Restore Full Electrical Function to Your GM Vehicle
Is your 2011-2012 Buick LaCrosse, Chevy Equinox, or GMC Terrain suffering from bizarre and unpredictable electrical problems? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, managing everything from power windows and locks to interior lighting and the security system. When it begins to fail, it can create a cascade of frustrating issues that are often difficult to diagnose. This listing offers a simple, cost-effective, and permanent solution: a replacement BCM programmed specifically for your vehicle through our professional cloning service.
We recently had a 2011 GMC Terrain in the shop with a classic BCM failure symptom: the owner reported the horn would randomly go off in the middle of the night. They had already replaced the battery and checked the horn relay to no avail. After connecting our diagnostic scanner, we saw erratic signals originating from the BCM. Instead of a costly new module and programming at the dealer, we used our cloning service. We transferred the data from the faulty original to a quality replacement unit. The customer had their vehicle back the next day, problem solved, for a fraction of the dealership’s quote.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely culprit. This programmed LaCrosse Body Control Module is designed to resolve these problems directly.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior dome lights or exterior parking lights staying on, draining your battery.
- ✔ Keyless entry remote failing to lock or unlock the doors.
- ✔ Vehicle’s anti-theft or security system acting up or preventing the car from starting.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminating without a clear cause.
- ✔ Wipers, radio, or climate control functions behaving erratically.
- ✔ A distinct clicking sound coming from under the dashboard.

Installation and Post-Install Notes
Once you receive the module, installation is as simple as removing the old one and plugging in the new one. Because we’ve cloned your data, no further programming is required. However, in some specific cases, minor sync procedures may be needed:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of reading the essential, vehicle-specific data from your original BCM and writing it onto a replacement module. This includes your VIN, mileage, key fob programming, and factory-installed options. The result is a true plug-and-play part that your vehicle recognizes as its own.
Why is this better than buying a used BCM from a junkyard?
A standard used BCM will not work when installed in your vehicle because it contains the data from the donor car. It would require expensive and complex programming by a dealer or specialized locksmith. Our service eliminates that step entirely, saving you time and money.
How long does the programming service take?
We typically complete the cloning process and ship your replacement module back out within 1-2 business days of receiving your original BCM at our facility.
Do I need to send my keys or any other parts?
No, you only need to send us your original Body Control Module. All the necessary key and security information is stored within the module itself, and we will transfer it to the replacement unit.
What if my original BCM is not communicating or is severely damaged?
In most cases, even with communication issues, we can still extract the necessary data. If your module has extensive physical or water damage, please contact us before ordering so we can assess the likelihood of a successful data recovery.
How do I confirm this part fits my vehicle?
The best way to ensure compatibility is to match the part number from your original BCM to one of the numbers listed in our description. This module fits a wide variety of GM models including the LaCrosse, Volt, SRX, Terrain, Equinox, Camaro, Cruze, Orlando, and Regal within the specified years.
