Restore Full Electrical Function to Your GM Vehicle
Are you battling strange and frustrating electrical problems in your 2006-2011 Buick Lucerne or another compatible GM vehicle? Issues like flickering interior or exterior lights, malfunctioning power windows and locks, a security system that acts up, or even a no-start condition can often be traced back to a single point of failure: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and intermittent symptoms. This replacement Body Control Module, part number 25826125, is the definitive solution to get your car back to operating as it should.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system or anti-theft light flashing, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with other modules, leading to warning lights on the dash.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ Inconsistent key fob operation.
Why Choose Our Pre-Programmed 2006-2011 Lucerne BCM?
The biggest hurdle in replacing a modern vehicle computer is the need for expensive, dealer-specific programming. We eliminate that step entirely. When you purchase this module, we will flash it with the latest official GM software updates using the unique Vehicle Identification Number (VIN) you provide. This ensures that the BCM is perfectly matched to your vehicle’s specific options and configuration. It’s a true plug-and-play solution that saves you a trip to the dealership and the high costs associated with their programming services. Simply install the module, and you’re ready to go. In some cases, minor post-installation procedures, such as an airbag system sync or brake pedal position relearn, may be required, but the core functionality will be restored immediately.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features. This includes power windows, locks, lights, the security system, wipers, and climate control functions.
Is this part truly plug-and-play?
Yes, for the vast majority of functions. We program the module to your vehicle’s VIN before shipping, which handles the main security and operational setup. In some cases, a simple relearn procedure for the brake pedal position or airbag system might be needed, which can be done with a capable scan tool.
How do I provide you with 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 order until we receive this information, as the programming is essential.
What if my airbag light is on after installation?
This is a common occurrence. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional diagnostic tool to sync the modules and turn off the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this BCM fix my specific problem?
This module will correct any issues directly caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of your problem before ordering.
