Mopar Super Store or Ebay will be your friend to find an uncut and unprogrammed key. The listing below is an awesome deal. You get the key with remote and the valet key for $100 plus shipping. The seller is a good guy I've used him before--super fast shipping.
Check your Local dealership also, I think they sell the Key for about $150 and they'll probably cut it for free. If you know anyone who works for Chrysler you can get a 25% discount. If you don't just give me a holler and I'll let you use my discount .
