- bitting code — the code needed to duplicate a key WITHOUT physically tracing it
- key gauge — how you find out an existing key's code
- code card — sort of a printed version of a key gauge?
- ways to make a key from the bitting code:
-
- key level
- CK — change key — usually only opens one lock
- MK — master key
- GMK — grand master key
- GGMK — great grand master key
- GGGMK — great great grand master key
- bitting code range
- 5 or 6 pins
- each pin can be value 1 through 6
- code
- 1 = 0.328"
- 2 = 0.305"
- 3 = 0.282"
- 4 = 0.259"
- 5 = 0.236"
- 6 = 0.213"
- 7 = 0.190"
- bitting code range
- 5 or 6 pins
- each pin can be value 0 through 9
