1999 GMC Sierra 5.3 Keyless question

[MrCPUQC]

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!

You can replace the BCM but yes the dealer is going to have to reprogram it to enable everything. I suggest getting a 2002 BCM so that you can get the auto unlocking doors as well whenever you go into park. 

 

I cannot remember how easy or hard this is. I believe it is install, then take it to the dealer but I honestly can't remember

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...

Yes I believe that will work.
