Pinning Formula
Technical Manual
Instructions (Fixed Core and LFIC
Chambers 1,2, 5 & 6)
Bottom Pin = shallowest operating cut
Master Pin (if required) = Deepest minus
shallowest operating cut
(Plug Total = Bottom Pin + Master Pin)
Top Pin = 10 MINUS Plug Total
Note: “0” depth of cut only available for AP key
systems. Not used with AS or AHS.

Lost Ball/Wafer Construction Cylinder
1. In the construction lost wafer chamber use #5 cut for TMK and #6 cut for CMK
2. CMK cuts for the rest of the chambers are same as TMK cuts
3. “Donut” wafer is added in construction lost wafer chamber above bottom pin
