FG Falcon Key programming...???

Heya all
I have a 2011 FG Ford Falcon that the owner wants a spare key.
Are they like the Euro Fords where I can just add a key or do I need to erase & pragram keys like the older AU Fords ??

Just dont want to erase keays only to find that my new key wont work

Cheers

if you have a programmed key you can add another one
