Did you lose the FOB, or did it become defective? If so can't you just take the key from the old one? You get 2 with the car. How hard can it be to get it duplicated?
We sure have come a long way from being able to walk into most any hardware store, and get a key cut for most any vehicle for around a buck 50.The key part is not cheap because the dealership charges a lot to cut it too.
