how to program lock/unlock horn on a 2001 GMC Yukon XL

I need to know how to program (or re-program) the horn to blow when i lock and unlock my Yukon. Its a 2001 and when I lost my keys, I bought a replacement remote FOB. Well, the new remote does not honk the horn, so I usually get the alarm to go off whenever someone unfamiliar with this locks my Yukon and think they did;t properly lock it. This is really becoming a hassle and I'd just like to re-program it so the horn honks again.
