I reprogrammed mine and it did not make any difference. I find it difficult to believe that my antenna is too short. I never had these problems with the home link on my two previous Avalons. I am convinced the Chrysler HomeLink system is flawed. Having to baby it by holding the button in for 2 or more seconds, having to press the button numerous times, having to be directly in front of the garage door, having to move my seat up closer to even reach it, etc.....I might just as well get out of the car and manually open up the door (and get some exercise while I'm at it!). Good thing I kept my clicker.
