Restore Control and Eliminate Electrical Headaches
Are you dealing with baffling electrical issues in your 2010 Buick Allure, LaCrosse, or Chevy Camaro? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect vehicle security and safety. We offer a straightforward, reliable solution: a replacement BCM, part number 13577268, that arrives at your door fully programmed and ready for installation.
Our unique cloning service eliminates the biggest hurdle in BCM replacement: the expensive and time-consuming trip to the dealership. Simply send us your original BCM. Our expert technicians will transfer all the critical vehicle-specific data—like the VIN, security information, and other settings—to this replacement unit. The result is a true plug-and-play module that restores full functionality to your vehicle. By choosing this service, you get a cost-effective and efficient fix for your 2010 Allure BCM issues without the need for specialized programming tools.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. I’ve seen these symptoms countless times in the shop, often accompanied by communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other U-series codes.
- ✔ Intermittent or non-working power windows, door locks, and interior lights.
- ✔ The security system or alarm activates randomly or prevents the car from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Windshield wipers behaving erratically (turning on by themselves or not turning off).
- ✔ Instrument cluster warning lights (like the airbag or ABS light) illuminating for no reason.
- ✔ Key fobs that suddenly stop working.
- ✔ A complete no-start condition where the vehicle has power but won’t crank.
From the Diagnostic Bay: The Ghost in the Camaro
A customer brought in a 2010 Camaro with what he called “automotive poltergeists.” The dome light would fade in and out while driving, the horn would chirp when he hit a bump, and sometimes the driver’s side window wouldn’t roll down. He’d already replaced the battery and checked all the fuses. Diagnostics showed no hard codes, just intermittent communication loss with various modules. After confirming solid power and ground to the BCM, we suspected the module itself was failing internally. Instead of a costly new unit and programming from scratch, we performed a cloning service just like this one. After installing the cloned BCM, every single ghost in his machine vanished. It’s a perfect example of how a failing 2010 Allure BCM (or in this case, a Camaro BCM) can create a host of seemingly unrelated issues.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down before starting work.
- ✔ Locate the BCM: On the 2010 Allure and LaCrosse, the BCM is located in the driver’s side (LH) kick panel area. For the 2010 Camaro, you’ll find it behind the passenger side (RH) of the dashboard.
- ✔ Access the Module: You may need to remove a plastic trim panel or glove box to gain clear access to the BCM.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your newly programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- ✔ Reconnect and Test: Reinstall any trim panels you removed, reconnect the negative battery terminal, and start the vehicle. Test all functions like lights, locks, windows, and wipers to confirm the repair.
Important Post-Installation Steps
In some cases, additional synchronization procedures may be required after installation. These are standard vehicle security and safety handshakes between modules.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light operation and traction control functionality, a brake pedal position sensor relearn might be necessary. This can also be done with a capable diagnostic tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning process 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 extract the unique data and flash it onto the replacement module. We then ship the programmed module back to you, typically within 1-2 business days.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which is what we transfer during the cloning process.
Is this a plug-and-play solution?
Yes, because we clone your original data, this module is designed to be plug-and-play. It eliminates the need for any additional programming with dealership tools after installation. However, as noted, some vehicles may require minor relearn procedures for systems like the airbag or brake sensor.
What if the airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge for my old BCM?
No, there is no core charge. We need your original module to perform the programming service, but you are welcome to keep it afterward if you wish.
