Tired of Unpredictable Electrical Problems in Your Buick Lucerne?
If you’re dealing with flickering interior lights, power windows with a mind of their own, or a security system that acts up randomly, you’re likely facing a failing Body Control Module (BCM). As a technician with over two decades of diagnostic experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. The BCM is the central command for your vehicle’s body electronics, and when it starts to fail, the symptoms can be confusing and widespread. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a straightforward and permanent solution. This is a comprehensive Cloning Service for your 2006-2011 Lucerne BCM. Instead of shipping you a blank module that requires expensive dealership programming, we transfer all the critical, vehicle-specific data from your original BCM to this fully tested replacement unit. This process ensures that your vehicle’s identity, key programming, and specific options are perfectly preserved. The result is a true plug-and-play fix that gets you back on the road without the hassle and expense of a dealer visit.
From the Diagnostic Bay: A Lucerne’s Ghostly Glitches
A customer brought in their 2009 Lucerne with a list of bizarre issues: the radio would shut off, the dome light would stay on, and occasionally the car wouldn’t recognize the key fob. They had already replaced the battery and checked the fuses. After connecting my scan tool, I noticed intermittent communication loss codes (U0140) with the BCM. Instead of just failing completely, the module was glitching. By performing a data clone to a replacement BCM, we preserved all the original key data and vehicle settings. The car was back to normal the same day, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Is Your Lucerne Showing These Signs of BCM Failure?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security system engaging without reason or the key fob not being recognized.
- ✔ Erratic behavior from the radio or instrument cluster gauges.
- ✔ A battery that drains overnight with no obvious cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or B1001.

- Step 3: We ship both your original module and the ready-to-install replacement module back to you.
- Step 4: Simply install the replacement BCM in your vehicle. Since it’s an exact clone of your original, no further programming is required for standard operation.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick sync procedure after the BCM is reconnected. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the security handshake between the BCM and the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and stability control function. This is also done with a compatible scan tool.
Disclaimer: We always recommend consulting a factory service manual or a certified mechanic for your specific vehicle. Procedures can vary slightly by year and model.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we extract the unique software and vehicle-specific data (like key information and optional features) from your original BCM and transfer it directly onto the replacement module. This makes the new module an identical twin to your old one, eliminating the need for costly dealership programming.
Why is cloning better than just installing a used BCM from a junkyard?
A used BCM from another vehicle contains the wrong VIN and security information. Installing it will cause a no-start condition or a host of other conflicts. Our cloning service ensures the replacement module is perfectly matched to your car’s electronic systems.
Do I get my original BCM back?
Yes, absolutely. We always return your original module along with the newly programmed replacement unit. We do not keep your original part.
Is this a difficult part to install myself?
For most DIYers with basic tools, the physical installation is straightforward. On the Lucerne, the BCM is typically located on the right side of the dash. The main benefit of our service is that the electronic side of the job is already done for you, making it a plug-and-play installation.
What if my airbag light comes on after I install it?
This is a normal security measure. The BCM and the airbag module (SDM) need to be electronically re-introduced. A mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
