Restore Your Buick’s Electrical System with a Hassle-Free Solution
If you’re dealing with baffling electrical issues in your 2006-2011 Buick Lucerne—like power windows with a mind of their own, flickering interior lights, or a security system that won’t cooperate—the Body Control Module (BCM) is the most likely culprit. As the central command for your vehicle’s comfort and convenience features, a failing BCM can cause a wide range of frustrating problems. Dealerships will quote you a fortune for a new module and the required programming. We offer a smarter, more affordable path forward.
This is not just a part; it’s a complete cloning service. You send us your original BCM, and our expert technicians will transfer its unique data—including key programming and vehicle-specific options—to a fully tested replacement unit. We then ship both your original module and the ready-to-install replacement back to you. The result? A true plug-and-play solution that restores function without requiring a trip to the dealer for expensive programming. This service is the most reliable way to get your 2006-2011 Lucerne BCM working correctly again.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Lucerne that was a true electrical nightmare. The radio would turn on and off, the power locks worked intermittently, and the anti-theft light would flash, sometimes preventing the car from starting. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a flurry of ‘U’ codes, indicating communication loss with multiple modules. In my 20+ years of experience, this pattern almost always points to the BCM. Instead of a complex and costly rewiring job, we performed a cloning service on his BCM. Within an hour of receiving the cloned module, the customer had it installed, and every single issue was resolved. It’s a testament to how a targeted, professional solution can save immense time and frustration.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system alarm sounding randomly or the anti-theft light flashing on the dash.
- ✔ Remote keyless entry (fob) not working correctly.
- ✔ Communication error codes, such as U0140, U0155, or other ‘U’ codes, stored in the system.
- ✔ In some cases, a complete no-start condition where the BCM fails to recognize the key.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: In the 2006-2011 Buick Lucerne, the Body Control Module is typically located behind the right side of the dashboard, accessible after removing the glove box assembly.
- ✔ Remove the Original Module: Carefully disconnect the electrical connectors. Press the release tabs firmly and pull straight out to avoid damaging the pins. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Send It To Us: Securely package your original BCM and send it to us. Once we receive it, our technicians will perform the cloning service, typically within one business day.
- ✔ Install the Cloned BCM: When you receive your original and the newly cloned BCM, simply mount the cloned unit in the vehicle and reconnect the electrical connectors. Ensure they click securely into place.
- ✔ Final Steps: Reconnect the negative battery terminal. Start the vehicle and test all body functions (lights, locks, windows, etc.). In some cases, a post-install procedure may be needed.
Important Post-Installation Notes
Our cloning service for the 2006-2011 Lucerne BCM handles the vast majority of the setup. However, due to the complex nature of modern vehicle systems, you may encounter the following:
- Airbag Light: If the airbag (SRS) warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ relearn procedure will be required using a professional-grade scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position: Some models may require a Brake Pedal Position (BPP) sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What exactly is a BCM cloning service?
It’s a process where we transfer the vehicle-specific software and security data from your original, failing BCM to a fully functional replacement module. This makes the new module plug-and-play, avoiding the need for dealer programming.
Do I have to send you my original BCM?
Yes. The cloning process requires your original module to extract the data that is unique to your car’s VIN and options. We will return your original module along with the programmed replacement.
How do I know the BCM is my problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a professional mechanic is always best. A scan tool showing communication loss codes with the BCM (like U0140) is a very strong sign.
Is this something I can install myself?
Absolutely. If you are comfortable using basic hand tools to remove some interior dash panels (like the glove box), you can perform this installation. The process is straightforward and requires no special electronic knowledge thanks to our cloning service.
What happens if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag module. A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
