J. INSTRUCTIONS FOR RESETTING UNKNOWN
COMBINATIONS
Follow the instructions in Section I, “Disassembling the lock.” Remove the lock
from the door and disassemble it as instructed (See Figure I-1 to I-4) .
To remove the 3-sided dust cover marked "Kaba Simplex," place the
combination chamber in the position below.
J-1 Place a small screwdriver on the edge of the
3-sided dust cover and push down on the
screwdriver (See Figure 10-1) . The cover
should pop loose. Once it does, pull the
cover off of the combination chamber.
J-2 Hold the chamber in one hand by the screw
tab (b) on each end with the key-stems (c)
facing you and the control shaft (d) at the
bottom (See Figure 10-2) .
J-3 Using the sector (pie shaped cam) on the control shaft, rotate the control
shaft (d) counter-clockwise and release to clear the chamber (See Figure
10-2) .
J-4 Look at the 5 code gears (e). If any code gear
pockets (f) are already at the shear line (open
position), ignore them. They are not used in
the combination (See Figure 10-3) .
J-5 Find the code gear pocket (f) that is farthest away from the shear line
(open position). Depress the key-stem (c) and release (See Figure 10-3) . If
any digits in the combination were depressed together (at the same time),
then they must also be depressed together to reset the code.
J-6 Find the code gear pocket (f) that is the next farthest away from the
shear line (open position). Depress that key-stem (c) and release (See
Figure 10-3) . If any of the code gear pockets travel past the shear line,
the key stems have been depressed in the
wrong sequence. Start over at Step J-3.
J-7 Repeat step J-6 until all code gear pockets (f)
are at the shear line (open position).
J-8 If all the code gear pockets (f) are not lined up
at the shear line (open position), start over at step J-3.
J-9 Depress the lockout slide (g) at the top of the chamber and release. (looks
like one end of a spark plug) (See Figure 10-4).
J-10 Rotate the control shaft (d) counter-clockwise to clear the chamber and
release. The lockout slide (g) should pop out (button will not move yet)
(See Figure 10-4) .
J-11 Depress key-stem/s (c) 3 and 5 simultaneously, then 4, releasing each
after it is depressed (See Figure 10-2) .

I. DISASSEMBLING THE LOCK/
REVERSING THE LATCH
You may need to disassemble the lock to reverse the latch on spring latch
models or to clear a lost combination.
I-1 Remove the lock housing (A) from the inside of
the door by removing the three mounting
screws (See Figure 9-1) .
I-2 Remove the center plate and barrel assembly
(B) by removing two screws and flange washers
(See Figure 9-2 and 9-3) .
I-3 Remove the 2 gear plate screws (C)
(See Figure 9-4) .
Note : Skip step I-4 if reversing the latch.
I-4 Remove the combination chamber (D) by
removing one screw at each end of the
chamber (See Figure 9-5) .
Reversing the Latch
I-5 Depress the latch and hold it.
I-6 Use the tip of a screwdriver to gently lift the
gear plate by the exposed edge so you can
grasp it with your fingertips.
I-7 (See Figure 9-4) . Remove the gear plate (C)
and place it aside. Note that the activating arm
(E) is attached to the gear plate and will rise
with the gear plate.
I-8 Release the latch slowly. Pull it out, reverse it,
and reinsert it.
I-9 Depress the latch and hold it.
I-10 (See Figure 9-4) Reattach the gear plate (C).
Make sure that the stud on the end of the acti-
vating arm (E) is resting in the curved slot on
the throw cam (F).
I-11 When the gear plate is flush with the back sur-
face of the lock, release the latch and replace
the screws attaching the gear plate.
I-12 Reassemble the center plate and barrel
assembly (See Figure 9-2) .
