Restore Full Electronic Function to Your GM Vehicle
Is your Chevrolet, GMC, or Cadillac plagued by bizarre electrical issues? Flickering lights, unresponsive power windows, a security system with a mind of its own, or random warning lights are all hallmark symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and unpredictable problems. Simply swapping the module isn’t an option, as a new BCM requires costly and complex programming at a dealership to work with your specific vehicle. Our mail-in programming service for this GM Body Control Module is the definitive, hassle-free solution to get you back on the road quickly and affordably.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra 1500 in the shop that was driving its owner crazy. The dome lights would randomly turn on while driving, the horn would chirp when locking the doors with the fob, and the driver’s power window worked only intermittently. Diagnostic trouble codes pointed to a communication failure within the BCM. The owner was quoted nearly $1,100 by the dealer for a new module, programming, and labor. Instead, we used this exact cloning service. We transferred all the data from his original, faulty BCM to our replacement unit. The installation was a 30-minute job, and every single electrical gremlin was gone. It was a perfect plug-and-play fix that saved the customer hundreds of dollars and a major headache.
Is Your GM Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, there’s a high probability your BCM is the culprit. Proper diagnosis is always recommended, but these are the most common indicators:
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on at all).
- ✔ Power windows, door locks, or mirrors operating intermittently or failing completely.
- ✔ The vehicle’s security system acting up, causing false alarms or no-start conditions.
- ✔ Windshield wipers activating on their own or not responding to the switch.
- ✔ The horn sounding randomly or not working when you press it.
- ✔ Multiple, seemingly unrelated warning lights appearing on the dashboard.
- ✔ Climate control system malfunctions.
How Our Simple Mail-In Programming Service Works
We’ve streamlined the process to be as simple and efficient as possible. Forget about towing your vehicle to the dealer and waiting for appointments. Our service provides you with a fully functional, vehicle-specific BCM that’s ready for installation right out of the box.
- Place Your Order: Complete your purchase through our secure checkout.
- Receive Instructions: We will contact you via email or phone with clear, detailed instructions on how to remove and where to ship your original BCM.
- We Program Your Module: Once we receive your original unit, our expert technicians will extract all the critical data—including VIN, mileage, key data, and vehicle options—and flash it onto the replacement module. This process typically takes just 1-2 business days.
- Plug and Play: We ship the programmed replacement BCM back to you. Simply install it, and your vehicle’s electronic functions will be restored. No additional programming is required.
Important Notes on Installation
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a simple synchronization procedure after the new module is installed. This is common and can typically be performed by a qualified technician with a professional diagnostic tool.
- Airbag System Sync: If the airbag warning light comes on after installation, the ‘Setup SDM Primary Key in BCM’ procedure will need to be performed to sync the system and turn off the light. This is only required if the light is on post-installation.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on some models to ensure proper brake light function and traction control system performance.
Always consult a factory service manual or a qualified technician for guidance. Specific procedures can vary by vehicle.

Frequently Asked Questions
What exactly do I need to ship to you?
You only need to ship your original Body Control Module (BCM). We will contact you with detailed removal and shipping instructions after you complete your purchase.
How long does the programming service take?
Once we receive your original module, the data transfer and programming of your replacement unit typically takes 1-2 business days. We will then ship the ready-to-install module back to you with tracking information.
Is this a guaranteed fix for my vehicle’s problems?
This service corrects issues directly caused by a faulty BCM. It is essential to have your vehicle properly diagnosed by a professional to confirm the BCM is the root cause of the problem before ordering.
Will I need to reprogram my keys?
No. Because we clone the data from your original module, the replacement unit will recognize your existing keys. Your vehicle’s security information is transferred, making the installation seamless.
What if I see an airbag light after installation?
In some GM vehicles, the new BCM needs to be synced with the airbag system (SDM). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed with a professional scan tool by your mechanic.
Do I need to return my old BCM after I receive the replacement?
No, there is no core charge for this part. You can keep your original module.
