Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing a host of strange and frustrating electrical problems in your Buick Lucerne or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or persistent warning messages on your dash are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body-related electronic features, and when it malfunctions, it can disrupt multiple systems at once. This replacement Body Control Module is the definitive solution to restore your vehicle’s proper operation and peace of mind.
This isn’t just a part in a box. We provide a comprehensive service that makes your repair as simple as possible. Each module is professionally programmed with the latest GM software updates, specifically matched to your vehicle using your VIN. This critical step ensures seamless integration and functionality right out of the box, saving you from expensive programming fees and a trip to the dealership. Simply provide your VIN after purchase, and we’ll handle the rest, shipping you a part that is ready for installation.
Common Symptoms of a Failing 2006-2011 Lucerne BCM
If you’re noticing any of the following issues, a faulty BCM is the likely culprit:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security system acting up, including false alarms or a “Service Theft System” message.
- ✔ Instrument cluster gauges behaving erratically or displaying incorrect information.
- ✔ Key fob not working reliably or at all.
- ✔ Communication errors when a mechanic tries to scan the vehicle’s computer systems.
- ✔ A battery that drains overnight with no other obvious cause.
Installation and Post-Install Procedures
While installation is straightforward for many DIYers and all professional technicians, some GM vehicles require additional steps after the new BCM is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control function, a brake pedal position sensor relearn may be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls your vehicle’s body-related electronics. This includes power windows, locks, lights, security system, wipers, and instrument panel functions.
Is this BCM ready to install?
Yes, it is. We program the module to your vehicle’s specific VIN before shipping it to you. This ensures it’s ready for installation, though some models may require the simple relearn procedures mentioned above.
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 your part until we receive this information.
What if the airbag light is on after I install the BCM?
This is a normal possibility. It means the BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep your original module.
