With PATS your kind of stuck in that you need to have the replacement key programmed with a diagnostic tool if you lose one.. If you lose both, the vehicle needs to be towed (or pay for a home visit) to the shop/dealer to have the replacement keys programmed to the PATS system.. If you have two working keys, you can program your own keys off of the vehicle.. The price of the keys is about right give or take a few bucks at the dealer or locksmith level, but, you can find them new/aftermarket for about half of that on eBay and such as long as the shipping is included, or as part of the total price.. Always check shipping cost/feedback.. Most of the higher end locksmiths can program for PATS and tend to be more flexable than the dealer and may give you a better break on the key blanks as well.. Had a relative out of my area lose the keys to his 2000 Cougar,, there wasn't any Ford 'as built' data available for the Cougar (I checked) to be able to cut replacement keys off of the vehicle 'VIN' number,, so he took it to a local locksmith.. They probed/gauged the key lockset to measure for the key cut, supplied the two PATS keys, and programmed both... 175.00....
