Hi all, new to the forums. Need some guidance on a 2020 GMC Acadia with a bad BCM. Found numbers matching one and need to change the VIN on it. I've looked at some of the softwares on here but confused as to what I need exactly. Any help would be appreciated. Thanks

While new BCM is still outside the vehicle, try to dump the eemprom from replacement module - to find the stored PIN number. It will be easier to program this module to vehicle.

Without knowing PIN of replacement module and your car PIN - you will not proceed with programming module to this car.
