: BCM replacement

12-10-12, 10:37 AM
What will car do if u change out ur BCM for another used BCM from a same yr car? I know a new bcm needs to be programmed? But what about using a used bcm? I have an 03 vue without keyless entry. I read u can install a bcm from a car with keyless to make it work. Everything I read is about putting a NEW bcm in, not using a used bcm. Just wondering.
