After pressing the "Set" button, hold down the "M1" or "M2" button for AT LEAST ONE SECOND, or until the green light comes on. You may have to hold the "Set" button for a couple of seconds as well to activate it.Then, you can also program your keyfob to link to your new settings. You do this by simply pressing the unlock button on the keyfob within 5 seconds of hitting the "M1" or "M2" buttons. Essentially, this means pressing the keyfob unlock button before the green light goes off.
