Restore Full Electrical Function to Your Vehicle
Are you battling frustrating and unpredictable electrical problems in your Buick LaCrosse, Chevy Volt, or Cadillac SRX? Issues like flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that won’t start are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing symptoms. Dealerships often quote exorbitant prices for a new module plus mandatory programming fees. We offer a simple, cost-effective, and reliable solution.
This product is a comprehensive programming service for a replacement BCM. You send us your original, faulty BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to a fully functional replacement unit. The module you receive back is a true plug-and-play component, eliminating the need for expensive dealership programming or complex scan tool procedures. Get your car back on the road quickly and confidently with a BCM that is ready for installation right out of the box.
Diagnosing Your 2011-2012 LaCrosse BCM Failure
A faulty Body Control Module can be difficult to diagnose because its symptoms often overlap with other component failures. However, if you’re experiencing several of the issues below simultaneously, the BCM is the most likely culprit. Our programming service is the definitive fix for these problems, restoring your vehicle’s systems to factory-perfect operation.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Instrument cluster gauges behaving erratically or going completely dead.
- ✔ The security or anti-theft system preventing the car from starting.
- ✔ Key fob not working or responding inconsistently.
- ✔ Wipers activating on their own or not working at all.
- ✔ False warnings or error messages appearing on the driver information center.
Simple, Plug-and-Play Installation Process
Our service is designed for simplicity. After you place your order, we will contact you with detailed instructions for shipping your original BCM to our facility. Once we receive it, our technicians will professionally clone all necessary data to the replacement module. We then ship the programmed module back to you, typically within 1-2 business days. Installation is as simple as disconnecting the negative battery terminal, swapping the old module with the new one, and reconnecting the battery. In most cases, no further steps are needed.
Please Note Post-Installation Procedures: On some models, additional synchronization may be required. If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control function. Always consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
How does the cloning service work?
After you purchase, we will provide you with a shipping address. You send us your original BCM. We use specialized equipment to read the unique data from your module and write it onto a replacement unit. We then ship the newly programmed, plug-and-play module back to you.
Will I need to have this BCM programmed by a dealer?
No. The entire purpose of our service is to provide you with a module that is already programmed for your specific vehicle. This completely eliminates the need for any dealership programming, saving you time and money.
Is this a simple DIY installation?
For many individuals with basic mechanical skills, yes. The BCM is typically located in the driver or passenger side kick panel or behind the dash. The process involves disconnecting the battery and swapping the modules. However, if you are not comfortable working on your vehicle’s electronics, we recommend professional installation.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data. If your module has severe water or fire damage, data recovery may not be possible. Please contact us before ordering if your module is severely damaged.
What is the turnaround time for this service?
We typically program and ship your replacement BCM within 24-48 hours of receiving your original module. Return shipping times will vary based on your location and chosen shipping method.
