Got a used 2008 F250 SD, ignition cylinder seems rough and sticky is the best I can describe it. After truck starts I sometimes have to manually back it off a little to get out of start position. Key also hangs up and I have to wiggle it sometimes to get key out. I thought it was equipped with a chip key but a standard key that was cut at hardware store will start it. Is it supposed to be chipped, was it bypassed somehow ? Should I buy a uncoded cylinder or coded cylinder with new keys?
