As titled, possible to add key to an Audi Q5 2015 BCM2 encrypted using Xhorse VVDI2?
Yes, both add key and all keys lost.
vvdi2 andvvdiprog do the job like a beast
How do you do it when it is encrypted?
plug into car obd try read and make note of part no and software version, take bcm2 out put adaptor on for prog and read data1 under correct setting on prog, load data1 into vvdi2 and check info is correct, read data2 on prog and load into vvdi2, now you have immo file and service file, write service file back with prog, now put bcm2 back on car and program obd with immo file.
