Tired of Chasing Electrical Gremlins in Your GM Vehicle?
If you’re dealing with flickering lights, power windows with a mind of their own, or a car that refuses to start, you’re likely facing a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. Dealerships will quote you a fortune for a new module and the mandatory programming. We offer a smarter, more affordable solution.
This listing is for a replacement BCM that comes with our professional cloning service. Instead of dealing with complex programming tools, you simply ship us your original BCM. Our expert technicians will transfer all the vital information—including VIN, key data, and specific settings—to this replacement unit. We then ship the fully programmed module back to you, ready for a straightforward installation. It’s the most reliable way to get your car back to normal without the dealership hassle.
Is Your Vehicle Plagued by These Electrical Gremlins?
- ✔ Unresponsive or erratic power windows, door locks, and interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication error codes (like U-codes) when scanned with a diagnostic tool.
- ✔ Wipers or radio functioning intermittently.
From the Diagnostic Bay: The Case of the Confused Camaro
A customer brought in a 2014 Camaro with a truly baffling issue. The radio would randomly shut off, the driver’s side window would sometimes refuse to go down, and occasionally, the car wouldn’t recognize the key fob. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication loss codes with various modules. In my 20+ years of experience, this pattern almost always points to the BCM. Instead of a costly new module and hours of programming, we performed our cloning service. We transferred the data from his failing BCM to our replacement unit. The result? A 30-minute install back at his garage, and every single electrical gremlin was gone. He saved hundreds and avoided a week-long wait at the dealer.
How Our BCM Cloning Service Works
Our process is designed to be simple and effective, getting you back on the road quickly. After you complete your purchase, we will contact you with detailed instructions and a shipping address. You’ll send your original BCM to us. Once it arrives at our facility, we perform a full data transfer to the replacement module. This ensures all your vehicle’s original configurations are perfectly mirrored. We then ship the ready-to-install Programmed GM BCM back to you, typically within one business day, and provide you with tracking information. There’s no core charge, so you can keep your original module.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: The location varies by model (see fitment list below). It’s typically found under the dash on the driver’s or passenger’s side, or in a kick panel.
- ✔ Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount the replacement BCM in the same location and securely reconnect all the electrical connectors you just removed.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair. Refer to the post-installation notes below if needed.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a quick recalibration after the BCM is replaced. This is a normal part of the process.
- Airbag System Sync: If you see an airbag warning light after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the systems and clear the light.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a “cloning” service?
Cloning is the process of reading all the essential software and vehicle-specific data (like the VIN and key immobilizer information) from your original BCM and writing it onto the replacement module. This makes the new part an exact electronic copy of the old one, eliminating the need for dealership programming.
Do I need any special tools for installation?
No special programming tools are required. Basic hand tools to access and remove the module (like a socket set and screwdrivers) are all you’ll need. The programming is handled by us before we ship the part to you.
How long does the whole process take?
Once we receive your original BCM, our cloning and processing time is typically just one business day. The total time will depend on the shipping speed you choose to send your module to us and for us to return the replacement to you.
Will I need to get new keys made?
No. Because we clone your original BCM’s data, the replacement module will recognize your existing keys. This is a major benefit that saves you time and money.
What happens if my original BCM is completely dead or not communicating?
In many cases, even if a BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before purchasing to discuss options. We can often find a solution.
