Restore Your Vehicle’s Brain without the Dealer Headache
Are you chasing electrical gremlins in your GM vehicle? Flickering dash lights, power windows with a mind of their own, or a security system that prevents your car from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a host of frustrating and seemingly unrelated problems. In my 20+ years of diagnostics, I’ve seen how a faulty BCM can make a perfectly good car or truck feel unreliable. This is the simple, cost-effective solution.
This isn’t just a replacement part; it’s a complete service. We provide a quality-tested BCM that is professionally programmed using the data from your vehicle’s original module. This cloning process transfers all the critical, vehicle-specific information—like your VIN, key fob data, and factory-installed options—to the new unit. The result is a module that is ready to install right out of the box, saving you from expensive dealership programming fees and the need for specialized diagnostic tools. It’s the most direct path to getting your vehicle’s electronics working as they should.
From the Diagnostic Bay: The Impala with Phantom Electrical Issues
A customer brought in a 2016 Impala with a laundry list of bizarre complaints: the radio would randomly shut off, the dome light wouldn’t work, and occasionally the turn signals would stop flashing. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I found multiple ‘Loss of Communication’ codes with various modules. This pointed directly to a failing BCM. Instead of a costly new module and hours of programming at the dealer, we used this exact cloning service. We had their original BCM shipped to us, transferred the data, and sent the replacement back. The customer installed it in under an hour, and every single issue was resolved. It’s a prime example of how a Programmed GM BCM can be a fast and reliable fix.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security or anti-theft light is on, causing a no-start condition.
- ✔ Key fobs or remote start suddenly stop working.
- ✔ The horn honks randomly or doesn’t work.
- ✔ Multiple communication error codes (U-codes) stored in the system.
- ✔ Wipers activating on their own or not working when commanded.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- ✔ Locate the BCM: The BCM’s location varies. Common spots include under the steering column, behind the driver’s or passenger’s side kick panel, or on the firewall. Your owner’s manual or a quick search for your specific model will confirm its location.
- ✔ Remove the Old Module: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in place of the old one. Reconnect all electrical connectors firmly until they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.
- ✔ Perform Relearns (If Needed): In some cases, an airbag light or brake system message may appear. If so, follow the post-installation procedures noted below. Most vehicles will not require this step.
Important Post-Installation Information
Our cloning service makes this repair as simple as possible, but due to the complexity of modern vehicle systems, a couple of additional steps might be needed on rare occasions:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Disclaimer: We’ve made this process as straightforward as possible. However, procedures can vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you.
What if my original BCM is not communicating or is water damaged?
In many cases, even if the BCM is non-communicative or has physical damage, we can still recover the necessary data. Please contact us before ordering if your module has severe damage so we can confirm the likelihood of a successful data transfer.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary immobilizer and key fob information is stored within the BCM itself, and our cloning process transfers it over seamlessly.
Is there a core charge for this part?
No, there is absolutely no core charge. You are welcome to keep your original module after our programming service is complete.
How long does the whole process take?
We typically program and ship your replacement module the same business day we receive your original. The total turnaround time will depend on shipping times to and from our facility. We always provide tracking information for the return shipment.
