Problem:
Every time I need to insert the Benz BE key Autel IM608 tells me invalid key. I tried 3 different Xhorse VVDI BE keys (yellow board). Even changed xp400 pro same situation.
Error “The current key is detected to be invalid.”
Solution:
Some BE Key yellow board old version 3.2 come not properly soldered.
BUT the manufacturer is aware of the flaws. There is a new version V4.2 that fixes the issues.
Green and yellow new boards work perfectly normally, something else is the issue.
It seems that it’s your USB cable. Some users had a similar situation.
Change usb cable of the programmer. Use the original USB cable of the xp400 pro, it is enough.
Feedback:
The usb cable was bad, after changing cable, it works fine.
