Restore Your Buick’s Electrical System with a VIN-Programmed BCM
Are you tired of chasing electrical gremlins in your 2006-2011 Buick Lucerne? When your power windows, door locks, interior lights, or security system start acting erratically, the root cause is often a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of constant frustration. It’s the central hub for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can affect safety systems and even prevent your car from starting.
We offer a dependable and straightforward solution. This Body Control Module, compatible with part number 10382479, is the definitive fix for these issues. The best part? We handle the most complicated step for you. Before we ship the module, we will program it with the latest GM software specifically for your vehicle using the VIN you provide. This means you can skip the expensive trip to the dealership for programming. You get a part that’s ready for installation right out of the box, restoring your car’s functionality and your peace of mind.
A Technician’s Notebook: The Case of the Haunted Lucerne
A customer brought in their 2009 Buick Lucerne with a list of bizarre symptoms: the dome lights would flicker while driving, the radio would randomly shut off, and the security light would stay on, sometimes causing a no-start condition. They had already replaced the battery and checked the fuses with no luck. After connecting my scan tool, I saw multiple communication loss codes with various modules. This immediately pointed me to the BCM. In my shop, I’ve learned that these network-wide communication faults are a classic sign of an internally failing 2006-2011 Lucerne BCM. We installed one of our pre-programmed modules, and within an hour, every single electrical issue was resolved. The customer drove away with a car that behaved like new again.
Is Your Buick Showing These Symptoms?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on/off).
- ✔ The security system acting up, causing alarm or no-start problems.
- ✔ Warning lights on the dashboard with no apparent cause (e.g., airbag light).
- ✔ Communication errors with other vehicle modules when checked with a scan tool.
- ✔ Inconsistent operation of the heating and A/C blower motor.
Your Straightforward BCM Installation Guide
Installing your new 2006-2011 Lucerne BCM is a manageable job for a confident DIYer. Follow these steps carefully for a successful replacement.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the 2006-2011 Lucerne, the BCM is typically located on the right side of the dash, often accessible by removing the glove box or a lower dash panel.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Critical Final Steps: After installation, certain procedures are required. Use a capable diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ routine to ensure the airbag system communicates correctly and extinguish the warning light. Some models may also need a Brake Pedal Position Sensor recalibration.

Frequently Asked Questions about the 2006-2011 Lucerne BCM
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your car’s specific options require. This ensures all features work correctly and makes the installation a plug-and-play process, avoiding a costly trip to the dealer.
Is this a difficult part to replace myself?
For someone with moderate mechanical skill, it’s a very manageable job. The primary challenges are accessing the module’s location (usually behind the glove box) and carefully handling the electrical connectors. No special tools are needed for the physical swap, but a capable scan tool is required for post-installation procedures.
What happens if I don’t perform the post-installation procedures?
Skipping the ‘Setup SDM Primary Key’ procedure will likely leave the airbag warning light on, as the new BCM and the airbag system (SDM) need to be electronically ‘introduced’. The brake pedal recalibration, if required for your vehicle, ensures the brake lights and stability control systems function correctly. These steps are crucial for safety.
Will this fix my car’s no-start issue?
If the no-start is caused by the BCM’s control over the anti-theft or security system, then yes, this will very likely solve the problem. A failing BCM is a common culprit for security-related starting issues in these vehicles.
Is this part new or used?
This is a high-quality, inspected, and tested recycled OEM part. We ensure its functionality and then program it with the latest GM software for your vehicle, providing a reliable and cost-effective solution.
