OK I KNOW this is a dumb question, but I have to ask. I went to rotate the tires and came to realize I do not have the lug nut key.
All that work putting it up on jacks only to see those damned locks!! Where can I get one? Or how can I get it off?

 

Have you searched your whole car?? I found mine in a weird place, don't remember where though.

Try a GM dealer.
