Restore Your Vehicle’s Functionality with a Hassle-Free BCM Solution
Are you dealing with baffling electrical issues in your 2011 Buick Regal or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or random warning messages on your dash are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, when the BCM falters, it can create a cascade of frustrating and unpredictable problems. Many owners and even shops dread this repair, anticipating a costly new module followed by complex and expensive dealership programming. We offer a far simpler, more effective solution.
This is a listing for a replacement BCM, part number 13583450, that comes with our expert programming service. Instead of shipping you a blank module that your car won’t recognize, we transfer the critical data from your original BCM directly onto this replacement unit. This cloning process makes the replacement a true plug-and-play part, preserving your vehicle’s original mileage, VIN, and key information. You avoid the dealership, skip the programming fees, and get your car back to normal faster.
A Technician’s Notebook: The Case of the Erratic Equinox
I once had a 2011 Chevy Equinox in my bay that was driving its owner crazy. The horn would honk randomly, the interior lights would stay on, and the power locks worked only intermittently. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to a network issue. Experience told me this wasn’t a wiring problem; these were hallmark symptoms of an internally failing BCM. The module was sending corrupt data across the network, causing other modules to react erratically. By providing a cloned 2011 Regal BCM (which shares the same architecture), we had the vehicle fixed in a day, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Is Your GM Vehicle Exhibiting These BCM Failure Signs?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors not working or operating on their own.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The anti-theft or security system light is on, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights (like ABS or Airbag) appearing with no apparent cause.
- ✔ Communication error codes, such as U0100, U0140, or other U-series DTCs.
Your Straightforward BCM Installation Guide
Our service makes the physical swap simple. Here’s the process from start to finish:
- Step 1: Purchase the Service. After you place your order, we will contact you with shipping instructions. Please ensure your contact information is accurate.
- Step 2: Remove Your Original BCM. For the 2011 Regal, the BCM is typically located behind the driver’s side of the dash. Always disconnect the negative battery terminal before starting work.
- Step 3: Ship Us Your Module. Carefully package your original BCM and send it to the address we provide.
- Step 4: We Clone and Return. Once we receive your module, we will clone all necessary data to the replacement unit and ship it back to you, usually within one business day. We will provide you with return tracking information.
- Step 5: Install the Cloned BCM. Simply plug the new module in, reconnect your battery, and start the vehicle. Your original keys will work without any additional programming.
- Step 6: Perform Post-Install Checks. In some cases, a ‘Brake Pedal Position Relearn’ or ‘Airbag System Sync’ may be needed if related warning lights appear. This can be done with a bi-directional scan tool. See our disclaimer for details.

Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require recalibration after the BCM is replaced.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional diagnostic tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light operation and to prevent issues with the traction control/Stabilitrak system.
Disclaimer: Procedures can vary. We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
How does the cloning service work?
You send us your original BCM. We use specialized equipment to read the unique vehicle data (VIN, key codes, mileage, security settings) and write it onto the replacement module. This makes the new module an exact electronic copy of your old one.
Do I need to program the BCM or my keys after I get it back?
No. Because we clone your original data, the vehicle will recognize the module as its own. Your existing keys will work, and no further programming is required, making installation simple.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before purchasing to discuss options.
How long does the entire process take?
We typically clone and ship your replacement module within 24-48 hours of receiving your original. The total time depends on shipping speeds to and from our facility.
Why did my airbag light come on after installation?
This is a normal security feature. The new BCM needs to be electronically ‘introduced’ to the airbag control module (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a pro-level scan tool to sync the components and turn off the light.
Is there a core charge or do I get my old part back?
There is no core charge for this service. We will return your original, non-functional module along with the newly programmed replacement unless you request otherwise.
