I just bought key blanks from an ebay site in Nov. Two blanks, one for the ignition and doors, the other for the trunk. I had only one set of keys for my car, and wanted a second set. I have a 48 D24, but the keys are supposed to fit 43-48 Chrysler, Dodge, Desoto and Plymouth. The blanks cost $12.95 for the pair plus $2.00 shipping. I know that is kind of steep for 2 blanks, but it is cheaper than replacing the locks. My local hardware store was able to cut the keys for me. I don't know if this fellow has more blanks, but it may be worth a try. The sellers name is Robert Furtado. His email is rara2u2@msn.com.
