here's what you do if you have a rolling code:

1. hold down the button on your car's homelink until it flashes (25 sec?)
2. press the button on your remote
3. press the programming button on the garage opener (the actual unit hanging from your garage ceiling)
4. press the homelink button programmed to your garage door.
