What Mercedes-Benz FBS3 MB key is compatible with Launch X-PROG3?
All cgdi BE key & vvdi BE keys work 100% with xprog3 (I’ve done them both with xprog3). Only changing frequency is harder ( remove resistor). VVDI or CGDI can do it by software.
It can read and write vvdi benz but with token (green bord).
Original mb keys it can write perfectly! Very good for free online calculation, and fast.
