2003 GMC Jimmy lug nuts

Visit a tire shop and have them see if they have one that will fit OR if not have them use one of the toothed removal sockets that can be purchased all over the place. It is a tool that looks like a socket with file teeth inside it. You drive it on with a hammer and then remove the locking nuts. If you have the type with the security sleeve you remove one of the other lug nuts, then use a welder to lock the sleeve, then use the above tool.
