Problem:
Try to program key for BMW X5 F15 with Xhorse VVDI Key Tool Plus. But the device says it does not support unlock FEM/BDC. Any idea?
Solution:
You need to update FEM/BDC, the key tool plus has an update function. Follow the instructions and after the update, you will be able to make the key.
The main thing is that the battery is connected to the charger.
