Restore Your Buick’s Functionality and Peace of Mind
Are you chasing electrical gremlins in your 2006-2011 Buick Lucerne? Flickering lights, malfunctioning power windows, a security system that acts up, or strange warning messages on the dash are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating experience. In my 20+ years as a technician, I’ve seen how a single failing module can mimic a dozen different problems, leading to expensive and unnecessary repairs. This isn’t just a part; it’s the solution to restoring the reliable performance you expect from your car.
Case Study: A Tricky Diagnosis
A customer brought in their ’08 Lucerne with a laundry list of complaints: the radio would turn off randomly, the driver’s side power lock was dead, and the battery would drain overnight. They’d already replaced the battery and the alternator with no luck. A quick scan showed multiple communication error codes (U-codes) pointing to the BCM. Instead of a costly new module from the dealer requiring programming, we used a cloned unit like this one. We transferred the data from his original BCM, installed the replacement, and every single issue was resolved instantly. It’s a prime example of how the right part, properly prepared, saves time, money, and headaches.
What is Our Cloning Service?
This isn’t just a generic, off-the-shelf part. Our unique cloning service makes this a true plug-and-play solution. Here’s how it works: After your purchase, you send us your original BCM. We then extract the specific vehicle data—your VIN, mileage, and optional feature settings—and transfer it directly onto this replacement module. This process ensures that the new BCM is a perfect digital twin of your old one, eliminating the need for expensive dealership programming or complex relearn procedures. We then ship both your original module and the ready-to-install replacement back to you.
Is Your Lucerne Showing These Signs of BCM Failure?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (headlights, dome lights).
- ✔ The security system acting up or preventing the car from starting.
- ✔ A battery that drains for no apparent reason (parasitic draw).
- ✔ Warning lights on the dashboard, such as the airbag or security light.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes like U0140 or U0155.
- ✔ Wipers or climate control functions behaving unpredictably.
Your Straightforward BCM Installation Guide
For the 2006-2011 Buick Lucerne, the BCM is located behind the glove box on the right side of the dash. While professional installation is always an option, a confident DIYer can handle this job.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Access the Module: Open the glove box. You may need to press in on the sides to release the stops, allowing it to swing down completely and reveal the area behind it.
- Locate the BCM: Identify the Body Control Module. It’s a plastic box with several large multi-pin electrical connectors attached.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed or levers that need to be swung over. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Final Steps: Re-secure the glove box and reconnect the negative battery terminal. Start the vehicle and test all functions (lights, locks, windows, etc.) to confirm the repair.
Important Post-Installation Information
While our cloning service handles the majority of the setup, some vehicle systems may require a handshake with the new BCM. Please be aware of 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure brake lights and traction control function correctly.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning process work after I order?
After you place your order, we will provide you with shipping instructions to send your original BCM to our facility. Once we receive it, our technicians will perform the cloning service and ship both your original module and the ready-to-install replacement back to you, typically within 1-2 business days.
Why is this cloning service better than buying a used BCM from a junkyard?
A used BCM from another vehicle will contain the wrong VIN and equipment data, causing it to not work correctly, if at all. It would still require expensive dealership programming. Our service clones your car’s exact data, ensuring it works seamlessly upon installation.
Do I need to send my keys with the module?
No, for this BCM cloning service, we do not need your vehicle’s keys. We only need the original Body Control Module itself.
What if an airbag light comes on after I install it?
This can occasionally happen as the sensitive airbag system (SDM) detects the new hardware. It simply needs to be re-synced using the ‘Setup SDM Primary Key in BCM’ procedure, which can be done by any professional shop with a compatible bi-directional scan tool.
Is there a core charge for this part?
No. We require your original module to perform the cloning service, but we do not keep it. Your original module is always returned to you along with the programmed replacement unit, so there is no core charge or deposit.
