Problem:
Tried to add a spare Fiat 500x blade key with Xhorse vvdi key tool plus using XT1M MQB chip. Process went completely fine until key add part. Original key of course successfully added to the car but XT1M chip says “no dealer key recognized”, even though the generation went fine, tried 3 different transponders, same error.
Did anyone have such an issue?
Solution:
Use XT57B super chip to precode Jeep MQB48.

UPDATE:
After conversion of xt57b to the MQB Renegade successfully generated dealer key and learned to the car.
That worked, it’s under Special Function -> Convert Super Chip.
