Restore Full Functionality to Your GM Vehicle with a Programmed BCM
Are you battling bizarre electrical issues in your Cadillac SRX, Buick LaCrosse, or Chevy Equinox? Flickering lights, unresponsive power windows, a security system that won’t cooperate, or even a vehicle that refuses to start can all point to a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and hard-to-diagnose problems. Dealerships often charge a fortune for a new module plus mandatory programming fees. We offer a simpler, more affordable solution.
This listing is for a comprehensive programming service. You send us your original BCM, and we expertly transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to a fully tested replacement module. We then ship the ready-to-install BCM back to you. This cloning process makes the replacement completely plug-and-play, eliminating the need for expensive and time-consuming dealer intervention. It’s the most reliable way to get your car back to normal without the hassle.
From the Diagnostic Bay
I remember a 2012 Cadillac SRX that came into the shop with a laundry list of complaints the owner called “automotive poltergeists.” The horn would honk randomly, the dome lights would stay on, and the key fob worked intermittently. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple U-codes (communication errors) pointing to the BCM. Instead of a costly new unit, we performed this exact cloning service. The customer shipped us his module, we cloned it, and sent the replacement back. He installed it in under 30 minutes in his own driveway, and every single electrical gremlin vanished. It’s a powerful fix for a complex problem.
Common Signs of a Failing GM BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. A failing module can often set communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001.
- ✔️ Unpredictable power door lock or window operation
- ✔️ Interior or exterior lights not working correctly or staying on
- ✔️ Malfunctioning windshield wipers
- ✔️ Instrument cluster gauges behaving erratically or not working
- ✔️ Vehicle security system faults or alarm sounding randomly
- ✔️ Key fobs not being recognized, leading to a no-start condition
- ✔️ False warning lights on the dashboard (e.g., Airbag, ABS)
A Straightforward Guide to Installation
Installing your programmed BCM is a simple process. For the 2011-2012 SRX, the BCM is typically located behind the left side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the SRX, you’ll usually find the BCM to the left of the steering column, behind the lower dash panel. Access may require removing a trim panel.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and reconnect all electrical connectors firmly until they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM systems may require a ‘handshake’ after installation. Please note the following:
- 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 airbag system with the new BCM. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any procedure.

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. We then clone all of its essential data onto the replacement module and ship it back to you, ready for installation.
Is this really plug-and-play?
Yes. Because we transfer your vehicle’s original data, the replacement BCM is recognized by your car’s other systems, avoiding the need for dealer programming. In some rare cases, a simple relearn procedure may be needed as described above.
What is the turnaround time?
We typically program and ship your replacement module within 24-48 hours of receiving your original BCM. We will send you a tracking number as soon as it ships.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we will transfer during the cloning process.
Is there a core charge?
No, there is no core charge or need to return your original module after you receive the programmed replacement. You can keep your old part.
