point. Once the front half is removed, the burglar can reach into the mechanism and manually unlock the door. The entire process often takes less than 15 seconds and generates very little noise.

Are You Vulnerable?

Take a look at your external doors. Does the metal cylinder where you insert the key protrude more than 3mm from the handle casing? If it does, a burglar has enough purchase to grip and snap it. Furthermore, check the face of the cylinder. If it does not display the British Standard Kitemark and a 3-Star rating (usually three engraved stars), it is a standard lock and is entirely vulnerable to this attack.

How to Secure Your Home

The solution is straightforward but critical: upgrade to TS007 3-Star Anti-Snap cylinders. These high-security locks are engineered with a "sacrificial front." If a burglar attempts to snap the lock, the very front section breaks away harmlessly, but the central core remains secure and locked, preventing access to the internal mechanism. Furthermore, these cylinders are reinforced with hardened steel pins to resist drilling and picking.
