Description:This book is also available as part of my larger work, "The Dollar A Minute Locksmith - Part-Time and Full-Time Income Servicing House Locks." I offer this as a separate book for those who want to spend less. However, if you buy this book, and then other, you will end up buying it twice. This book is also a great companion to my DVD locksmith course. You can see it at www.a-bestlocksmith.com. Keying a lock is not very difficult - But your friends and neighbors are going to pay somebody to do it. It might as well be you! David Calvin has been a locksmith for over 25 years and offers a simple way to make a few hundred dollars per month keying locks for people within your social circle. This is the book for the "brass tacks" involved with the actual procedures and less of the business side. Of course, any person learning how to key locks will need to get a few basic tools and some practice locks; but having a key machine is not necessary! As always, David can be contacted for any questions on or off the job! This book covers cylinder break-down, pinning, key concepts, Kwikset Smart Key and Schlage Secure Key information, tools, etc. David recommends practicing but also adds that much of lock keying is easy to learn!
