Are you battling frustrating electrical gremlins in your Chevrolet Malibu or other GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a car that refuses to start can often be traced back to a single, critical component: the Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a failing BCM can cause a cascade of confusing problems. Dealerships often charge a fortune for a new module and the required programming. We offer a smarter, more affordable solution.
This is a comprehensive mail-in programming service for your BCM. You simply send us your vehicle’s original module, and we transfer all its vital data—including the VIN, mileage, and security information—to a fully tested replacement unit. We then ship the ready-to-install module back to you. This cloning process makes the installation truly plug-and-play, eliminating the need for expensive scan tools or a trip to the dealer. It’s the most reliable way to restore your vehicle’s electronic functions precisely as the factory intended.
Key Symptoms of a Failing BCM
- ✔ Intermittent or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working erratically or not at all.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ The radio or infotainment system behaving strangely.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication failures, such as U0140, U0155, or other U-series codes.
From the Diagnostic Bay
I recently had a 2015 Malibu in my shop with the most bizarre symptoms. The owner said the horn would honk randomly when he used the turn signal, and the dome light would stay on for hours after he locked the car. He’d already replaced the battery and checked all the fuses. A quick scan showed a dozen communication codes pointing everywhere and nowhere. This is a classic sign of a BCM failure. Instead of a new, blank module that would require hours of programming, we used this cloning service. Once the programmed BCM arrived, the swap took 15 minutes. Every single electrical gremlin was gone. It’s a textbook case of how this service saves time, money, and diagnostic headaches.
Your Simple Mail-In and Installation Process
- ✔ Step 1: Purchase the Service. After you place your order, we will contact you with detailed instructions and the shipping address. Please ensure your contact information is accurate.
- ✔ Step 2: Ship Us Your Original BCM. Carefully remove your vehicle’s original BCM and package it securely. Ship it to the address we provide.
- ✔ Step 3: We Handle the Programming. Upon receiving your module, our technicians will professionally clone all the data to the replacement BCM. This process typically takes 1-2 business days.
- ✔ Step 4: Receive Your Ready-to-Install Module. We ship your new, plug-and-play BCM back to you. A tracking number will be provided so you know exactly when it will arrive.
- ✔ Step 5: Install and Verify. Install the BCM, reconnect your battery, and start your vehicle. In most cases, no further steps are needed.
Important Post-Installation Notes
While our programming makes this a plug-and-play solution, some GM vehicles may require a simple relearn procedure for specific systems to sync correctly with the new BCM. These are not signs of a faulty part but are standard vehicle security and safety handshakes.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and turn off the light.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation or post-installation process.

Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior/exterior lighting, the security system, and communication between other onboard computers.
Why does my original BCM need to be cloned?
Your original BCM contains unique data for your car’s specific VIN and options. Cloning this data to the replacement module makes it truly plug-and-play, avoiding the complex and costly programming required by a new, blank module from a dealership.
Is this a difficult part to install myself?
For most DIYers with basic tools, the physical swap is straightforward. The BCM is typically located in the driver’s or passenger’s side kick panel or dash area. The main benefit of our service is that the electronic part—the programming—is already done for you.
How long does the entire process take?
Once we receive your original module, the programming service itself takes 1-2 business days. The total time will depend on shipping transit times to and from our facility.
What if the airbag light comes on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ can be performed by a shop with a capable scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You are free to keep your original, non-working module after the service is complete.
