Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re experiencing bizarre and frustrating electrical issues in your Buick Regal, LaCrosse, Chevy Cruze, or other compatible GM model, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights and security system. When it starts to fail, it can create a cascade of seemingly unrelated problems that can be a nightmare to diagnose.
The Simple, Dealer-Free Solution for Your 2011 Regal BCM
Forget about expensive dealership visits, towing fees, and the hassle of programming a new module. Our professional cloning service provides a true plug-and-play solution. Here’s how it works: you simply purchase this listing, ship your original BCM to us, and we handle the rest. Our technicians will extract the unique, vehicle-specific data from your original module—including key programming, security information, and specific options—and flash it directly onto this replacement unit. We then ship the fully programmed module back to you, ready for immediate installation. No further programming or calibration is required.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The vehicle’s security system acting erratically or preventing the car from starting.
- ✔ False warning lights appearing on the instrument cluster (e.g., “Service Theft System”).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication issues with other vehicle modules, leading to a no-start condition.
Wide-Ranging GM Compatibility
This BCM, identified by part number 13577924 and its interchanges like 13583450, 13579004, and 13580198, is compatible with a broad range of General Motors vehicles. While this listing is focused on the 2011 Regal BCM, it also fits models such as the Buick LaCrosse, Cadillac SRX, Chevy Volt, Equinox, Camaro, Cruze, and GMC Terrain. Please verify your original part number against our list to ensure perfect compatibility.
Installation and Post-Install Notes
Installation is straightforward as the module is located in an accessible area, typically the driver’s or passenger’s side kick panel or dash area. Once installed, the vehicle should start and function correctly. However, in some cases, additional minor procedures may be needed:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It’s the brain behind your car’s creature comforts and security.
How does this programming service work?
After you place your order, we will provide you with shipping instructions. You send us your original, faulty BCM. We use specialized equipment to read the vehicle-specific data from it and transfer that data to the replacement BCM. We then ship the programmed replacement back to you.
Do I need to take my car to the dealer after installing this part?
No. Because we clone the data from your original module, this replacement BCM is a true plug-and-play solution. It will be ready to work as soon as you install it, saving you the time and expense of a dealership visit.
What if my original BCM is too damaged to be read?
In most cases, even with significant internal faults, we can still retrieve the necessary data. If for some reason your module’s data is completely unrecoverable, we will contact you to discuss other options or provide a full refund.
What happens if the airbag light comes on after I install it?
This can happen occasionally. It means the BCM needs to be synchronized with the airbag module (SDM). A repair shop with a professional-grade diagnostic tool can perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
How do I know if the BCM is really my problem?
While the symptoms listed are strong indicators, a full diagnosis by a qualified technician is the best way to be certain. Common signs include multiple, unrelated electrical issues happening at once, which points to a central controller like the BCM.
