My other car has wings
When I bought my GTO about 14 months ago this extra FOB was on the key ring with the standard OEM key FOB. It has no name or buttons on it, only some FCC numbers. I popped it open and it does have a 2032 battery in it. I've had it stashed in my glove box all this time but never knew what it does, funny thing is the previous owner has no clue either! Any ideas?
