Is Your GM Vehicle Experiencing Strange Electrical Issues?
If your Sierra, Silverado, Tahoe, or other compatible GM vehicle is plagued by frustrating electrical problems like flickering lights, malfunctioning power windows, erratic dashboard warnings, or a battery that dies overnight, the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from interior lighting and security systems to power locks and climate control. When it starts to fail, it can create a cascade of confusing and unpredictable symptoms.
The Dealership-Free Solution: A Pre-Programmed GM Body Control Module
Replacing a BCM traditionally means a costly trip to the dealership for the part, installation, and hours of expensive programming. We offer a simpler, more affordable solution. This listing is for a replacement GM Body Control Module that arrives at your doorstep fully programmed and ready for installation. We achieve this through a professional data cloning service. You simply send us your original BCM, and we meticulously transfer all its critical data—including your vehicle’s VIN, key fob information, and specific options—to a quality replacement unit. The result is a true plug-and-play module that restores your vehicle’s functionality without any need for additional programming.
We had a 2015 Sierra 2500 in the shop with a classic ‘mystery drain’ on the battery. The owner had already replaced the battery and alternator, but the truck would still be dead after sitting for a day. After hooking up a multimeter, we traced the parasitic draw to the BCM circuit. The module wasn’t properly putting all the vehicle’s systems to ‘sleep’ when the ignition was off. Instead of a complex and expensive new module from the dealer, we used our cloning service. We transferred the data to a replacement unit, installed it, and the parasitic draw was gone. It’s a common failure mode, and this service saved the customer hundreds of dollars and a lot of headaches.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, locks, or mirrors.
- ✔ Dashboard lights flickering or staying on without reason.
- ✔ The security system acting erratically or preventing the car from starting.
- ✔ Interior or exterior lights not turning on or off correctly.
- ✔ Unexplained battery drain that kills the battery overnight.
- ✔ Horn honking randomly or not working at all.
- ✔ Communication errors with other vehicle modules (DTC codes).

Post-Installation Notes
While our goal is a 100% plug-and-play experience, some GM vehicles may require a simple relearn procedure after installation. These can often be performed with a high-quality diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of reading the essential vehicle-specific data from your original, failing BCM and writing it onto a replacement module. This includes the VIN, security information for your keys, and settings for your vehicle’s options. This makes the replacement unit a plug-and-play part, avoiding the need for dealership programming.
Will my existing keys and remote fobs work after installation?
Yes! Because we transfer the security data from your original module, the replacement BCM will recognize your existing keys and remotes immediately. No key reprogramming is required.
Do I need to send my original BCM to you?
Yes, this service requires you to ship your original BCM to us. We cannot program the replacement module without the data from your original part. We will provide detailed shipping instructions after you place your order.
What happens if I have an airbag light after installing the new BCM?
In some cases, the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. It’s a quick procedure for any qualified shop.
How long does the entire process take?
Once we receive your original module, our cloning and processing time is typically 1-2 business days. The total time will depend on shipping transit times to and from our facility.
