Restore Your Vehicle’s Functionality and Eliminate Electrical Headaches
Is your 2011 Buick Regal or other GM vehicle acting possessed? Flickering lights, a dead instrument cluster, power windows with a mind of their own, or a security light that prevents the car from starting are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your car’s electronics, when the BCM falters, it can cause a cascade of frustrating and seemingly unrelated problems. I’ve spent two decades under the hood, and I can tell you that a faulty BCM is one of the most common sources of these baffling electrical issues. It’s not just an annoyance; it can leave you stranded.
This isn’t just a part; it’s a complete solution. We offer a reliable replacement BCM (Part No. 13583450, compatible with 13586856 and others) that is professionally programmed with your vehicle’s specific data. You simply send us your original BCM, and our expert technicians will clone all the essential information—including VIN, mileage, and key data—onto this replacement unit. We then ship it back to you, ready for a true plug-and-play installation. This process eliminates the need for expensive dealership programming and special scan tools, saving you hundreds of dollars and significant downtime.
A customer brought in a 2011 Regal with a laundry list of complaints: the radio would cut out, the interior lights would pulse, and sometimes the car just wouldn’t start, showing only the security light. They had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a flurry of communication error codes (U-codes) pointing to the BCM. Instead of just selling them a new module and a hefty programming bill, we offered our cloning service. By transferring the data from their failing original BCM to a solid replacement, we had them back on the road the next day for a fraction of the dealership’s quote. It’s a reliable fix that solves the root problem without the hassle.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or total failure of power windows, door locks, or interior lighting.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Instrument panel gauges behaving erratically or not working at all.
- ✔ Horn honking unexpectedly or wipers activating on their own.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
- ✔ Inconsistent operation of the heating and A/C blower motor.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2011 Buick Regal, the BCM is typically found in the left-hand (driver’s side) dash area. For other models, its location can vary (e.g., LH kick panel, under the console). Refer to a service manual for your specific vehicle if you’re unsure.
- ✔ Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed to be released. Do not force them.
- ✔ Unbolt the Module: Remove the bolts or nuts securing the BCM to its mounting bracket and take the old module out of the vehicle.
- ✔ Install the New BCM: Mount your newly programmed BCM in place and secure it with the original hardware.
- ✔ Reconnect Everything: Plug all electrical connectors firmly back into the new module until they click into place. Reconnect the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. Note the post-installation procedures below, as some relearns may be necessary.
Important Post-Installation Notes
While our programming service for your 2011 Regal BCM makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new module. Depending on your specific model, you may need a professional scan tool to perform the following:
- Airbag System Sync: If the airbag light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration might be necessary.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician for guidance specific to your make and model.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Our technicians will then extract the necessary data and transfer it to the replacement module. We ship the programmed module back to you, ready for installation.
Do I need to get this programmed by a dealer?
No. The main benefit of our service is that the module arrives at your door fully programmed for your vehicle. This allows you to bypass expensive dealer programming fees.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and more. It’s the central hub for passenger comfort and convenience electronics.
Is this a guaranteed fix for my 2011 Regal BCM issues?
If your vehicle’s symptoms and diagnostic codes point to a faulty BCM, this service provides a reliable and tested solution. It restores the function of the module by using your car’s original programming on a quality replacement part.
Do I need to send my keys with the module?
No, you do not need to send your keys. We clone the key data from your original BCM, so your existing keys will work seamlessly with the new module upon installation.
Is there a core charge?
No, there is no core charge for this service. You can keep your original, non-functional module.
