Is Your Buick Lucerne Experiencing Strange Electrical Problems?
If your 2006-2011 Buick Lucerne is plagued by baffling electrical issues, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s electronic accessories, controlling everything from your power windows and locks to the interior lights and security system. When it starts to fail, it can create a host of frustrating and unpredictable problems that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2008 Buick Lucerne come in with an intermittent no-start condition. The battery was good, the starter checked out, but every few days, the key would turn and… nothing. After checking the basics, we hooked up the scan tool and noticed communication errors with the body control module. The BCM wasn’t properly recognizing the key’s security chip, preventing the car from starting. Swapping in a VIN-programmed BCM like this one resolved the issue completely, saving the customer from being stranded again.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system acting up, or the alarm going off randomly.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Intermittent no-start conditions where the engine won’t crank.
- ✔ Problems with the radio or climate control functions.

Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require minor post-installation procedures. These can typically be performed by a local mechanic with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your car that manages and controls many of the electronic accessories not related to the engine, such as power windows, lights, door locks, the security system, and climate controls.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and settings for your car’s specific features. This ensures compatibility and proper function upon installation.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. Because we pre-program the unit, you avoid complex programming. However, some vehicles may require minor follow-up procedures as noted in the description.
Do I need to send my old part back?
No, there is no core charge for this module. You can keep your original part.
What if my airbag light is on after I install the new BCM?
This is a known possibility. A technician with a professional scan tool will need to perform a simple ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system with the new module and turn off the light.
