How Lock Snapping Works – and Why Modern Doors Are Targeted
Why are modern doors so often targeted for lock snapping?
It's mainly because many UPVC and composite doors in North London have vulnerable euro cylinders. These cylinders have a weak point around the center fixing-screw hole.
Intruders can easily exploit this by gripping the cylinder with a snapping tool, breaking it at the weak spot in seconds. Once snapped, they can turn the exposed cam to open the door without a key or causing noise.
This method is alarmingly quick and effective against standard cylinders that protrude from the handle.
Many new builds and retrofitted conversions in areas like Drayton Park, Holloway, and Finsbury Park were initially fitted with these basic factory cylinders, making them prime targets.
To combat this, we fit TS007 3-Star Kitemark anti-snap cylinders, which feature a sacrificial front section.
This design guarantees the core remains protected, defeating the attack.
