We highly recommend this book, to both the experienced as well as the novice lock picker. It explains the concept of locks, the tools needed and a breakdown of virtually all locks on the market today. It is easy to read and is loaded with pictures and diagrams designed with the layman in mind.
"I spent 20 minutes and read the first two chapters and was able to pick my front door in about 30 seconds the first time. I had never picked a lock before."
