Restore Full Functionality to Your Vehicle’s Electronics
Is your Buick LaCrosse, Chevy Volt, or Cadillac SRX plagued by bizarre electrical problems? Flickering lights, malfunctioning power windows, a security system that acts on its own, or a dashboard lit up with false warnings 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 fails, it can make driving frustrating and unpredictable. Dealerships often propose a costly replacement followed by expensive programming. We offer a smarter, more direct solution.
This is a replacement BCM that comes with a specialized programming service. We transfer the critical data from your original, failing BCM directly onto this replacement unit. This cloning process ensures that the replacement module is a perfect match for your vehicle’s specific configuration, retaining all original keys, mileage, and settings. The result is a true plug-and-play solution that eliminates the need for a trip to the dealer for programming.
From the Diagnostic Bay
We recently had a 2011 Buick LaCrosse come in with a textbook case of BCM failure. The owner was at his wit’s end. The interior lights would stay on, the driver’s side window wouldn’t go down, and the remote keyless entry worked only intermittently. He had been quoted over $900 by the dealership for a new module and the labor to program it. By using our cloning service, we were able to provide him with a ready-to-install BCM. He simply sent us his old unit, we performed the data transfer, and shipped the replacement back the next day. He installed it himself in under an hour and all the strange electrical gremlins were gone. It’s a straightforward fix that saves hundreds of dollars and significant hassle.
Is Your Vehicle Experiencing These BCM Failure Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ Malfunctioning windshield wipers or horn.
- ✔ False warnings on the instrument cluster (e.g., “Service Theft Deterrent System”).
- ✔ Remote keyless entry (key fob) not working correctly.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Communication issues with other vehicle modules, leading to various diagnostic trouble codes (DTCs).

Installation and Post-Install Notes for your 2011-2012 LaCrosse BCM
Once you receive the module, installation is as simple as removing the old one and plugging this one in. Because we’ve already handled the programming, your vehicle will recognize it instantly. However, in some GM vehicles, a couple of minor relearn procedures may be necessary after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be needed. This is a quick procedure that can be performed with most professional diagnostic tools.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and many other electronic functions that aren’t directly related to the engine or transmission.
Is this a repair service for my original BCM?
No, this is not a repair service. You are purchasing a quality replacement BCM, and the service included is the transfer of your vehicle’s specific programming from your original module to the replacement one we send you.
Will I need to have this programmed by a dealer after I receive it?
Absolutely not. The cloning service we perform makes this module completely plug-and-play. It will arrive ready for installation with no further programming required. Some minor relearn procedures, like for the airbag or brake pedal sensor, may be necessary in certain cases.
How long does the entire process take?
Once we receive your original module, our technicians typically complete the data transfer and ship your replacement unit back out within 24-48 business hours. The total time depends on shipping speeds to and from our facility.
What if my original BCM is not communicating or is completely dead?
In many cases, we can still extract the necessary data even if the module is failing or non-communicative in the vehicle. Please contact us before ordering if your module is severely damaged by water or fire, or if a technician has confirmed it is completely unreadable.
