How to pair HomeLink to a rolling garage door opener.
If you bought your garage door in the last 15 years, it is most likely the rolling code type.
The manual is incorrect in how it tells you to do the pairing. You must first follow the steps of a non-rolling code type, to teach the HomeLink what the garage door opener remote is transmitting. Once you have followed that step, the button on HomeLink will have a different light blink sequence than before it was trained.
Once this step is complete, then go to the step where you hit the learn button on the opener and the button you trained on the HomeLink. Hit the HomeLink button at least 3x. This should finish the pairing.
