Locksmithing and Electronic Security Wiring Diagrams

This book is really good.Ok.. I have no experience with locks and doors..But this book is really helping me..It has a really cool approach to teaching you..It shows you how to draw door locking circuits.And.. while your learning to draw the circuits.. the author explains the correct way to connect all the components..This is really a cool way to learn this subject..I don't claim to know much more about lock smiting. But this book is helping me get a foot in the door.. lol

Good price, friendly communication, book is exactly as described, arrived quickly.What more do I have to say?

Great resource
