Ok, I have a Python 1400 Remote Start on my 2002 GMC Sierra 1500. I had to get a new battery today, and now the remote start is having problems.....when the truck remote starts it immediately stops, and the installer, says they have to reprogram the starter. Does anyone know if this can be done by me, as they want 40 bucks to do it. I have mechanical knowledge and know where they mounted the brain and bypass. Thanks for any info.
