2000 Ford Contour Transponder Key in Tucson, AZ?

Question by Italian Cop:

Does anyone who live in Tucson or Marana, Arizona know where I can get a replacement transponder key for my car. The dealership would do it, but I will need to tow the vehicle which costs more money. The Jim Click Ford says it will cost $110 for one replacement key. But the cheapest locksmith that will do it is $185. Anyone know who will re-key for a cheaper price. Thanks alot!
