We have developed our own security rating system that ranks the varying levels of security offered in our range of products. This system is designed to help you choose the best lock for your needs. It’s a 10 point system with 1 being deterrent security and 10 being ultimate security. If you live in a rural area and just need a lock for quick-stops then a lock with a security rating of 1 might be all you need. But, if you live in a major metro area where theft is more common, you should be considering a Kryptonite lock with a 9-10 security rating.
