The Key Bitting Array is a tool used in locksmithing that displays all possible bittings for change keys and master keys that correspond to a specific top master key. This array provides a comprehensive overview by organizing the various bitting combinations, allowing locksmiths to understand how different keys can be produced from a given top master key. This resource is particularly valuable for locksmiths as it helps them efficiently generate and manage key systems. By providing a visual representation of all potential key cuts and their configurations, locksmiths can ensure that they are creating keys that work seamlessly with the existing master key system while also recognizing how change keys relate to the top-level master key. In contrast, while a Key Matrix and a Bitting Chart may represent key cuts and configurations, they don't specifically offer the range of combinations in the same organized manner as the Key Bitting Array. A Key Diagram, on the other hand, visually represents the physical layout of a key but doesn't focus specifically on showing all possible bittings in relation to a top master key. Thus, the Key Bitting Array is the most comprehensive and relevant option for displaying change and master key relationships.
