Restore Your Vehicle’s Electrical Stability
Are you battling a storm of strange electrical problems in your Buick LaCrosse or other GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or even a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can turn your daily drive into a frustrating guessing game. This isn’t just an inconvenience; it can affect vehicle safety and security.
We offer a straightforward and reliable solution. This is a fully tested Body Control Module, compatible with part number 13501737 and many others, that comes pre-programmed with your vehicle’s original data. By cloning the information from your existing BCM, we eliminate the need for costly dealership programming, key relearns, or complex diagnostic tool setups. It’s the most efficient way to get your car back to 100% functionality.
Case Study: A Tricky Diagnosis
A customer brought in their 2011 Buick LaCrosse with a bizarre list of complaints. The radio would turn on and off, the driver’s side power window wouldn’t work, and the anti-theft light would flash randomly, sometimes preventing the car from starting. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I found a slew of ‘Lost Communication’ codes (U-codes) pointing to the BCM. Instead of a new, unprogrammed module from the dealer which would have cost over $700 after programming and labor, we used our cloning service. We transferred the data from his failing unit to our replacement module. The total repair time, including removal and reinstallation, was under an hour, and it permanently solved every single one of his electrical gremlins.
Common Signs of a Failing BCM
If your vehicle is exhibiting these symptoms, a failing BCM is the likely cause. A bad 2011-2012 LaCrosse BCM can cause system-wide issues that may seem unrelated at first glance.
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or preventing the engine from starting.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or U0100.
- ✔ Wipers activating on their own or not turning on.
- ✔ A dashboard lit up with multiple, unrelated warning lights.
A Straightforward Guide to Installation
Our cloning service makes the physical swap simple. Once you receive your programmed module from us, follow these general steps. For the LaCrosse, the BCM is typically located in the driver’s side kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Original BCM: Access the BCM by removing any necessary trim panels. On the 2011-2012 LaCrosse, this is usually on the left-hand (driver’s) side kick panel area.
- Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that must be depressed. Once disconnected, remove any bolts or clips holding the BCM in place.
- Install the New Module: Seat your pre-programmed replacement BCM in the same location and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Reconnect Power: Reattach the negative battery terminal. The vehicle’s data is already on the module, so no further programming is required.
Important Post-Installation Checks
While our service bypasses the main programming, some vehicle systems may require a simple sync procedure after the BCM is replaced. This is standard for many modern vehicles.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool 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 operation and to prevent issues with the traction control or stability control systems.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any procedure.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the vital data and transfer it to the replacement module. We then ship the plug-and-play BCM back to you.
Do I need to send my keys?
No. Because we are cloning all the data from your original module, including the key and security information, you do not need to send us your keys. The replacement module will work with your existing keys instantly.
What if my original BCM is badly damaged or not communicating?
In most cases, even if the BCM is failing, we can still retrieve the necessary data. If your module is completely destroyed (e.g., by fire or severe water damage), please contact us before ordering to discuss options.
Is this a guaranteed fix for my car’s problems?
This BCM will fix any issues directly caused by a faulty BCM. It is crucial to have your vehicle properly diagnosed to confirm the BCM is the root cause before ordering. This part will not fix issues with other unrelated components.
Is there a core charge?
No, there is no core charge. You can keep your original module after you send it to us for the data cloning service.
