Resetting the Code/Combination From a Lost Code
Important: There is no procedure for nding an unknown combination from the front of the lock. A
lost combination must be cleared by removing the combination chamber from the lock housing, then
a new combination can be set.
1. Remove the back plate from the front lock housing by removing the six
back plate screws.
2. Remove the two Phillips head screws (F) securing the guide bracket (D
to the front housing. Grasp the guide bracket and slide it back to
disengage it from the clutch linkage (see gure 1).
3. Lift the two chamber links (A) o of the control shaft (B) using a small at
blade screwdriver. Mark links to assure proper reassembly (see gure 1).
4. Remove the combination chamber (E) by removing the Phillips head
screws (G) at each end of the chamber (see gure 1).
5. Remove shaft bushing (C) from control shaft (see gure 1).
6. Remove chamber cover marked ILCO UNICAN (A) (see gure 2) by gently
tapping the lip of the chamber cover (A) at the control shaft end of the
chamber (see gure 3) with a screwdriver to detach it from the staked
joints (B).
7. Lay the chamber on its side as shown in gure 4.
8. With tweezers, or other tool, slide the "E" ring (B) o the unlocking slide
stud (A) (see gure 17-4), then gently lift the end of the unlocking slide
(C) over the unlocking slide stud (A) (see gure 5).
Note: The unlocking slide (C) is under spring tension and will be easier to lift if
pushed to the left to ease tension. Swing the unlocking slide (C) suciently to
clear the gears, (D) no further than shown in gure 5.
9. Depress the lockout slide (E) as shown in gure 6. The gears (D) are now
free to rotate.
10. Turn each gear (D) so that the slots (F) are aligned as shown in gure 6.

11. Return the unlocking slide (C) over the unlocking slide studs (A) while making certain the
ve toes (G) are engaged in the ve gear pockets (F). It may be necessary to adjust each gear
(D) slightly to make proper alignment between toes and gear slots (see gures 6 & 7).
Re-secure the "E" ring on the stud (A). Your chamber will now resemble gure 7 and is ready
for reassembly with the lock housing.
REASSEMBLY
1. Re-secure the chamber cover (A) marked ILCO UNICAN. Make sure the staked joints (B)
(see gure 2) on both end plates t through both slots on the chamber cover.
2. Re-secure the shaft bushing (C) with at side facing up (see gure 8).
3. Secure the combination chamber with the two Phillips head screws (G) you removed earlier.
4. Re-secure the chamber links (A) onto the control shaft.
5. Replace the guide bracket (D) by aligning the clutch linkage in the guide bracket and secure
with the two Phillips head screws (F) previously removed.
6. Replace the back plate and secure it with the six back plate screws.
SETTING THE COMBINATION
Do not attempt to set a combination until the complete unit has been reassembled.
Perform the following steps in the order shown.
1. Turn the outside lever once to the stop position and then release.
2. Enter the new combination.
3. Turn the outside lever to the stop position, make sure the latch is fully retracted, then release
the lever.
