Last summer, the windshield on my truck was shattered at a kids baseball game. My remote start hasn't worked since. The transmitter is still mounted in the position it was originally located, but the light isn't on. (Not sure if that is good or bad). The light on the remote still works, so I'm guessing it's not a simple battery fix. Is there some kind of reprogramming that needs to be done since the transmitter had to be removed and remounted? Is it something I can do, or will I have to take it to a tech and spend more money?
