Well through my infinite wisdom I have managed to lose both smartkeys for my 2013 optima. I had the car towed back to the dealer and they ordered me a new key fob. Howerever, they have been trying to program the new key and its not working, now they are telling me that they might have to replace the anti theft module to do it. They have told me on 2012 and older they could reprogram it but they have never tried on a 2013. Does this makes sense?
