I tried to add the Autel universal key to the 2018 Hyundai Kona USA but failed.

I generate key with firmware J9000 (same partnumber was in original working key), after that i read the IMMO pin and tried to add the key according to the KM100 instructions, but the original key was added without errors, and the newly generated key failed.

I had a similar failure when I tried to repeat the whole process with my IM508.

I used one of the keys that came with the KM100 programmer.

Maybe I need to use another new key. If so, which one?
