3. Turn to the Right (clockwise) and pass the "CHANGE INDEX" with the second number of the combination twice and stop exactly on the "CHANGE INDEX" the third time.

4. Turn to the Left and pass the third number of the combination once and stop exactly on the "CHANGE INDEX" the second time. STOP.

5. Insert Change key into slot on back of lock. Rotate Key Clockwise. Key should rotate 1/4 turn.

STEP TWO: dial your new combination on the "Change Index";
