This is an exhaustive book on making keys for disc tumbler locks via sight reading. It is a very useful skill when a key cannot be made by code. Impressioning is often used to make keys for locks without codes, but impressioning can be rough on locks and can be time consuming. Sight reading is where a locksmith looks into a disc tumbler lock, observes the relative heights of the wafers, and cuts a key accordingly.
The first time you look into a lock, write down the observed disc heights, cut a key accordingly by space and depth, and it works the first try—that is a mile stone. It can be fast and has no risk of damaging a lock—so easy it is almost fun. But it does require some skill and some special tools. The Foley-Belsaw course, and the old Locksmithing Institute course each had a chapter on sight reading, but they were just enough, in my opinion, to introduce the topic. There could be a steep learning curve going up against anything but the most ordinary locks.
This is where this book comes in. It goes over a lot of the potential landmines and could save someone a lot of frustration in learning the skill.
It is a useful skill in automotive locksmithing, but it can be used for non-automotive wafer locks as well. This book devotes a very large chapter, around 60 pages, to sight reading non-automotive locks, including nuances specific to certain locks that could throw you off. So it is a useful book even if you have no interest in automotive work but do need to make keys for office furniture, L and T-handle locks, or locks for tool boxes.
Sieveking has a less-expensive book for an introduction to sight reading, but for a little more, why not get the big book?
