I had 2 factory keys made at SOS. They also had the SKREEM and ECM for diagnostics at the time because of starting problems. SOS should be able to cut the key for you and then tell you the procedure to program the key to you SKREEM / ECM without removal. This will take some time if you are not in the Portland area because you would need to ship them your key. Cost was $220 for single key with remote door lock. Without the remote it is $75. For $75 it will open the door and start the car.

Dealer at the time said it takes them 2 weeks to get a key cut and cot $300+.
