Anti-Snap Cylinders: Why You Need a TS007 3 Star Upgrade Now

If your home is secured by a standard Euro cylinder lock—the type commonly found in uPVC and composite doors across Dorset—it is highly vulnerable to lock snapping. This silent, quick, and destructive burglary technique accounts for a significant percentage of forced entries in the UK. Upgrading to an Anti-Snap cylinder is the fastest and most effective way to secure your home.

What is Lock Snapping and Why Are Euro Cylinders at Risk?

Lock snapping involves using a simple tool to apply leverage to the lock cylinder, causing it to break at its weakest point (usually the central fixing screw). Once the cylinder is broken, the burglar can easily access the internal locking mechanism and open the door in seconds. The danger is amplified because the multi-point locking system in uPVC doors is entirely reliant on the cylinder.

The Gold Standard: TS007 3-Star or SS312 Diamond

To counter this vulnerability, security standards have evolved. When purchasing a new cylinder, you must look for one of two accreditations:

• TS007 3-Star Kitemark: This means the lock has been tested and certified to resist snapping, drilling, picking, and bumping. Police-preferred specification often recommends this standard.

• SS312 Diamond Approved: This is a separate, rigorous testing standard endorsed by the Master Locksmiths Association (MLA).

A cylinder with a 3-Star rating features multiple lines of defence, including a sacrificial front section that breaks off to protect the remaining core mechanism, preventing access.

Essential Installation Check: Flush Fitting

The best anti-snap lock is useless if incorrectly fitted. A common mistake is installing a cylinder that protrudes too far from the handle.

Mandatory Safety Check: A correctly fitted euro lock cylinder should not protrude more than 3mm from the handle. Ideally, it should be completely flush. The more exposed the cylinder, the easier it is for a burglar to snap.
