Does anyone know if the three button key fob's will work with the S4 -the ones with the trunk button
 

They are alot cheaper on ebay than the two button ones

No idea. I have three VW fobs from my 1.8T. Not sure if they can be used with an Audi?
 

Is you want one it's yours....

Thanks. That is why i love aw. I will prob just end up getting the two button. Want to keep that...
 

stock look ;-)

No problem. Good luck.

i bet they would work, just the trunk/hatch button would be useless.

I have one. They work. Center button doesn't unlock trunk, though.

Ditto, what he said, exactly the same etc ( I have one so I should know )
