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: Perform this procedure with the DOOR OPEN. The lock should be
set for pushbutton access to retract latch.
Tools Required: DF59 Control Key & Small at 1.8" blade screwdriver.
Read the instructions through once before attempting to change
the combination.
The factory pre-set combination is 2 and 4 pressed simultaneously (and re-
leased), then press 3 (and release).
1. Remove the control lock assembly and trim plate using the DF59 Control
Key provided with the lock (see gure 1). Turn the key to the left
(counterclockwise) until control lock assembly can be removed and the
combination change sleeve is exposed (see gure 2).
2. Turn the outside thumb piece to the left (counterclockwise) to the stop
position and release. This clears the lock of previously used buttons
(see gure 3).
3. Enter the existing combination. Make sure you depress each button fully
and release.
4. Insert screwdriver into combination change sleeve slot (see gure 2).
Turn screwdriver to the right (clockwise) to the stop position. You should
feel a slight click. Turn the screwdriver to the left (counterclockwise) to
stop, and remove.
5. Rotate the thumb piece to the left (counterclockwise) to the stop
position and release. This clears the old combination (see gure 3).
6. Select a new combination, write it down. Some or all of the buttons may
be used for your new combination - pressed individually or simultane-
ously. Each button may be used only once. We do not recommend the
use of a one-button combination.
