Restore Your Vehicle’s Electrical Stability and Functionality
Are you battling a frustrating wave of electrical gremlins in your vehicle? One moment the power windows work, the next they don’t. The key fob is unresponsive, the security light flashes for no reason, or worse, you’re facing an intermittent no-start condition. These aren’t just annoyances; they’re classic signs that your Body Control Module (BCM)—the central command center for your car’s comfort and security features—is failing. In my 20+ years of diagnostics, I’ve seen how a faulty BCM can make a perfectly good car feel unreliable. This isn’t a problem you have to live with.
We offer a straightforward, reliable solution: a professionally programmed replacement BCM. This isn’t just a part in a box; it’s a comprehensive service. You simply ship us your original BCM. We then transfer its unique data—including key programming and vehicle-specific options—to a fully tested, reliable replacement module. The result? A true plug-and-play component that restores function without requiring a costly trip to the dealership for programming. This service is designed for both seasoned mechanics and DIYers who want a definitive fix.
A Technician’s Notebook: The Ghost in the Machine
A 2012 LaCrosse came into my bay with a list of symptoms that sounded like a poltergeist had taken up residence. The radio would switch off, the dome lights would flicker while driving, and the remote start worked only half the time. The owner had already replaced the battery and checked the main grounds. After running a full network scan, I noticed intermittent communication loss codes (U0140) pointing to the BCM. Instead of just dropping in a new module and sending the customer to the dealer for a $200+ programming fee, we performed a cloning service just like this one. Once the cloned module was installed, every single electrical gremlin vanished. It’s a perfect example of how targeting the root cause with the right service saves time, money, and immense frustration.
Common Signs of a Failing GM BCM
If your vehicle’s BCM is on its way out, you’ll likely notice several of these issues. A scan tool may also reveal communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes.
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lighting (flickering, staying on, or not turning on).
- ✔ Key fobs that stop working or only work sporadically.
- ✔ The vehicle’s security system engaging randomly, preventing the car from starting.
- ✔ Inconsistent operation of the radio, climate controls, or instrument cluster gauges.
- ✔ A ‘Service Theft Deterrent System’ message on the dash.
Your Straightforward BCM Installation Guide
Our cloning service makes the physical swap simple. Once you receive your programmed module from us, follow these general steps. The BCM location varies by model (e.g., LH kick panel in a LaCrosse, RH engine compartment in a Volt), so confirm the location for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down completely.
- Locate the BCM: Access the Body Control Module. This typically involves removing a kick panel, dash panel, or console trim piece.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the exact same position. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect Power: Re-attach the negative battery terminal and tighten it securely.
- Test and Verify: Start the vehicle and test all body functions: windows, locks, lights, radio, and key fobs to confirm the repair was successful.
Important Post-Installation Notes
While our goal is a seamless plug-and-play experience, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and typically straightforward.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old module to us. There is no core charge or fee.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the vehicle-specific data and flash it onto a replacement module. We then ship the ready-to-install BCM back to you.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary immobilizer and key fob data is stored within your original BCM, and we transfer that information directly to the new unit. Your existing keys will work seamlessly.
Is this really plug-and-play? Will I need to go to the dealer?
Yes, for over 99% of installations, this is a completely plug-and-play solution that requires no additional programming or dealer visits. In rare cases, a simple relearn procedure like for the airbag or brake pedal sensor might be needed, as noted in the description.
What is the turnaround time for the programming service?
We pride ourselves on a fast turnaround. The programming is typically completed and the replacement BCM is shipped back out within 24-48 hours of us receiving your original module.
Do I have to return my old BCM? Is there a core charge?
No, there is absolutely no core charge. You can keep your original module. Our price includes the replacement BCM and the programming service.
Which part number will I receive?
You will receive a fully compatible replacement BCM that interchanges with the long list of part numbers in the description, including 13583450, 13580198, and others. It will be programmed specifically for your vehicle.
