Likely need to replace the body computer(SJB/GEM?) that has the master code embedded. And, that likely has to be set to the VIN by a dealer, but, perhaps, if you are lucky, FORSCAN might have the ability. Could be a new module can be set by using the 'as built' list, obtainable by VIN from a FoMoCo web site reference somewhere on this site.Y’all say the master code is etched in stone, but what if your disgruntled ex posted your master code all over Facebook, Twitter, and other social media?
Surely you could have it changed for a price (maybe a steep price),right?
