Restore Your Vehicle’s Brain without the Dealer Headache
Are you chasing electrical gremlins in your car? Flickering lights, windows with a mind of their own, or a security light that prevents your car from starting? These are classic signs of a failing Body Control Module (BCM), the central computer for your vehicle’s comfort and security features. A bad BCM can make your daily drive frustrating and unpredictable. This isn’t just a part; it’s a solution that gets your car back to normal, bypassing expensive dealership programming and long wait times.
We offer a straightforward cloning service for your 2012 Regal BCM and other compatible GM vehicles. You simply send us your original BCM, and we transfer 100% of its data—including the VIN, mileage, and all factory-installed options—to this fully tested replacement module. When you get it back, it’s a true plug-and-play installation. No need for a GM Tech2 or other costly scan tools for programming.
A Technician’s Notebook: The Intermittent No-Start Mystery
I remember a 2012 LaCrosse that came into the shop with an issue that was driving the owner crazy. It would start fine for a week, then suddenly refuse to crank, flashing the security light. The battery was new, the starter checked out, but communication codes like U0140 (Lost Communication with BCM) were stored. After checking the wiring, we pinpointed the BCM. Internal corrosion on the circuit board, a common issue, was causing intermittent connection failures. Instead of a new, unprogrammed BCM from the dealer (which would have cost over $700 with programming), we performed a data clone just like this service. The customer had their car back in a few days, fully functional and for a fraction of the cost. This is the exact fix for those hard-to-diagnose electrical nightmares.
Is Your Vehicle Showing These Symptoms?
A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Power windows, door locks, or interior lights work erratically or not at all.
- ✔ The security or anti-theft light is on, and the engine won’t start.
- ✔ Dashboard gauges behave strangely or stop working intermittently.
- ✔ The horn, wipers, or radio function incorrectly.
- ✔ You have diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, U0155, or B-series codes.
- ✔ Key fobs are not being recognized by the vehicle.
Your Straightforward BCM Installation Guide
Installing your newly programmed BCM is a simple process. While the exact location varies by model, the steps are generally the same. Always disconnect the battery before starting any electrical work.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it to prevent accidental contact.
- Locate Your BCM: The BCM is typically found inside the cabin. Common locations include behind the driver’s or passenger’s side kick panel, under the dash, or near the center console. (Refer to your specific model’s fitment notes for its location).
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same position and reconnect all the electrical connectors. Ensure they click securely into place.
- Reconnect Power: Re-attach the negative battery terminal. Your vehicle’s systems will now be controlled by the newly installed BCM.
- Post-Installation Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. In some cases, additional steps may be needed. Please see the important notes below.
Important Post-Installation Notes
Because we clone your original data, most vehicles will not require any further procedures. However, in some instances, a system sync may be necessary:
- 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 BCM with the airbag module. This is only required if the light is on.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems can be complex. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we extract the complete software and vehicle-specific data (like VIN, mileage, and options) from your original BCM and transfer it to a replacement unit. This makes the replacement module an exact digital copy of your original, ensuring a simple, plug-and-play installation without the need for dealer programming.
Do I need to do any programming after I install it?
No. Because we clone your original data, this 2012 Regal BCM arrives ready for installation. In the majority of cases, no further programming is needed. A small number of vehicles may require a simple relearn procedure for the airbag or brake pedal sensor, as detailed above.
What if my original BCM is completely dead or ‘fried’?
In many cases, even if the BCM is non-functional in the vehicle, we can still retrieve the necessary data from the memory chip. Please contact us before ordering if your module has significant water or fire damage, as data recovery may not be possible in those extreme cases.
How does the mail-in process work?
After you place your order, we will contact you with detailed instructions and a shipping address. You securely package and ship your original BCM to us. Once we receive it, we perform the cloning service and ship the programmed replacement BCM back to you, typically within 1-2 business days. We’ll provide you with tracking information for the return shipment.
Do I need to send my key fob?
No, you do not need to send your keys or key fobs. All the key data is stored within your original BCM’s data, which we will transfer to the replacement module. Your existing keys will work immediately after installation.
Is there a core charge for my old part?
No, there is no core charge. We need your original module to perform the data transfer service, but you are not required to leave it with us. However, we do not ship your original module back unless specifically requested.
