KEY CODES
A J 4 1 0 4 9
Fig. 2J-68 Key Coding Diagram
(1) Place key over coding diagram with uncut side
of key aligned exactly with diagram. Each of five posi-
tions will align with key notches.
(2) Starting at head of key blade, determine and
record lowest level tumbler number that is visible in
each position (1 through 5).
(3) After tumbler number sequence is determined,
lock cylinder is ready for assembly.
(4) Starting at key end of lock cylinder, insert tum-
blers in proper slots and in order required by key code.
Pull side bar outward slightly to allow tumblers to drop
completely into place.
(5) Install a spring on each tumbler.
(6) Insert tumbler retainer so two end prongs slide
into slots in cylinder.
(7) Press retainer downward until it is seated.
(8) Insert key in lock cylinder and check tumbler
operation. If tumblers are properly installed, side bar
will drop downward when key is inserted. If side bar
does not move, disassemble cylinder and check for in-
correct assembly or coding of key and tumblers.
(9) If cylinder is correctly assembled and operates
properly, stake each end of spring retainer in place using
punch (fig. 2J-69).
