I have tried reprogramming pats keys before with maxisys ms906bt unfortunately it didn't work the programming options are there in the scanner however they don't work, I used the ford ids and vcm and I programmed the keys no problem, when you contact autel they ask you for the log file, you provide the log file to them, they don't do anything with it, sometimes this $2000 dollar autel scanners are just paper weights, they claim to do the functions like pcm coding and it doesn't work do your self a favor and try the $200 dollar clone vcm, it worked for me.
