I have an '09 Yukon so the OnStar functionality is fairly limited. But, I was maintaining the service - or so I thought. The card I had on file expired and I received no notification from OnStar that the charges weren't going through. Sure enough, the keys got locked inside one day (WAY too easy to do on this vehicle!) and I figured no problem - OnStar remote unlock! I called OnStar provided the security responses and asked for a remote unlock. They said "nope. your service isn't active." We then realized that the card had expired and I offered to update the card. "You have to press the blue OnStar button to update your billing info." HOW CAN I PRESS THE BUTTON IF I'M LOCKED OUT???? Called AAA - far better money spent.
