For some reason if I use the gold Cadillac keys witht he crest and wreath emblem I bought on ebay to turn my ignition back to ACC (Meaning just the radio works) it won't work. The key just won't turn backwards any farther than the lock position. However if I use the GM keys pictured below it works. Anyone venture a guess as to why? It's odd, and I'm curious.
