2001 Jeep Grand Cherokee: local programmed

Customer Question

I have 2001 Jeep Grand Cherokee. A local mechanic has diagnosed the problem and determined that the vehicle needs a new BCM.

Can the existing BCM be replaced with a used BCM? If, yes ... does it need to be programmed? Or, do I have to buy a new BCM (> $500). Might there be a work around?

Also, I've read that the key is indicator of the type of BCM required. The key has a thick gray plastic casing that may contain coding.

Please help.

hi, you can replace it with a used bcm(body control module) as long as it is withing a couple of years of your vehicle.however, it needs to be the same make and model, as different models will have different accessories,electrical items etc..I would recommend going to a bone yard(salvage yard) you may be presently surprised at the pricing. no it doesn't have to be reprogrammed.

Thanks for the quick reply.

I spoke to a dealer's service and parts department, and they tell me that the unit would need to be reprogrammed because of the BCM's have VINs etched into them.

Further, they noted that if I install a used BCM it will corrupt the other modules associated with BCM. Thus, creating additional (more expensive) issues to repair.

Assuming I am good to go with a replacement BCM ... is it something a weekend mechanic can replace without too much difficulty?

I'm getting conflicting reports from dealers, online forums, etc. Sure could use some helping sorting all of this out.

yes it can be a job for a weekend mechanic, as it is really only a couple of screws mounting it in and I believe a large harness and a small harness. . all this reprogramming is a ploy to make more money.
