Are you battling frustrating and unpredictable electrical problems in your 2012 Buick Regal or other compatible GM vehicle? Issues like flickering dashboard lights, power windows and locks that have a mind of their own, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). As the central command center for your car’s comfort and convenience features, a faulty BCM can make driving a nightmare. This isn’t just an annoyance; it can impact safety systems and leave you stranded.
Forget the expensive trip to the dealership and the hassle of programming a new module from scratch. We offer a simple, reliable solution. This listing is for a replacement Body Control Module (interchangeable with part numbers 13580696, 123589093, 13588446, 13584692, and 13583542) that is professionally programmed using the data from your original unit. Simply ship your existing BCM to us, and our expert technicians will clone all the critical vehicle-specific information to this replacement. We then ship it back to you, ready for a straightforward installation. It’s the most efficient way to get your car back to 100% functionality.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system light stays on, or the car alarm goes off randomly.
- ✔ The engine won’t crank or start, even with a good battery and starter.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with other modules (U-codes).
- ✔ Horn honking unexpectedly or not working when pressed.
From the Diagnostic Bay: A Real-World Repair Story
A customer brought in a 2012 LaCrosse with a ghost in the machine. The dash lights would flicker, the radio would cut out, and occasionally, the car just wouldn’t start. They had already replaced the battery to no avail. After hooking up my scan tool, I saw a slew of communication errors pointing to the BCM. Instead of charging them for hours of diagnostic time and a brand-new module plus dealership programming fees, we recommended this cloning service. We had them send us their original 2012 Regal BCM equivalent, we cloned it, and sent the replacement back. The customer installed it in under 30 minutes, and every single electrical issue was resolved. It’s a testament to how effective this service is for saving both time and money.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: The location varies by model (e.g., under the driver’s side dash in a Regal, in the passenger kick panel in a LaCrosse). Consult a service manual for your specific vehicle to find it.
- ✔ Remove the Original BCM: Carefully disconnect all electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Ship to Us: Package your original BCM securely and ship it to us. We will contact you with shipping instructions after your purchase.
- ✔ Install the Replacement: Once you receive the programmed module back from us, simply reverse the removal steps. Mount the new BCM and plug in all the connectors until they click securely into place.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some GM vehicles may require a couple of simple recalibration procedures after the BCM is installed. These are typically only needed if a specific warning light appears:
- Airbag System Sync: If your airbag warning light is on 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: On certain models, a brake pedal position sensor relearn might be necessary for proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for you to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. This ensures it works with your existing keys and vehicle configuration without any extra programming.
Do I need to send my keys?
No, you do not need to send us your keys. Because we are cloning your original module’s data, the replacement will recognize your existing keys automatically.
How long does the process take?
We typically program and ship your replacement module within 24-48 hours of receiving your original BCM. We will send you tracking information as soon as it ships.
Is there a core charge for my old part?
No, there is no core charge. We need your original module to perform the programming service, but you are not required to leave it with us. However, most customers find it convenient to have us handle disposal.
What if the airbag light comes on after I install it?
This is uncommon but can happen. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
