I have encountered real trouble many times but I haven’t found proper information online. I did today a key for a Kia Forte 2018. It is an 80bit chip, so there is not a lot of information out there for it. But here’s the thing i did it with the Xhorse vvdi key tool max here.
I will show you how I managed to do it. First of all I used my Autel im608 to receive vehicle information and i see that it is a 4D60 80bit chip.
In the Xhorse I went to generate transponder and I couldn’t find that chip. But there is an 80bit option between ID70-ID83 (80bits)
I went here and at the bottom here you have here 4d70 Hyundai Kia (80bit) even though this one is 4D60. I try to make this transponder into this chip here with vvdi super chip xt27. It worked and it programmed.
It is successfully programmed with im608. If you will ever need kia fortes this is the key.
Hope I managed to help you guys.
