@DRFVDR, well, the point was to save on some cost, not spend $12,000 for a single key! Good to know though. It does look like I can get blank keys online, but still can't program it myself.
@Joker, I genuinely thought it came with two until the car got dropped off at our in-laws place. But you are correct. I should of checked. Not the end of the world though. Lots of good info on here!
Anyone familiar with the Smartbox Auto stuff? Again, if it's more than the key from the dealer it seems excessive.
I'm not at all afraid of technology. Happy to do it myself if it's an option.
