The lock must be disassembled to a point the exterior of the lock can be pulled away from the door and the information on the sticker made note of. This link will give you instructions for various models of Schlage locks: There is a video on that page.

Snap off the back cover (opposite where you punch the numbers) by pinching the sides and pulling off. Do not press a pen or anything into the small light, you do not need too. Just pinch and yank off cover. You will see a small light and beside it is a small SET button by the batteries, it is labelled. Press this Set button for 2 seconds.
The red LED will light on the front code side and beep twice to indicate you are in programming mode. Enter your current code that you want to change (factory set is 12345) and then press the button that looks like a little lock on the keypad. Enter the digits '10' and press the lock button again. Enter the new code (must be six digits) and then press the lock button again. The red light should go on continously for 10 seconds.
