LOCK CYLINDER CODING
KEY IDENTIFICATION AND USAGE
The lock cylinder keyway is designed so that
other model keys will not enter a current model lock
cylinder. Two noninterchangeable keys are used.
• Square headed key is used in the ignition lock
cylinder.
• Oval headed key is used in all other lock
cylinders.
Key identification is obtained from the four
character key code stamped on the knockout portion
of the key head and an identification letter stamped on
the key shank. After the code number has been
recorded by the owner, the plugs should be knocked
out of the key head. From these numbers, the lock
combination can be determined by use of a code list
(available to owners of key cutting equipment from
equipment suppliers). If key code numbers are not
available from records or from the knockout plug, the
lock combination (tumbler numbers and position) can
be determined by laying key on diagram in Figure 1.
CUTTING K E Y S
• Determine special code from the code list or the
key code diagram (Fig. 1).
• Cut a blank key to the proper level for each of six
tumbler positions.
• Check key operation in the lock cylinder.

REPLACEMENT LOCK CYLINDERS
Lock cylinders are available from service parts
warehouses. The new cylinder has a locking bar staked
in place. Tumblers are also available and must be
assembled into the cylinder.
ASSEMBLING AND CODING LOCK CYLINDERS
Tumblers for all locks are shaped exactly alike
with the exception of the notch position on one side.
As the key is inserted in the lock cylinder, tumblers are
lowered to the correct height so that notches on each
tumbler are at the same level. When the notches on all
six tumblers line up, the side bar is pushed into the
notches by two small springs. This allows the cylinder
to turn in its bore. Five types of tumblers are used to
make the various lock combinations. Each tumbler is
