My wife has a 2007 Chevy Malibu Maxx and it has a remote start on it. As stated above her check engine light came on and it disabled the remote start feature. Also last year the remote start feature had stopped working(actually the whole remote stopped working) and we took it to a GM dealership. They said that sometime in the past her keys had been dropped and it broke a small clip inside. Its probably what was referred to above. Anyways they said it couldnt be fixed so we purchased a new key remote thing for her.
