What does anti snap lock mean?

Anti snap describes a euro cylinder lock that has been designed and tested to resist lock snapping, where a burglar breaks the cylinder to open the door. The label alone proves nothing. Look for a TS007 3 star Kitemark or Sold Secure Diamond (SS312) approval.

Are anti snap locks any good?

Yes, if they carry a recognised test mark and are fitted properly. A cylinder approved to TS007 3 star or Sold Secure Diamond (SS312) has been tested against snapping, and West Yorkshire Police advise 3 stars as the minimum when upgrading. No lock stops every attack.

How do I know if I have anti snap locks?

Look at the cylinder, the part your key goes into. A BSI Kitemark with three stars, or Sold Secure Diamond (SS312) approval, means it has been tested against snapping. One star alone does not count unless the handle carries a 2 star mark, and with no mark or paperwork, treat it as standard.

What are the best anti snap locks in the UK?

The best anti snap locks are the ones tested to a recognised standard, not a particular brand. Look for a euro cylinder with a TS007 3 star Kitemark or Sold Secure Diamond (SS312) approval, the two standards police advice names, and have it fitted at the right length so it does not stick out past the handle.

What door locks do police recommend?

Police force advice names standards rather than brands. West Yorkshire Police name TS007 and Sold Secure Diamond (SS312) for euro cylinders and advise 3 stars as the minimum when upgrading.

What are the most secure door locks in the UK?

No lock is unbeatable, so the most secure locks are those tested to a recognised standard and fitted to a sound door. For euro cylinders that means TS007 3 star or Sold Secure Diamond (SS312). For wooden doors, look for BS 3621 stamped on the lock's faceplate.
