Restore Full Functionality to Your Buick Lucerne
Are you experiencing frustrating electrical issues with your 2006-2011 Buick Lucerne? A failing Body Control Module (BCM) is often the culprit behind problems like erratic power windows and locks, malfunctioning interior lights, a faulty security system, or even a ‘no-start’ condition. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module is the definitive solution to get your vehicle operating correctly again.
From the Diagnostic Bay
We recently had a 2009 Lucerne in the shop with a classic case of BCM failure. The customer complained that their interior lights would stay on, draining the battery overnight, and the remote key fob worked only intermittently. After confirming power and grounds to the module, we identified the internal BCM circuits as the cause. Installing a VIN-programmed BCM like this one resolved all the issues in a single visit, saving the customer from the headaches of a dealership appointment and the high cost of dealer-level programming.
The Plug-and-Play Advantage: Programmed to Your VIN
Don’t waste time and money at the dealership. We take the hassle out of the replacement process. Before we ship your part, our technicians will program this Lucerne Body Control Module with the latest GM software updates, specifically matched to your car’s Vehicle Identification Number (VIN). This ensures that the module communicates perfectly with your vehicle’s other systems right out of the box, making installation as simple as possible. Just provide your VIN at checkout, and we’ll handle the rest.
Common Symptoms of a Failing BCM:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Erratic instrument cluster behavior or warning lights.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Remote keyless entry (key fob) not working correctly.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ Unexplained battery drain when the vehicle is off.
Installation and Post-Install Considerations
While this module is designed for a straightforward swap, some vehicles may require a simple relearn procedure after installation to ensure all systems are synchronized. Depending on your vehicle’s specific configuration, you may need a capable scan tool to perform a ‘Setup SDM Primary Key in BCM’ if the airbag light is on, or a ‘Brake Pedal Position Relearn’ for the traction control system. These procedures are often quick and ensure seamless integration. There is no core charge for this part, so you can keep your original module.

Frequently Asked Questions
Do I need to have this module programmed?
No. We program the module to your vehicle’s VIN before it ships. It arrives ready for installation, saving you a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the part until we receive this information.
What tools are needed for installation?
Installation typically requires basic hand tools to access the module’s location (on the right side of the dash in a Lucerne). In some cases, a diagnostic scan tool may be needed for post-installation relearn procedures.
What if my airbag light is on after I install the new BCM?
This may indicate that the new BCM needs to be synchronized with the airbag system. A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a qualified technician with a professional diagnostic tool.
