Changing the Code/Combination
Note: If your lock is opening on every turn of the knob or lever, except upon entering a code, this may
be a ZERO CODE. Before attempting to remove the lock from the door, refer to the troubleshooting
procedures outlined at bottom of this document for a zero code symptom/solution.
Important: The following steps must be performed while the door is be
open.
The factory pre-set combination is 2 and 4 pressed simultaneously and re-
leased, then press 3 and release.
Read the instructions through once before attempting to change
the combination.
1. Turn the outside thumbturn to the left (counterclockwise) until it stops
then return it to the right (clockwise) slowly to the horizontal position
and release.
2. Enter the existing combination.
3. Insert a Phillips-head screwdriver into the central piece of the combina-
tion change assembly (see gure 1). Gently turn the screwdriver to the
right (clockwise) until it stops. A slight click should be felt. Do not force.
4. Remove the screwdriver from the combination change assembly.
Important: When removing the screwdriver, the central piece must return to its
initial position, if not, set it back to its original position using the screwdriver
(see Figure 1). If the central piece of the combination change assembly does not
return to its original position, the combination will be cancelled and the lock will
jam.
5. Turn the outside thumbturn to the left (counterclockwise) until it stops
and return it slowly to the right (clockwise) to the horizontal position
and release.
This clears the existing code (see gure 2).
6. Select a new combination and write it down. Some or all of the buttons
may be used for your new code, pressed individually or simultaneously.
Each button may be used only once. We do not recommend the use of a
one-button combination.
