Keyless Entry??????????????

I'm new, so cut me some slack on obviously a repeated subject.... I bought a repo 03 Ram1500. I got the build codes from a chryler dealer, the truck did come with a factory keyless system. I've bought a couple of remotes, just don't know the programming procedure. I've pulled a couple of procedes from a site, but someone may have a way specific for this truck. Thanks, Quixtr
