HELP!!!! 2002 Chevy Blazer, need to program the key fob!!!

I have a 2002 Chevy S-10 Blazer, need the programing sequence. I have tried the hold the unlock button and turn the key in the ignition a few times, I was also told (on the net) to hold unlock and just put the key in, but dont turn it. Someone please help me to figure out how to get this programed. You can either post it here, or email me at [email protected] In the subject please put something that stands out, I get a lot of spam.

Thanks,
Rich
