Just bought a used H3 that did not come with the keyless remotes. I have a remote from another GM car that I would like to program for the Hummer. Is this something I can do or is it a job for the dealer?

Needs to go to the dealer. They charge the same to program multiple remotes at the same time, so I'd get at least two before going to the dealer.

 

dont assume the one u got will work,AND dont believe anything the sellers tell you about doing it yourself,they are notorious liars.
i stumbled into a dealer who did it free,,,NOT the one i bought the h3 from,booo hisss
