Passat Remote Entry

I have a 1999 Passat Wagon that I bought used and did not come with the keyless entry remote.

I purchased a banjo remote on ebay but have had no luck programming it.

Questions:
Does anyone have programming instructions they could pass along?

How do I find the fcc# to know if this is the proper remote for my car?

I have just purchased a 98 passat wagon, I went to a site called keylessride.com .. they were able to hook me up with the newer flip key and a blank that I had cut at a local Auto locksmith, Tho I had my old non working banjo to see that it was by hella, they provided me with the instructions. Do you have two keys ?
