So I pulled my keys out of my pocket the other day and the remote had broken off my key ring. (damn!) I was able to buy a replacement remote from one of my vendors but it has no on board programming instructions. I tried the method for programming H2 remotes as well as some of the other GM truck methods with no success. I called the service department at my dealership and they told me that the H3 can't be programmed without hooking it up to their computer but I don't buy that. Any help would be appreciated. I can just go to the dealer and have it sorted out but I'd rather not. HoKc? Hummerguy? Any thoughts?
