This is one of the most complete and up to date books on the topic. It is based on the popular and highly rated, often over-filled, course of the same name, and updated to 2018. About 370 pages, with approximately 700 illustrations and charts and a well organized Appendix, make it a vital resource for the workbench or library. Its step by step, logical, easy to read format makes it useful for beginners, and its well organized charts make it highly useful for even the most seasoned professionals.

This is the official study guide version 3 for the ILCP Exam, as approved by the Institutional Locksmiths' Association national Board of Directors in 2013, replacing the version 2 which had been written by John Truempy in 2003.

Written by two of the Locksmithing and Security Industry's most popular instructors and most prolific authors, this book will take a person from apprentice virtually to journeyman level of knowledge. Of course, the person will still need to apply the knowledge and gain time in the trade, but this is perhaps the finest preparation for them to do so in a manner that makes them an asset rather than a burden. This book will take the reader step by step into the important aspects of the Locksmithing skill sets. For the apprentice without a Master, this book can provide the basis to make them a desirable candidate for training positions. While nothing in life can truly be guaranteed, this book is very probably the best way into the trade.

This book's focus is on several advanced master keying topics, and is not intended for those not already familiar with proper master keying techniques. The skills covered should only be used by locksmiths who are well grounded in basic and intermediate master keying techniques, and fully comfortable with the Standard Progression Formula (SPF) charts and the development of standard master key systems using them. But if you are ready for the next level, including extensive coverage of incidental master keys and system threat handling, this is the book for you.
