Is Your Cadillac or GM Vehicle Experiencing Strange Electrical Problems?
If you’re dealing with a frustrating array of electrical gremlins—from power windows that won’t cooperate and door locks with a mind of their own, to flickering interior lights or a security system that randomly activates—the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause widespread and unpredictable issues. Replacing it at a dealership can be a costly and time-consuming process, requiring expensive programming tools. We offer a simple, effective, and direct solution.
From the Diagnostic Bay
We had a 2015 Cadillac SRX come in that was a textbook case of BCM failure. The owner reported the dome lights would stay on, draining the battery overnight, and the key fob would only work intermittently. After confirming the BCM was the source of the voltage drain, we used our cloning service. The customer sent us their original module, we transferred the data to a replacement unit, and shipped it back. They installed it in their driveway in under 30 minutes. The lights worked perfectly, the key fob responded instantly, and the battery drain was gone. It’s a powerful fix that saves hundreds compared to a dealer visit.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ Malfunctioning keyless entry and security alarm systems.
- ✔ Inaccurate gauge readings or warning lights on the dashboard.
- ✔ Communication errors with other vehicle modules, leading to various system failures.
- ✔ Unexplained battery drain when the vehicle is turned off.

Post-Installation Information
In most cases, this module is a direct fit with no further steps needed. However, depending on your specific vehicle, a couple of minor recalibrations may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Core Policy: There is no core charge for this service. You can keep your original module.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security systems, and climate controls.
How does the cloning/programming service work?
You send us your original BCM. We use specialized equipment to read the unique data from it—like your vehicle’s VIN, key codes, and specific options—and write that exact data onto the replacement module we provide. This makes the new module an identical twin to your original, allowing it to work in your car without any further programming.
Is this truly a plug-and-play installation?
Yes, for over 99% of installations. Because we clone your vehicle’s original data, the replacement BCM is ready to be installed and function immediately. In rare cases, as noted above, a simple relearn procedure for the airbag or brake pedal sensor may be needed.
What happens if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still retrieve the necessary data. If for some reason your module’s data is completely corrupted and unrecoverable, we will contact you to discuss options, which may include a full refund.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary key and security information is stored within the BCM itself, which we will transfer during the cloning process.
How long does the entire process take?
Once we receive your original module, the programming process typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a tracking number as soon as your new module is on its way back to you.
