Well, you guys with 1999+ Contours, other Fords and many Imports don't have to worry about getting your car stolen with the key. Even if they take the Vin to the dealer and have a key cut, they still need to program it into PATS. In order to do this on 1999+ versions of the TI embedded chip PATS, you must have two working keys. So, while they may be able to get a key cut, they won't be able to program it so it will start your car. That is unless you give them both of your other sets of keys as well.
TI switched to this form of key programming after getting reports of crooked dealers who would clone clients keys while their cars were in for service. By requiring both keys to program a third, it makes it virtually impossible for someone to clone your key without your knowledge.
