There is a couple ways to change the keypad code. If this doesn't work then email me or reply here and I'll type out the others but this should work and is the easiest. - Enter your current 4-digit code and press # - Press the new 4-digit password you have chosen, then press enter. - The opener light will flash one when the password has been learned. - Test by pressing the new password, then press enter. The door should move.
