In 1982 the LIST Council's predecessor released to the industry The Professional Glossary of Terms Relating to Cylinders, Keys and Master Keying. The Associated Locksmiths of America, Inc. was the first to publish and distribute it. The definitions and terminology in the glossary have since been adopted by most manufacturers, publications and associations as our industry standard. The LIST Council was asked by ALOA and others to complete what would amount to a Dictionary for Locksmiths. Credit is to be given to the Lock Industry Standards and Training (LIST) Council, Copyright @ 2006, for the definitions used herein.
