The key is easy. You can get one cut just about anywhere, just make sure that the blank includes the Passkey chip. You can teach it to the car yourself using your existing key .
The fob is not quite as easy since it requires a separate programmer. Dormant sells one that is good for several reprogramming sessions or you can get it done by a dealer or anyone with a Tech2 or equivalent scanner.
Many of us have them, so you may be near someone who would do it for you.
