For those of you using Xhorse universal smart keys. Here’s a nice discovery.
I got called for all keys lost on a 2014 kia optima this morning. It uses the key in the right but I don’t have it in stock. So I decided to generate the older smart key to give it a try and it’s compatible with the car. The fccid is different on each of them. I know the older style is compatible with a lot of models.
Password read smooth and key programmed on the first try. Hope this helps.
