Program Key fob for 2000 Yukon XL

I bought a key fob on ebay for my 2000 Yukon xl and they forgot to send me the instructions and wont reply to my emails!!! I would VERY greatly appreciate it if some one could tell me how to program the key fob. I hope that is enough information!

Give this a try http://programyourremote.com that'll get it programmed but you will still have to set the user controls, ie; seat position, radio presets, mirrors, etc.
