So far since them everything is fine. Went shopping with Kerri the other night and she ask" Will we get home?" I said, "I don't know". It was really windy and cold. About 28 F. But we went and survived. Who knows for sure.
GM cars have a back up way of fob recognition. You should have a slot to put the fob in in case of emergency. Check your owners manual. The chances of one fob interfering with another is extremely remote. (pun intended).
