Restore Full Functionality to Your Vehicle’s Electronics
Are you battling persistent and unpredictable electrical problems in your 2010 Buick Allure, LaCrosse, or Chevrolet Camaro? Issues like flickering lights, non-responsive power windows and locks, or a security system that acts on its own are often symptoms 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 create a cascade of frustrating and difficult-to-diagnose problems. This listing offers a straightforward, reliable solution: a replacement BCM, part number 13578421, that arrives at your door fully programmed and ready for installation.
We recently had a 2010 Camaro in the shop with a classic ‘ghost in the machine’ problem. The owner complained that the interior lights would stay on, draining the battery overnight, and the radio would randomly change stations. He had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly and time-consuming replacement at the dealership, we used our cloning service. By transferring the data from his original, faulty BCM to a quality replacement unit, we had him back on the road the same day with all electrical gremlins banished. This is the exact service we offer here—a proven, effective repair that saves you time and money.
Diagnosing a Faulty 2010 Allure Body Control Module
The BCM manages a wide array of non-engine-related functions. Its failure can manifest in numerous ways, often intermittently at first, making it tricky to pinpoint. If your vehicle is experiencing several of the issues below, your BCM is the most likely culprit. Our programming service for the 2010 Allure Body Control Module ensures the replacement unit integrates seamlessly with your vehicle’s existing systems.
Common Symptoms of BCM Failure
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) flicker, stay on, or fail to turn on.
- ✔ The vehicle’s security system or keyless entry fails to work correctly.
- ✔ The horn sounds unexpectedly or doesn’t work when pressed.
- ✔ Dashboard warning lights appear for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Wipers operate randomly or won’t turn off.
- ✔ The vehicle won’t start, and the security light is illuminated, indicating an immobilizer issue.
Our Plug-and-Play Programming Service Explained
Dealerships will sell you a new BCM that requires expensive, vehicle-specific programming with their proprietary tools. Our service bypasses this hassle completely. We perform a data transfer, also known as cloning, from your original BCM to this replacement unit. This process copies all the critical information—including your vehicle’s VIN, key fob data, and specific electronic settings—onto the replacement module. The result is a true plug-and-play part. There is no need for additional programming or a trip to the dealer.
How it works:
- Purchase this service: Complete your order through our secure checkout.
- Ship us your module: We will contact you with clear instructions on how to package and ship your original BCM to our facility. Please ensure your contact information is up-to-date.
- We program the replacement: Upon receiving your module, our technicians will transfer all necessary data to the replacement BCM.
- We ship it back: We ship the programmed replacement BCM back to you, typically within 1-2 business days. You will receive tracking information once it’s on its way.
Post-Installation Procedures
While our service makes the installation as simple as possible, some GM vehicles may require minor recalibration procedures after the BCM is reconnected. These are standard steps that can often be performed with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, the Brake Pedal Position Sensor may need to be recalibrated to ensure proper brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How does this programming service work?
You send us your original BCM. We then extract the unique data from it and transfer it to the replacement module. This makes the replacement a plug-and-play part, perfectly matched to your car’s specific configuration and security settings.
Why do I need to send in my original module?
Your original module contains vital information like the Vehicle Identification Number (VIN) and security data for your keys. By cloning this data, we ensure the replacement module works seamlessly with your existing keys and systems, avoiding a costly trip to the dealership for programming.
Will I need to program this BCM at the dealership?
No. Our service completely eliminates the need for any additional programming. Once you receive the module back from us, you can install it, and it will function correctly.
What are the most common signs of a failing BCM in my 2010 Camaro/LaCrosse/Allure?
The most common symptoms include erratic behavior of interior/exterior lights, power locks and windows not working, false dashboard warnings, and security system malfunctions. A no-start condition with the security light on is also a strong indicator.
What happens if the airbag light comes on after installation?
This indicates the BCM needs to be synchronized with the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
