If I have a replacement BCM, PCM and key fob that are linked together, do I need to swap the PROM from my original PCM to the new PCM? Or is it a swap and go procedure.

Hello, I'm Danny.

Anytime you replace a module like a BCM or PCM it has to be programmed by your VIN- vehicle identification number to be sure all the equipment and options on you vehicle is programmed to the new module. After doing that it will then be plug and play. The key fob might have to be programmed to the new module. Hope this helps and thanks for using 2CarPros.
