BCM "Re-Learn" Procedure.
So I was thinking about getting a replacement BCM, since my mechanic was so nice to me, I decided to see if I could help him out with a Cobalt he has in his shop.
He will be replacing the BCM, his problem is the Anti-Theft system will not let him start the car, I had this issue when somebody attempted to rob my Cobalt, so since I love my Cobalt so much, when it was at the dealership I stayed with it. After they soldered all the cut wires back into place, I saw the re-learn procedure, I peeked at their instructions on their computer in the service area, it was called "Learn New Key", or something like that. They never got it done while I was there, but they were working too many cars at once, maybe they messed up a part of the procedure. The next day they got it working.
The re-learn procedure was something like power on (but do not attempt to start engine) 10 or so minutes, then turn key to off, then repeat the procedure a few more times, then power on for 30 seconds, then finally attempt engine start.
This information could be very useful for those replacing BCM and want to replace and reprogram them themselves.
Thanks for any information.
