Frequently Asked Questions
What does the GM BCM clone service do?
We clone your original GM body control module (BCM) to a matching donor, transferring VIN, keys, option codes, and factory configuration so the donor works plug-and-play.
Which GM vehicles are covered 2003-2015?
Most 2003-2015 Chevrolet, GMC, Buick, Cadillac, Pontiac, Saturn, and Hummer vehicles with a standard BCM. Send the part number and VIN to confirm fitment.
Will my GM keys still work after the BCM clone?
Yes. IMMO and key data are copied directly from the original BCM to the donor, so existing keys continue to start the vehicle.
Do I have to take my vehicle to the dealer after?
No dealer visit required. The cloned GM BCM installs plug-and-play with no additional programming.
How is this different from a used junkyard BCM?
A used BCM has a different VIN, keys, and options and will not work in your vehicle. Our clone transfers YOUR data to the donor so it matches your car exactly.

i had been searching for a BCM for 2004 GTO for weeks with no results part stores or dealers could not come up with anything and could not program a used one. i eve called a couple of remanufacturers & they couldn’t repair mine becaused they didn’t have the programming.
I ran across Karmamauto cloning services during an online search, contacted them to check if they could clone the BCM for the GTO they replied they should be able to, sent the original & a use one I had purchased online, they cloned it & sent it back. It worked great! So happy i ran across this company i’ll be keeping there info on had for future repairs. Thank you
