Identifying Keys


Key Numbers

This image exhibits how to identify the codes and symbols on standard Medeco keys at KU. Typically when referring to a key by codes, it is first System, then Key Symbol, and finally, if needed, Serial Number (example: This is a 30A-A11 key, or more specifically it is key 30A-A11-5).
Head of a key stamped with three codes and colored arrows labeling the bottom center code “System”, the center middle code “Key Symbol”, and the upper left code “Serial Number”)
