How to Change the Combo

The door must be open.
On models with the passage feature, make sure the passage feature is disengaged: turn knob or key should be in vertical position.

1. Insert the DF-59 control key into the
combination change plug assembly
and unscrew the cylinder by turning the
key counterclockwise. Remove the
combination change plug to gain
access to the combination change
sleeve (see figure 14-1).

2. Turn the outside lever once to the stop
position then release. The latch should
not retract (see figure 14-2).

3. Enter the existing combination. On new
installations, use the factory-set
combination: depress 2 and 4 simultaneously,
(release), then 3 (release). You
should feel a slight click as each button
is depressed.

4. Insert the spanner wrench as shown in figure 14-3 to engage the combination change sleeve. Gently turn the spanner wrench clockwise to the stop
position (a slight click should be felt), then turn the spanner wrench counterclockwise to the stop position (see figure 14-4). Remove the spanner wrench.

5. Turn the outside lever once to the stop
position then release. The latch should
not retract (see figure 14-2).

6. Choose your new combination, then enter the new combination — depress buttons carefully (a slight click should be felt as each button is depressed).  

Note: You can use one button or all five
for a combination, but each button can
only be used once. You can depress two
or more buttons simultaneously as a step
in the combination. At least 3 digits are
recommended in the code.

7. Turn the outside lever once, all the way,
until it stops, hold in position and make
sure the latch is retracted fully. (See
figure 14-5). Release the lever.

8. Turn the lever again to the stop position. At this point, the latch should not retract unless you enter the new combination (see figure 14-6).

9. Resecure the combination change plug
assembly by screwing it in clockwise
with the DF-59 key — do not overtighten
(see figure 14-7). Remove the key
and store it in a secure area with these
instructions and the spanner wrench.
