Is your Chevrolet Impala or other GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that randomly goes off, or a key fob that has stopped working are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated electrical issues. Don’t let a faulty module sideline your vehicle. This direct-fit replacement BCM is the reliable solution to restore order and get all your accessories working correctly again.
This isn’t just a part in a box; it’s a complete, plug-and-play solution. We take the guesswork and expensive dealership trips out of the equation. Upon purchase, simply provide us with your vehicle’s VIN, and our technicians will program the module with the latest GM software specific to your car’s configuration. This ensures that when the part arrives, it’s ready for installation without the need for an expensive scan tool or a visit to a specialist. It’s the most efficient way to solve your BCM problems and get back on the road with confidence.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a complaint of a dead battery every morning. The owner had already replaced the battery and the alternator, but the parasitic draw persisted. After hooking up our diagnostic tools, we noticed the BCM was intermittently waking up and activating various circuits, including the interior lights and radio, even when the car was off. It was a classic case of an internally shorted BCM. By installing a VIN-programmed module just like this one, we were able to solve the phantom power drain and save the customer from further diagnostic headaches. A faulty BCM can manifest in very strange ways, and this part is often the key to the fix.
Common Symptoms of a Failing 2006-2013 Impala BCM
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ The key fob has stopped working, or the remote start fails.
- ✔ The anti-theft or security system light is on, or the alarm sounds for no reason.
- ✔ Interior dome lights or dashboard lights flicker, stay on, or won’t turn on.
- ✔ Horn honks unexpectedly or doesn’t work when pressed.
- ✔ Warning messages like “Service Theft System” or other errors appear on the dash.
- ✔ Issues with windshield wiper or turn signal operation.
Installation and Post-Install Notes
Physically installing the BCM is straightforward for those with basic mechanical skills; it is typically located under the dashboard on the driver’s side. The true benefit of our service is that the complex programming is handled for you. However, depending on your specific vehicle, a couple of simple relearn procedures may be necessary after installation.
- Airbag System Sync: If you see an airbag warning light after installation, a “Setup SDM Primary Key in BCM” procedure is needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, the security system, key fob entry, wipers, and various other comfort and convenience features.
Do I need to get this BCM programmed by a dealer?
No. That’s the primary benefit of our service. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process plug-and-play, saving you time and the high cost of dealership programming.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What happens if I install this without providing a VIN?
The module will not function correctly. It contains software and settings specific to the options your vehicle was built with. Without the correct VIN programming, critical systems may not work, and the vehicle may not even start.
Is this a guaranteed fix for my electrical problems?
While this BCM resolves the most common electrical issues listed, proper vehicle diagnosis is always recommended. Problems like faulty wiring or bad sensors can mimic BCM failure. However, if you’re experiencing multiple symptoms from the list, a failing BCM is the most likely culprit.
What is the core return policy?
There is no core charge for this part. You can keep your original module without needing to send it back to us.
