What are euro cylinders

The stars you see against locks are awarded when a cylinder has passed certain criteria of the TS007 British standard. The lower the stars the lower the standard of protection the lock is going to offer.

Are all star-rated cylinders anti-snap?

Homeowners need to be aware that in order to protect against a lock snapping attack, they need to fit a cylinder that has been tested for snap resistance and approved to either Sold Secure Diamond level or at least have the 3-star Kitemark. Contrary to popular belief a snap cylinder, even with a 1-star Kitemark is not anti-snap, no matter what it says on the packaging.

1-star cylinders are those which have passed the criteria for the British Kitemark so should resist drilling, picking and bumping; however, they have NOT passed snapping tests.

For these cases, additional 2-star level door handles can be purchased to meet an overall TS007 3-star rating.

Cylinders awarded 3-stars have passed all TS007 tests including lock snapping tests.

A 3-star Sold Secure Diamond rating, means a cylinder/lock has been tested above and beyond the usual standards required for TS007, and has also been tested by the Master Locksmiths Association.
