Figure out the type of garage door opener your house has. To do this, walk into your garage and look for the learn or train button on the garage door opener. If the opener has this button, you’re working with a roller code garage door opener—this type will require some additional steps when programming your HomeLinkⓇ system. If you can’t find either a learn or train button, then you have a non-roller code opener. Once you go through the main programming process, you’ll be done!
