Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling frustrating electrical gremlins in your Chevrolet, GMC, Buick, or Cadillac? Issues like flickering lights, unresponsive power windows and locks, strange dashboard warnings, or even a car that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it fails, it can cause widespread chaos. Dealerships often charge a fortune for a new module plus expensive programming fees. We offer a smarter, more affordable path back to reliability.
This listing is for a comprehensive BCM programming service. You send us your original BCM, and we transfer all its vital data—including VIN, mileage, and security information—to a fully tested replacement unit. The module you receive back is 100% plug-and-play, completely bypassing the need for dealer intervention. It’s the most efficient way to solve your electrical issues and get your car running properly again.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Chevy Cruze with a classic case of BCM failure. The symptoms were all over the place: the radio would turn on and off randomly, the turn signals worked intermittently, and the security light would stay on, preventing the car from starting. They had already replaced the battery and checked the fuses with no luck. After connecting my scan tool, I saw a dozen communication codes, with the most significant being U0140 – Lost Communication With Body Control Module. This confirmed my suspicion. Instead of a costly new BCM and hours of programming, we used our cloning service. The customer shipped us their faulty module, we cloned it, and sent back the programmed replacement. They installed it in under 30 minutes in their driveway, and the car started right up with zero issues. It’s a fix I’ve performed hundreds of times, saving drivers time, money, and a trip to the dealer.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this service is likely the solution you need:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ The vehicle’s security or anti-theft light is on, causing a no-start condition.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other ‘U’ codes.
- ✔ Turn signals or hazard lights functioning incorrectly.
- ✔ Remote keyless entry is unresponsive.
A Straightforward Guide to Installation
Installing your pre-programmed BCM is a simple process that most DIYers can handle with basic tools. For a 2011 Chevy Cruze, the BCM is typically located behind the driver’s side kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On the Cruze, remove the driver’s side kick panel near the pedals to access the module.
- Disconnect the Old Module: Carefully unplug the electrical connectors from the original BCM. They have locking tabs that need to be depressed to release.
- Swap the Modules: Remove the old BCM from its mounting bracket and install the new, programmed module in its place.
- Reconnect Everything: Securely plug the electrical connectors into the new BCM. You should hear a click as they lock in place.
- Power Up: Reconnect the negative battery terminal.
- Test All Functions: Start the car and test your windows, locks, lights, and other body functions to confirm the repair.
Important Post-Installation Notes
While our service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up. Please be aware of the following possibilities:
- 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 airbag system with the new BCM and is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by make and model. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does this BCM cloning service work?
It’s simple. After you purchase, we will provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to a fully functional replacement module. We then ship the programmed, plug-and-play BCM back to you.
Why is this better than going to the dealership?
Our service saves you significant money and time. You avoid the high cost of a brand-new module from the dealer and eliminate the separate, expensive programming fees. The part you receive is ready for installation right out of the box.
Do I absolutely have to send you my original BCM?
Yes. The data on your original module is like a fingerprint for your car, containing the VIN, security keys, and specific options. Cloning this data is the only way to guarantee a true plug-and-play solution without requiring additional programming.
What if my original BCM is water damaged or won’t communicate?
In many cases, even with significant damage, our advanced tools can still retrieve the necessary data. If we are unable to clone your module for any reason, we will contact you immediately to discuss options.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module after sending it to us for the data transfer service.
What happens if my airbag light turns on after installation?
This can occasionally happen as the vehicle’s safety systems sync. The ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional diagnostic tool to clear the light. This is a standard procedure for many module replacements.
