This morning, the wife comes in and tells me the GM car would not start. I checked it and the battery was fine, so I figured the starter had gone bad. She ended up taking the van. I got another set of keys (a newer key( to push it out of the garage and it started right up. Has anyone had a similar problem with an older GM key (the one with the security chip on the key shank) that is perhaps beyond it's usefullness?
