yep its so common you can do the same with the xf keys..
its like one key fits all nearly..
thats why changing the locks etc is number 1 on my list of things to do to my car..
cars are a lethal weapon,your not invinsible when you get into one,and no matter how much skill you think you have,you are never in control you are always on the edge of death it may not happen today but if you keep driving like you do,you too will end up dead!
The way I was told it, Ford used some company to make the keys up to EA 30th, they only had machines that could cut something like 10,000 combinations.
Holden and Toyota did something similar, used the same company as each other up until the late 80's/early 90's. One of my mate's could get into his mate's Corolla with his Gemmi keys. Couldn't start it though.
