Are you battling frustrating electrical issues in your 2013 Buick Regal? Flickering lights, unresponsive power windows, or random warning chimes 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 malfunctions, it can create a cascade of confusing problems. Dealerships often quote high prices for a new module plus mandatory programming fees, turning a necessary repair into a major expense. Our programming service is the smart, cost-effective solution.
We provide a fully programmed replacement BCM that is a direct-fit for your vehicle. The process is simple: after your purchase, you’ll ship your original BCM to us. Our expert technicians will then transfer all the critical data—including key programming and vehicle-specific options—to a replacement unit. We then ship the ready-to-install module back to you. This cloning service makes the replacement a true plug-and-play job, eliminating the need for expensive dealer tools or additional programming. You get your car back to perfect working order without the dealership hassle.
From the Diagnostic Bay
I remember a 2013 Regal that came into the shop with a laundry list of bizarre symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the anti-theft light would flash randomly. The customer had already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I found multiple ‘U’ codes, indicating a loss of communication with several modules. All signs pointed to the BCM. Instead of a costly new module from the dealer, we used a cloned unit. The install took less than an hour, and every single electrical gremlin was gone. The customer saved hundreds and got a reliable fix.
Common Signs of a Failing BCM
- ✔️ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔️ Interior or exterior lights staying on, flickering, or not turning on.
- ✔️ The security or anti-theft system preventing the car from starting.
- ✔️ Inaccurate gauge readings on the instrument cluster.
- ✔️ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0140, U0155, or other ‘U’ codes.
- ✔️ Horn honking unexpectedly or not working.
Your Straightforward Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: In the 2013 Regal, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel or kick panel.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. These connectors have locking tabs that must be depressed to be removed. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat the replacement BCM into the mounting bracket and secure it. Reconnect all electrical connectors firmly until they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions (lights, locks, windows, etc.). If any post-install procedures are needed (see below), perform them now.
Important Post-Installation Steps for your 2013 Regal BCM
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a final handshake between modules. Be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control function correctly, a brake pedal position sensor relearn might be necessary. This is also done with a diagnostic tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified mechanic for procedures specific to your vehicle.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. We extract the vehicle-specific data from your module and flash it onto the replacement unit. We then ship the fully programmed, ready-to-install BCM back to you.
Is this truly plug-and-play?
Yes, in over 95% of cases. Because we transfer your vehicle’s original data, the replacement BCM is recognized by the car, eliminating the need for dealer programming. In rare cases, a simple relearn procedure like an airbag sync may be required post-installation.
Do I need to send my keys?
No. All the necessary immobilizer and key data is stored within your original BCM. By cloning this information, your existing keys will work seamlessly with the new module.
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. Please contact us with your specific issues before ordering if you suspect your module is non-communicative.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after the service is complete.
