I inherited my son's 2015 Kia Optima. I have the 2 remote keys, but I don't have the key code. I assume the key code will make replacement keys easier if (heaven forbid) that's ever necessary. Is there a way for me to get the code? Can a Kia dealer access the code for me from the remote key? The VIN# alone obviously isn't enough, because that's visible to any/everyone.
