[s-cars] remote keyless entry for 95.5 S6?

[Rokas Reipa]

Hey all. My 95.5 did not come with a keyless entry remote but I understand
this feature is built into my particular car. It came with a normal key(no
light) and a secondary key. I am thinking of purchasing an IR/RF fob on ebay
and programming it to work with my car. Which kind of fob do I need? I have
seen instructions on s-cars.org on how to reprogram it. Thanks,

Rokas
