Is Your Buick LaCrosse Experiencing Strange Electrical Issues?
If your 2014-2016 Buick LaCrosse, or another compatible GM vehicle, is suffering from a host of baffling electrical problems, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to your interior lighting, security system, and communication between other modules. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated symptoms that can be difficult to diagnose.
Replacing a BCM has traditionally been a costly and inconvenient process, requiring a trip to the dealership for expensive programming and key relearning procedures. Our unique programming service eliminates that hassle entirely. We provide a fully functional, tested replacement BCM that is a direct-fit for your vehicle. By cloning the data from your original module, we create a true plug-and-play solution. This means no additional programming, no security relearn, and no unexpected trips to a mechanic. You can restore your vehicle’s full functionality right in your own driveway.
From the Diagnostic Bay
We had a customer with a 2015 Chevy Malibu whose car was acting possessed. The horn would honk randomly, the interior lights would flicker while driving, and the key fob worked intermittently. They had already replaced the battery and checked all the fuses, but the gremlins persisted. After a quick scan, we saw multiple communication error codes pointing towards the BCM. Instead of sending them to a dealer for a new module and a hefty programming bill, we performed our cloning service. We transferred the data from their faulty BCM to one of our replacement units. After a simple 15-minute installation, every single issue was resolved. The car was back to normal, and the customer saved hundreds of dollars and a major headache.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Key fob not working or only working sporadically.
- ✔ Vehicle’s security system alarming for no reason or not arming correctly.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, some vehicle systems may require a simple recalibration after the BCM is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
How does this cloning and programming service work?
After you place your order, you will ship your original Body Control Module to us. We then extract the vehicle-specific data (like VIN and key information) and flash it onto the replacement module we provide. We then ship the programmed replacement module back to you, ready for plug-and-play installation.
Do I need to have a dealer program this BCM?
No. The entire point of our service is to avoid dealer programming. Because we clone the data from your original part, the replacement BCM is a true plug-and-play solution. Your vehicle will recognize it as the original module.
How long does the entire process take?
Once we receive your original module, our service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We will send you a tracking number as soon as your programmed module is on its way back to you.
Will my original keys work with the new module?
Yes! Since we transfer all the original security information from your old BCM, your existing keys will work exactly as they did before, with no need for reprogramming.
What if this doesn’t fix my problem?
While a faulty BCM is the cause of many electrical issues, proper vehicle diagnosis is key. We guarantee the function of our module and the integrity of the data transfer. If your issues persist, it may indicate a problem elsewhere in the vehicle, such as wiring or another module.
