What are anti-snap locks?

Anti-snap locks are high-security cylinders designed to withstand 'lock snapping', a common burglary technique. They have a built-in weak point that breaks off if attacked, leaving the core of the lock mechanism intact and your door still secure.

What does BS3621 mean?

BS3621 is a British Standard for thief-resistant locks. Many home insurance policies require external door locks to meet this standard. We supply and fit a wide range of BS3621-compliant locks.

Can you upgrade my existing locks to high-security versions?

Yes. In most cases, we can upgrade your existing euro cylinder, mortice, or night latch locks to modern, high-security, insurance-approved versions in a single visit.

Protect Your Property From Lock Snapping

Lock snapping is a technique that requires no skill or specialist tools, allowing burglars to bypass standard euro cylinder locks in seconds. The vast majority of homes with UPVC or composite doors in Ipswich are still fitted with these vulnerable locks.

We strongly recommend upgrading to TS007 Diamond or 3-Star rated anti-snap cylinders. These locks have a built-in 'sacrificial section' designed to break away if attacked, leaving the core of the lock mechanism intact and your door securely locked.
