Thanks for your reply.
First of all, my colleague did MAKE a key with 500$ multitool wheare I couldnot make a key with over 5,000 $ AutohexII.
So it is not a matter of key.
Second, I tried option 3, then I couldnot do any thing. thus I tried option 4.
I am not sure Autohex II can do anything for BMW mini.
I was reading every single detail in Microtronik Webpage, but there was no single clue.
Any expert, please tell me something!
