Restore Full Functionality to Your Vehicle’s Electronics
Are you battling frustrating and unpredictable electrical issues in your Buick Regal, Chevy Cruze, GMC Terrain, or Cadillac SRX? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often symptoms 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 cause a cascade of seemingly unrelated problems. This listing offers a straightforward and reliable solution: a replacement BCM, part number 13578420, that is professionally programmed with your vehicle’s original data.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Instrument cluster warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Key fob not working or responding inconsistently.
- ✔ Vehicle’s anti-theft or security system engaging randomly.
- ✔ Wipers or horn activating unexpectedly.
- ✔ No-start conditions where the engine cranks but won’t fire up due to security system confusion.
The Smart Solution: Our BCM Programming Service
Instead of purchasing a blank module from a dealership and paying hundreds for programming and calibration, our service simplifies the entire process. We perform a direct data transfer (cloning) from your original BCM to this replacement unit. This means the replacement module arrives at your door as a true plug-and-play part, already configured with your vehicle’s specific VIN, mileage, and electronic settings. This is the most efficient way to get your car back on the road without the hassle of dealer appointments.

- ✔ Send Us Your Module: Carefully package and ship your original BCM to our facility.
- ✔ We Program Your Part: Upon receipt, our technicians will expertly transfer all critical data from your original module to the replacement unit.
- ✔ Receive Your Ready-to-Install BCM: We ship the programmed replacement BCM back to you, typically within 1-2 business days. You will receive tracking information once it’s on its way.
Installation and Post-Install Considerations for Your 2011 Regal Body Control Module
Installation is straightforward: disconnect the battery, locate and remove your old BCM (typically found in the driver’s side dash or kick panel), and install the programmed replacement. While our programming service makes this a plug-and-play repair, some vehicle systems may require a recalibration after the new module is installed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly is this BCM programming service?
This is a service where we transfer the essential data—like your VIN, mileage, and security information—from your original, failing Body Control Module to this fully functional replacement unit. This makes the replacement part plug-and-play, saving you a trip to the dealership.
Why do I have to ship my original BCM to you?
Your original BCM holds the unique electronic ‘DNA’ of your vehicle. By shipping it to us, you allow our technicians to extract this data and perfectly clone it onto the replacement module, ensuring seamless integration and functionality.
Is this BCM truly ‘plug-and-play’?
Yes, for all the primary functions. The module will be pre-programmed to your vehicle’s VIN. However, as noted, certain secondary systems like the airbag (SRS) or brake pedal position sensor may require a simple relearn procedure with a scan tool after installation.
How long does the programming and shipping process take?
Once we receive your original module, our programming service is typically completed within 1-2 business days. We will then ship the programmed replacement back to you, and you will receive an email with tracking information.
What happens if I don’t perform the post-installation procedures?
If a procedure like the Airbag System Sync is required and not performed, the airbag warning light will remain on your dash. Similarly, not performing the brake pedal relearn could lead to issues with brake light operation or traction control warnings.
Do I need to return my old part after installation?
No, there is no core charge for this part. You can keep your original module after you send it to us for the initial data transfer.
