The combination can be easily changed using one to five of the lock’s buttons in any order in the combination. Each button can only be used once. Note: Three or more numbers that are not in order are recommended for higher security. Also, two or more buttons may be pushed together (at the same time) as part of your new combination i.e. 2 & 5 at the same time.

CAUTION: The door MUST BE open during this entire procedure. 

Rotate the outside lever/knob (d) once to stop position and release to reset the lock, the latch should not retract. 

Step 1: Press the existing combination (b) followed by the ENTER button (c) and release; do not turn the lever/knob.

Step 2: Insert the release tool through hole in number pad and gently lift up loop end of the tool to depress the code change button until you hear a click; remove tool and do not press any buttons (Step 4).

Step 3: Unscrew special torx screw from inside housing using supplied torx wrench. Enter your existing combination, and depress and release the “ENTER” button. Insert longer end of the same torx wrench through the opening until it engages with the mating part. Turn wrench counterclockwise (using minimal force) approximately 90 degrees, until it clicks. Return wrench to initial position. Remove wrench and replace torx screw. 

Step 4: **This Step Is Very Important**  Rotate lever/ knob once, and only once to clear the old combination; the latch will retract; release the lever/knob. 

Step 5: Press in your new combination followed by the ENTER button (c) and release.

Step 6: Rotate the lever/knob to verify that the latch retracts confirming the validity of the new combination (if you try the old combination now, it should not work).

IMPORTANT: The “ENTER” button must be depressed and released after entering the combination. The latch will not retract until the “ENTER” button is depressed and released.
