What are Sold Secure Locks

The Sold Secure organisation test bike locks by physically trying to break them under laboratory conditions. They then rate the locks Bronze, Silver or Gold according to how long they take to break into. Gold being the best. Insurers will insist on a standard of lock to provide cover.

Who are Sold Secure?

Sold Secure is an independent organisation. It was originally setup by Northumberland and Essex police forces with the help of the Home Office. The Master Locksmiths Association took over but still work closely with police forces.

Sold Secure have their own laboratory near Daventry where they test out locks. They have a team of professional locksmiths. They test each lock using the same tools and techniques. To see which ones stand up against attacks for the longest. Sold Secure work with police on understanding new lock breaking techniques used on the streets.
