Restore Full Electronic Functionality to Your Vehicle
Is your Buick LaCrosse, Chevy Volt, or GMC Terrain suffering from bizarre and unpredictable electrical issues? Flickering lights, malfunctioning power windows, a security system that acts on its own, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating problems. This listing offers a straightforward, reliable solution: a replacement BCM, part number 13577924, that arrives at your door fully programmed and ready for installation.
The Simple, Plug-and-Play Solution for Your 2011-2012 LaCrosse BCM
Forget expensive dealership visits and the hassle of finding a shop with the right tools to program a new module. Our professional cloning service makes this repair easier than ever. Simply send us your original BCM, and we will transfer all the critical vehicle-specific data—including the VIN, mileage, and key information—to this quality replacement unit. When you receive it back, it’s a true plug-and-play installation. This process ensures seamless integration with your vehicle’s existing systems, saving you significant time, money, and diagnostic headaches.
From the Diagnostic Bay
We had a 2012 Buick LaCrosse come into the shop with a list of symptoms that sounded like the car was haunted. The owner reported that the interior dome lights would stay on, the radio would randomly shut off, and sometimes the car wouldn’t recognize the key fob. They had already replaced the battery to no avail. After running a full diagnostic scan, we saw multiple communication errors pointing towards the BCM. Instead of a costly new module and programming from the dealer, we used our cloning service. We transferred the data from his faulty module to a replacement unit. After a quick 15-minute install, every single electrical gremlin was gone. The customer was thrilled to have their car back to normal without a massive bill.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The vehicle’s security system or alarm malfunctions or engages randomly.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Problems with the key fob or push-to-start system.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Complete no-start condition where the engine will not crank.

Post-Installation Procedures
While our goal is a 100% plug-and-play experience, some vehicle systems may require a simple sync procedure after the new BCM is installed. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control system performance.
Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
