Just remember if your car sits for 3 days without being touched, your onstar shuts down. I had this one time when we went on vacation. I figured I'd lock the keys in my truck, then just use the My Chevy app to unlock it when I got back off the ship. This way I didnt have to worry about my keys. Well, onstar could not unlock my truck. They couldnt even force a wake up to it. I had to have roadside assistance come and pop the truck open. NOT FUN WHEN WITH THE WIFE AT THE CRUISESHIP TERMINAL WAITING WITH THE TRUCK LOCKED UP. This is one thing most people dont know. They said they couldnt even locate the truck to give the location to the tow truck. WAY TO GO ONSTAR!!!!!
