Restore Your Buick’s Electrical System with a Plug-and-Play Solution
If your 2006-2011 Buick Lucerne is suffering from a cascade of baffling electrical problems—like flickering interior lights, power windows that won’t budge, a security system that acts up, or even a frustrating no-start condition—the Body Control Module (BCM) is the most likely culprit. As the central hub for your vehicle’s body electronics, a failing BCM can wreak havoc, making your car feel unreliable and unsafe. The dealership solution involves a costly new module followed by expensive programming fees. We offer a smarter, more direct path to getting your car back to normal.
This is a replacement Body Control Module that arrives at your door ready for installation. Through our professional cloning service, we transfer the essential data from your original, faulty module to this replacement unit. This process ensures that your vehicle’s VIN, mileage, and specific options are perfectly preserved. The result is a true plug-and-play component that eliminates the need for a trip to the dealer or the use of specialized scan tools for programming. Just send us your original BCM, and we’ll handle the rest, returning both your original and the ready-to-install replacement directly to you.
A Technician’s Notebook: The Confusing Case of the Lucerne
I remember a 2008 Lucerne that came into the shop with a laundry list of complaints from the owner. The radio would turn on and off by itself, the driver’s side power seat was dead, and worst of all, the car would intermittently refuse to start. The battery was new, and the alternator checked out fine. After chasing wires for an hour, we hooked up the high-end scanner and saw multiple U-codes (communication loss) pointing to the BCM. Instead of a massive bill for a new module and programming, we used a cloned BCM. The swap took less than 30 minutes, and every single electrical gremlin vanished instantly. It’s a textbook example of how a failing BCM can mimic a dozen other problems.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ The security system light stays on, or the alarm goes off randomly.
- ✔ The vehicle won’t start, but the battery and starter are good (anti-theft system engaged).
- ✔ Warning messages on the dash like “Service Theft System” or “Service Electrical System”.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
- ✔ Wipers or radio functioning incorrectly.
Your Straightforward BCM Swap Guide
- ✔ Step 1: Locate and Remove. On the 2006-2011 Buick Lucerne, the BCM is typically located on the right side of the dashboard, accessible after removing the glove box or a lower dash panel. Always disconnect the negative battery terminal before starting. Carefully unplug the electrical connectors and unbolt the module.
- ✔ Step 2: Ship Your Module. Securely package your original BCM and send it to us. Our address and instructions will be provided after your purchase.
- ✔ Step 3: We Clone Your Data. Upon receipt, our technicians will perform a full data transfer from your original module to the replacement unit, ensuring all vehicle-specific information is intact.
- ✔ Step 4: Reinstall and Reconnect. We ship both your original module and the newly programmed replacement back to you. Simply bolt the new BCM into place, reconnect the electrical harnesses, and then reconnect the negative battery terminal.
Post-Installation Checks
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure for specific systems. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure must be performed with a compatible professional scan tool. This syncs the security handshake between the airbag system and the new BCM.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be needed to ensure flawless operation of the brake lights and traction control system.
Disclaimer: Vehicle systems can vary. For detailed instructions specific to your exact model, always refer to a factory service manual or consult with a certified automotive technician.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a ‘cloning service’?
Cloning is the process of reading the critical software and vehicle-specific data (like VIN, mileage, and key codes) from your original BCM and writing it directly onto the replacement module. This makes the new module an exact digital copy of the old one, allowing it to work in your car without any additional programming.
Will I need to go to the dealer for programming after installation?
No. Because we clone your original module’s data, this part is fully programmed and ready for installation right out of the box. This service completely bypasses the need for expensive dealer programming.
Will my mileage and keys work correctly?
Yes. Our cloning service ensures that your vehicle’s odometer reading remains correct and that your existing programmed keys will be recognized by the security system, just as they were with the original module.
What is the process after I order?
After you place your order, you will receive instructions on how to ship your original BCM to us. Once we receive it, we 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.
Do you keep my old BCM?
No, we do not require a core. Your original module is always returned to you along with the programmed replacement unit.
What if the airbag light comes on after I install the BCM?
This can happen occasionally. It means the BCM and the airbag module (SDM) need to be electronically re-synced. A procedure called “Setup SDM Primary Key in BCM” will need to be performed by a mechanic with a professional-grade diagnostic tool to resolve the light.
