Sounds like the installed controller has a short somewhere.
Is there more than one fob? since it is happening in the driveway, maybe it's the other fob that has the stuck button. I know it's a long shot, but, worth trying

Bingo! Other fob was in a small wooden box on a wall unit shelf near the door we use to leave the house. Cheryl cleaned that day and stuffed a bunch of receipts and small items in the box, and to keep the lid of the box down, placed a candle in a jar on top. There must have been pressure in the right place depressing the button on the fob.
Thank you for your help. Save us $100 as we were gonna tow it to the dealer. My insurance would only tow it to the nearest yadda, yadda. Then, at the dealer, it would have worked just fine, until we got back home. Silly thing like that, but it'll be the first thing I check next time I have something related to a remote control.
