Problem:
I tried to add a key on a Ford EU Transit Connect 2013 diesel, but when I get close to the end, it says security access denied. I am using autel im608.
Solution:
You can clone this key with xhorse key tools.
Feedback:
I cloned the original key using xhorse vvdi mini key tool, then did the 8 times On and Off and managed to program the remote. It is amazing that sometimes a not expensive tool can save you when autel im608 get stuck (probably due to a bug in this particular car itself).
