Lock snapping is one of the most common burglary techniques used on UPVC doors in the UK. In under 30 seconds, a burglar can snap a standard euro cylinder in half and open the door without a key. Upgrading to an anti-snap cylinder is one of the most effective security improvements you can make — here's what you need to know.
What Is Lock Snapping?
Most UPVC doors use a euro cylinder — a cylindrical barrel that the key is inserted into. Standard cylinders can be snapped by applying leverage with a pair of pliers or a snap tool. Once snapped, the inner portion of the cylinder can be turned with a screwdriver to open the door. The process can take under a minute. Thousands of homes in the UK are broken into this way every year.
How Do Anti-Snap Cylinders Work?
Anti-snap cylinders incorporate a sacrificial section that is designed to snap first — on the outside of the door — leaving the inner mechanism protected. Even if a burglar snaps the outer portion, they cannot access the mechanism needed to open the door. High-quality anti-snap cylinders also offer anti-pick, anti-drill, and anti-bump protection.
Choosing the Right Cylinder
Euro cylinders come in different lengths, measured in millimetres on each side of the cam (e.g. 35/45mm). Getting the wrong length can leave the cylinder protruding from the door, making it easier to attack. A professional fitter will measure your door and fit the correct size. Look for cylinders that meet British Standard TS007 (3-star) or have Sold Secure Diamond accreditation.
How Quickly Can It Be Done?
Replacing a euro cylinder is one of the quickest UPVC repairs available — typically completed in under 30 minutes. The Glass Guardian recommends anti-snap cylinders as standard on all UPVC and composite door repairs and upgrades across the West Midlands. It's an inexpensive upgrade that can make your home significantly more secure.
