The 111 cars had three (3) different keys. One for the doors, one for the trunk and one for the ignition - all different keyways. The easy way out is to obtain the ignition key code from the data card and have a locksmith cut a key to that code. Blanks are available as well as the cutting service on line. I think the last one I had done was by Rfurtado1 on eBay. It worked great and costs were very reasonable.
