Restore Full Electrical Function to Your Vehicle
Are you battling a storm of electrical gremlins in your 2011-2012 Buick LaCrosse, Chevy Volt, or Cadillac SRX? From flickering lights and unresponsive power windows to a frustrating no-start condition, a failing Body Control Module (BCM) can turn your driving experience into a nightmare. The BCM acts as the central command center for your vehicle’s body electronics, managing a vast network of features you use every day. When it malfunctions, the symptoms can be widespread and confusing. This listing offers a reliable, plug-and-play solution: a replacement BCM programmed specifically for your vehicle using the data from your original module.
From the Diagnostic Bay
We recently had a 2011 Chevy Equinox in the shop with a classic parasitic battery drain. The owner had already replaced the battery twice and the alternator once, with no success. Every morning, the battery was dead. After a thorough diagnostic, we traced the current draw to a faulty BCM. It was failing to signal other modules to enter ‘sleep mode’ after the car was shut off, causing a slow but steady drain. Instead of a costly new module and programming at the dealer, we provided a cloned unit. The installation was simple, the parasitic draw was eliminated, and the customer was back on the road without the morning dread of a dead battery.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ The security system acting up, causing alarm issues or preventing the engine from starting.
- ✔ Dashboard warning lights appearing for no reason (e.g., ‘Service Theft System’).
- ✔ Intermittent no-start or no-crank conditions where all other components seem fine.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
The Simple, No-Hassle Solution for Your 2011-2012 LaCrosse BCM
Dealerships will often quote you a high price for a new BCM, followed by several hours of labor for installation and programming. Our professional cloning service bypasses this entire ordeal. By sending us your original BCM, you allow us to perform a precise data transfer. We extract the vehicle’s unique VIN, key immobilizer information, and specific option configurations and flash them directly onto this replacement module. The result is a unit that is 100% ready for installation upon arrival. It’s a true plug-and-play fix that restores your vehicle’s factory functions without any additional programming fees or trips to the mechanic.
Installation and Post-Install Procedures
For the Buick LaCrosse, the BCM is typically located behind the driver’s side (LH) kick panel. While installation is a straightforward unbolt-and-replace process, some GM vehicles may require simple relearn procedures after the new module is connected. These do not require a trip to the dealer but may necessitate a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure correct operation of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of transferring all the vehicle-specific data—like the VIN, immobilizer key codes, and feature settings—from your original BCM to the replacement unit. This makes the replacement module plug-and-play, avoiding the need for expensive dealership programming.
Why do I have to ship my original BCM to you?
Your original BCM holds the unique digital fingerprint of your car. We need it to extract the data required to program the replacement module. Without this data, the new BCM would not be able to communicate with your vehicle’s other computers.
How long does the programming service take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. We will provide you with tracking information as soon as it ships back to you.
Is this a guaranteed fix for my car’s electrical problems?
This BCM will fix any issues directly caused by a faulty Body Control Module. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
What happens if the airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
