Thank you for your answer! Let's say I know someone who has a Tech2 device. Would he be able to reprogram it? I know someone who has one and if I can save up going to the dealer it would help me...

Hi there! I hope you are all doing fantastic on this fine day. I recently bought a 1999 GMC Sierra 2x4 with power locks and windows, unfortunately, it dosen't seem to have the remote keyless entry. That is an option that I really want. I have saw with a bit of research that replacing the BCM could enable it. Could it be done easily plug-n-play? I do not have the AU0 option only AU3. Would the dealer be able to reprogram it to enable it? Thanks!
