Restore Your Vehicle’s Brain without the Dealership Headache
Are you battling frustrating electrical gremlins in your Buick LaCrosse, Chevy Malibu, or other compatible GM vehicle? Intermittent power windows, flickering lights, a security system that acts up, or strange warning messages on the dash are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it fails, it can cause a cascade of confusing problems. For years, the only solution was a costly trip to the dealership for a new module and expensive programming. Not anymore.
We offer a straightforward, reliable programming service that gets you back on the road fast. You simply send us your original BCM, and we professionally transfer all of its critical data—including VIN, mileage, and security information—to this fully tested replacement module. We then ship it back to you, ready for installation. This process ensures a seamless, plug-and-play experience, restoring full functionality without any additional programming required on your end.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Chevy Malibu with a list of bizarre symptoms: the radio would turn off randomly, the interior dome light would flicker while driving, and the car occasionally wouldn’t recognize the key fob. A scan showed multiple U-codes, specifically U0140 (Lost Communication With Body Control Module). Instead of a $900+ bill from the dealer for a new module and programming, they opted for our cloning service. We transferred the data from their failing BCM to our replacement unit. They installed it themselves in under 30 minutes in their driveway, and every single electrical issue was resolved. It’s a perfect example of how this service saves both time and money.
Common Signs of a Failing BCM
If your vehicle’s BCM is on its way out, you’ll likely notice one or more of these issues. In my shop, these are the symptoms I see most often when diagnosing a faulty 2014-2016 LaCrosse BCM or related GM module.
- ✔ Power windows, locks, or mirrors operate erratically or not at all.
- ✔ Instrument cluster lights flicker, or gauges behave abnormally.
- ✔ Headlights, taillights, or interior lights don’t work correctly.
- ✔ The anti-theft or security system light is on, preventing the car from starting.
- ✔ Communication error codes are present (e.g., U0140, U0155).
- ✔ The key fob is not detected, or the push-to-start system fails intermittently.
- ✔ The horn sounds randomly or doesn’t work when pressed.
A Straightforward Guide to Your BCM Installation
Our cloning service makes the physical swap simple. Once you receive your pre-programmed module from us, follow these general steps. The BCM in the LaCrosse is typically located behind the driver’s side (LH) kick panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the Module: Remove the necessary trim panels (usually the driver’s side kick panel or lower dash trim) to access the original 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 Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, etc.—to confirm proper operation.
Important Post-Installation Information
In most cases, this module is a direct plug-and-play solution. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required in specific situations:
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: On some models, a Brake Pedal Position (BPP) sensor relearn might be necessary to ensure the brake lights and stability control systems function correctly. This is also performed with a capable diagnostic tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the process.

Frequently Asked Questions
How does this programming service work?
How does this programming service work?
It’s simple. After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, we extract the vehicle-specific data and transfer it to the replacement module. We then ship the newly programmed module back to you, ready for installation.
Do I have to send my original part?
Yes. Cloning the data from your original module is the only way to guarantee 100% compatibility and avoid the need for expensive programming at a dealership. This ensures your vehicle’s security system and all options work correctly.
Is there a core charge or do I need to return the part after?
There is no core charge for this service. We only need your original module to perform the data transfer. You can keep your original, non-functional module after the service is complete.
Why is my airbag light on after installing the new BCM?
This can happen occasionally. It means the BCM and the Airbag Control Module (SDM) need to be electronically re-synced. A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
How long does the entire process take?
We typically program and ship your replacement BCM within 24-48 hours of receiving your original module. The total time will depend on shipping transit times to and from our facility.
