Anti-Snap Cylinder Locks: Why Every Home in London Needs One

Cylinder snapping is the most common method used by burglars to bypass uPVC and aluminium door and window locks in the UK. The fix is straightforward and inexpensive — but millions of London homes still have vulnerable standard cylinders installed.

What This Guide Covers

• Cylinder snapping takes less than 60 seconds — standard euro cylinders offer almost no resistance
• Anti-snap cylinders have a sacrificial section that breaks away before the mechanism is compromised
• Look for TS007 3-star rating — the highest UK security standard for cylinder locks
• Replacement cost: £30–£80 per cylinder including fitting — one of the best security investments available
• Also check for anti-pick and anti-drill features on any replacement cylinder
