Is Your Vehicle Experiencing Strange Electrical Problems?
If your Chevrolet Volt, Buick LaCrosse, or other compatible GM vehicle is suffering from erratic lights, malfunctioning power windows, or a security system that has a mind of its own, the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s electronic accessories. When it fails, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose. Don’t let a faulty BCM keep you off the road. This is your direct, cost-effective solution to restore full functionality to your vehicle’s body electronics.
The Simple Solution: A Pre-Programmed BCM
Forget expensive trips to the dealership and the hassle of programming a new module from scratch. Our unique service simplifies the entire repair process. You purchase this BCM, and we will contact you with instructions to ship your original module to our facility. Our expert technicians will then extract the critical vehicle-specific data from your old BCM and transfer it directly onto this replacement unit. We then ship the fully programmed module back to you, ready for installation. It’s a true plug-and-play solution that retains all your vehicle’s original settings and key programming, saving you significant time and money.
From the Diagnostic Bay
We had a 2012 Chevy Equinox come in with a bizarre set of symptoms. The owner said the dome lights would flicker randomly, the driver’s side power window wouldn’t work, and the car alarm would go off for no reason. He had already replaced the battery and checked all the fuses. After running diagnostics, we traced the communication errors back to the BCM. Instead of a costly new module and programming at the dealer, he used our cloning service. We transferred the data from his failing BCM to a replacement unit. He installed it himself in under an hour, and every single electrical gremlin was gone. It’s a perfect example of how a faulty 2011 Volt BCM or its equivalent in another model can cause widespread issues, and how a properly programmed replacement is the definitive fix.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working headlights, taillights, or interior lights.
- ✔ Power windows, door locks, or mirrors behaving erratically or not at all.
- ✔ The vehicle’s security system or keyless entry failing to operate correctly.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Horn honking unexpectedly or not working when needed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.
Installation and Post-Install Procedures
Once you receive your programmed module, installation is straightforward. Simply disconnect the battery, locate and remove your old BCM, and install the replacement. While this service makes the process as simple as possible, some vehicles may require minor post-installation steps. If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, some models may require a Brake Pedal Position Relearn to ensure proper brake light and traction control function. Always consult a factory service manual for your specific vehicle if you are unsure.

Frequently Asked Questions
How does this BCM programming service work?
It’s simple. After you place your order, we will provide instructions for you to ship your original BCM to us. We then clone the essential data (like VIN, mileage, and key information) to this replacement module. We ship the programmed module back to you, ready for installation.
Do I need to go to the dealer after installing this?
No. Because we transfer all the data from your original module, this part is a plug-and-play solution that does not require any additional programming from a dealer or locksmith, saving you hundreds of dollars.
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the command center for your car’s body electronics.
Will this fix a no-start issue?
In many cases, yes. A failing BCM can disrupt the vehicle’s anti-theft system (Passlock/VATS), preventing the engine from starting. If your BCM is the cause of the no-start condition, this programmed module will resolve the issue.
What if my airbag light comes on after installation?
This is uncommon, but if it happens, it means the new BCM needs to be synced with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. Any qualified repair shop can perform this quick relearn.
