been a while since I have been on the forum sold my ltz a while ago and got a killer deal on a lt1 2007 Tahoe for my wife ..... So here it is it's a lt1 truck it does not have remote start and I want to make it have it I read I need to buy Gm part "#19154444" (with out tail gate lift) from what I see it's just key fobs and I need to have the dealer re program the truck for them and that's it ........ Here is the question there like 200-250$$ could I just buy used key fobs with remote start button from a junk yard or on e bay or knock off fobs on e bay and have the dealer program them To work ???
