How do I change the combination code on the TSA007 Password Lock?

First, open the lock using the current code (default 0-0-0), then press the reset button (A) firmly with a pen or sharp object until you hear a click. While holding the button, turn the thumbwheels to your desired code, then push button (B) and release button (A). Write down your new code and store it somewhere safe. (Page 9)
