Resetting the Code/Combination From a Lost Code
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 figure 1).
3. Lift the two chamber links (A) off of the control shaft (B) using a small flat
blade screwdriver. Mark links to assure proper reassembly (see figure 1).
4. Remove the combination chamber (E) by removing the Phillips head
screws (G) at each end of the chamber (see figure 1).
5. Remove shaft bushing (C) from control shaft (see figure 1).
6. Remove chamber cover marked ILCO UNICAN (A) (see figure 2) by gently
tapping the lip of the chamber cover (A) at the control shaft end of the
chamber (see figure 3) with a screwdriver to detach it from the staked
joints (B).
7. Lay the chamber on its side as shown in figure 4.
8. With tweezers, or other tool, slide the "E" ring (B) off the unlocking slide
stud (A) (see figure 17-4), then gently lift the end of the unlocking slide
(C) over the unlocking slide stud (A) (see figure 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) sufficiently to
clear the gears, (D) no further than shown in figure 5.
9. Depress the lockout slide (E) as shown in figure 6. The gears (D) are now
free to rotate.
10. Turn each gear (D) so that the slots (F) are aligned as shown in figure 6.
