So this is embarrassing to share but hopefully I can help someone from doing what I did.
I drove the car an hour away to do laps for charity at Texas Motor Speedway.
Got to the track, shut the car off while checking in and waiting to go to the track and low and behold when I went to start the car I got a message on the display, "No Key Fob Detected."
Somewhere between moving cars in the garage and driveway at home, I set the key fob in the garage thinking it was the key to the Malibu that I had to move to get the Camaro out. It was the Camaro key. The key fobs are identical, even had the exact same dealer key chains on them so it was an easy mistake to make.
The car drove all the way to the track and I never got a warning or anything.
I called OnStar and all they could do was offer to tow me.
Seems like a flaw in the design but I actually had three other people tell me that day while I waited for my key to be delivered (thanks dad, still saving my butt at 43 years old) that they have done the same thing.
The Camaro fobs no longer have a keychain and the Malibu fobs do to keep me straight and from ever doing this again.
I hope this helps keep someone else from making this mistake.
