I have a brand-new Prius IV but the Homelink will not work on my rolling code LiftMaster garage door opener. Yes I read the manual and used the "Learn" button and pressing the Homelink button two or three times does not work. One thread suggested pressing the [now] programmed Homelink button and then checking to see if the "Learn" button light is flashing-if it is, press it and the door should be programmed. I pressed the Homelink, the "Learn" button flashed, and I pressed it. Nope, no worko. I have a 2008 Camry with the exact same programming instructions and it works flawlessly. I cleared out the "Learn" memory and reprogrammed the Camry and my touchpad, but the Prius will not work. Am I missing anything? Is it a bad Homelink? The dealer wants me to leave the car all day but they said they have no way to verify repair since they don't have MY garage door and I live ten miles away. VERY frustrating Toyota!
