Hello, I was looking on Pj Grady's web site and notcied that he sold repro keys. Vin 10140 has a dual key system but according to his web site all cars after vin 4188 have a single key setup. I know there is always a chance that my ignition key could have been once replaced, but i don't believe that this was the case. Also, i went to to vin chronology and noticed that my car's vin # isn't even listed there. Maybe my car is just a fluke. - Shain #10140
