Security rating
The security rating helps you choose the lock that is most suited to your needs.
For this reason, B'Twin defined a test protocol with an independent laboratory, CNPP, based on real-life theft techniques.
This unique protocol allows each lock to be given a comparable rating from 0 to 10 indicating how theft resistant it is.
