If it's really a BCM issue that's a toughy to find because they are set up to the individual vehicle, including the VIN and mileage in certain cases. It's a one shot deal so you can't program it a second time. The only hope you have with a used unit is to find the EXACT car with the EXACT accessory package and MAYBE it will work out.

BTW, to know for sure you need to find someone with a high end scanner who knows how to use it... and most likely that will be a dealer.

Let us know how you make out.
