What Is a 3-Star Euro Cylinder Lock?
A 3-Star security lock is the highest security rating available in the UK for euro cylinders. These locks are designed to stop the most common burglary methods, especially lock snapping, which is used in over 25% of break-ins.
In the UK, euro cylinder locks are widely used in uPVC, composite, and wooden doors, making them a common target for burglars. According to security reports, many standard euro cylinders can be broken in less than 10 seconds using simple tools if they do not have proper anti-snap protection. This is why higher security standards were introduced to improve door safety.
3-Star locks protect against:
- Lock snapping
- Lock picking
- Lock drilling
- Bumping & manipulation
They are Secured by Design approved and meet TS007 3-Star standards.
