A small format interchangeable core pinning chart is an expanded key
bitting array (KBA) that speeds pinning. At the left is a key bitting array.
The control combination is merely a change key that has been set
aside.
The inset at the left shows the pin stack for
the first change key possibility in the first
chamber.
The “3” from the KBA is in the large oval.
To the right of the oval are the pins needed
to make the #3 cut work with the #2 cut of
the top master key and the #1 cut of the
control key. Pin stacks are read from the
bottom up.
The complete pinning chart contains every
possible pin stack for every possible
change key and master key in the system.
To pin a core to a given key, find the bitting
of the key in each position in the large oval
and install the pins indicated in the squares
next to the oval.
The bottom row beneath the heading
“complete pin stacks for constants”, gives
complete pin stacks, including top pins, for
the rotating constant method, or for pinning
to master keys only.
Factory bitting lists come with pinning
charts.
SKD’s and cross keying
SKD’s and cross keying cannot be pinned
from this chart. SKD’s are never master
keyed. Cross keying must be calculated
separately for each specification.
