We upgraded from 06 Honda Odyssey to 08 Toyota Sienna AWD the other week. Posted pictures the other week. Since then have been trying to program our garage door opener and garage door at my SIL dads garage. Two of his garage doors had been programmed since he bought the van new. I erased his openers and was planning on programming both of our garage doors and at least one of his doors in case I would forget my keys. For the past 2 weeks have tried at least 6 times here and three times at his place no luck. Went on line home link advised me I would need to buy some add on unit for around $35-40 bucks.. Forget that I'll hang the garage door transmitter on the sun visor. I called Toyota the other day called his dealer today while in Morgantown still no help.
So this evening did a search on youtube. listened to 3 or 4 videos a, all suggested doing the same thing I had been doing and no help. Finally someone with a older van and a remote that looked like mine..
Tried holding remote close to overhead console NO GOOD
He then held remote in front of overhead console pressed remote and homelink button it flashes quickly YES Press that button to open or shut the garage door NOPE
So then he told to press the learning button on back or side of opener and then within 30 seconds press the button on home link that you had just pressed that was flashing quick. Pressed it YES garage door opened and closed... using the home link button.
The fellow said he had a Chrysler that acted the same way. He did the same thing and it worked fine for him. and certainly helped me.
