Brake booster was replaced at mechanic shop, drove around a while before heading home no issues. Next morning the security light was on, and it hasn't turned off since. Relearn process has been done more than 15x, ignition cylinder replaced, all fuses are good, new battery. I just now received a (PLJX GM self-learning Pass lock Override module from Directed) via FedEx.
Could someone please help!
If any step-by-step wiring installation with pics. Would be more than appreciated.

The kit should have come with instructions, I have not heard of such a kit, so I am not sure what you need? So, does the security light flash or is it on steady while you drive?
