Tired of Unpredictable Electrical Problems in Your GM Vehicle?
As a technician with over two decades of hands-on diagnostic experience, I understand the frustration that comes with a failing Body Control Module (BCM). One moment your power windows work, the next they don’t. The dashboard lights up with random warnings, or worse, the car won’t start due to a security system fault. This isn’t just an inconvenience; it’s a breakdown in your vehicle’s central nervous system. This service provides a reliable, pre-programmed 2011 Regal Body Control Module, designed to restore full functionality and peace of mind without a trip to the dealership for expensive programming.
Case Study: A Tricky Diagnosis
I remember a 2013 Chevy Cruze that came into the shop with a list of bizarre symptoms. The owner reported the dome light would flicker randomly, the radio would shut off, and the “Service Theft Deterrent System” message kept appearing. A basic scan showed a slew of communication errors (U-codes) pointing to a network issue. After checking the main power and ground connections to the BCM, we found they were solid. The issue was internal to the module itself—a common failure point. Instead of a costly new BCM and hours of programming, a cloned module like this one had the customer back on the road the same afternoon with all issues resolved. It’s the most efficient and dependable fix for these specific failures.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, and interior lighting.
- ✔ The security or anti-theft system light is on, preventing the car from starting.
- ✔ Instrument cluster gauges behaving abnormally or not working at all.
- ✔ Communication error codes, such as U0140, U0155, or other U-series faults.
- ✔ Headlights, taillights, or turn signals functioning intermittently.
- ✔ The key fob is not being recognized by the vehicle.
How Our Simple Mail-In Programming Service Works
This isn’t just a part; it’s a complete solution. To ensure a 100% plug-and-play installation, we clone the essential data from your original BCM onto this replacement unit. The process is simple: after you place your order, we will contact you with clear instructions to ship your original BCM to our facility. Once we receive it, our experts will perform a full data transfer. We then ship your new, ready-to-install module back to you with tracking information. This method preserves your vehicle’s specific key codes, mileage, and option settings, eliminating the need for any additional programming.
Your Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most of these models, the BCM is located on the driver’s side, either behind the lower dash panel or in the left-hand kick panel area.
- ✔ Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Re-attach the negative battery terminal. Your vehicle is now ready to start with its functions fully restored.
Important Post-Installation Checks
In some cases, your vehicle may require a couple of simple recalibration procedures after the BCM is installed. These are standard for many modern vehicles.
- Airbag System Sync: If the airbag warning light is illuminated 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: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be necessary. This can also be done with a compatible diagnostic tool.
Disclaimer: Procedures can vary slightly by make and model. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
Do I need to send my original BCM to you?
Yes. This is a cloning service. We need your original module to transfer its unique data to the replacement unit, which makes the new part plug-and-play and avoids any need for dealership programming.
Is there a core charge?
No, there is absolutely no core charge. You can keep your original module after we have completed the programming service.
Will this fix my no-start problem?
If your no-start issue is caused by the anti-theft or security system being triggered by a faulty BCM, then yes, this will resolve the problem. Our cloning process transfers your original key data, allowing the car to start correctly.
What is the turnaround time for the programming service?
We typically program and ship the replacement module within 24-48 hours of receiving your original BCM. We will send you tracking information as soon as it ships.
What tools do I need for the installation?
Basic hand tools are usually all that’s required for the physical swap, such as a socket set and a panel removal tool. In some cases, a professional scan tool may be needed for post-installation procedures like the airbag system sync.
