Restore Full Functionality to Your Vehicle’s Electronics
Is your Cadillac, Chevy, or GMC plagued by bizarre electrical issues? Flickering lights, malfunctioning power windows, a stubborn security system, or random warning messages are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and unpredictable problems. Dealerships often charge a fortune for a new module plus hours of labor for programming. Our professional programming service offers a reliable and cost-effective solution.
The Perfect Plug-and-Play Solution
This is not just a replacement part; it’s a complete, ready-to-install solution. We provide a quality replacement BCM that is professionally programmed using the data from your vehicle’s original module. This cloning process ensures that the replacement unit is a perfect digital match for your car. It retains your original Vehicle Identification Number (VIN), mileage, security information, and all factory-programmed options. The result is a truly plug-and-play module that requires no additional dealership programming, saving you time, money, and hassle.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 in the shop with the most baffling electrical gremlins. The radio would cut out, the dome light would flicker at random, and worst of all, the truck would intermittently refuse to start, displaying a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked all the main grounds. After extensive testing of the communication networks, we isolated the fault to an internal failure in the BCM. It was corrupting the low-speed data bus, causing chaos across multiple systems. A cloned GM Body Control Module like this one was the answer. Once installed, every single issue was resolved instantly. The customer avoided a tow to the dealer and saved hundreds on diagnostic and programming fees.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The horn sounding unexpectedly or failing to work when pressed.
- ✔ Security system faults, anti-theft light illumination, and no-start conditions.
- ✔ Windshield wipers activating on their own or not responding to the switch.
- ✔ Inaccurate readings or dead gauges on the instrument panel.
- ✔ A multitude of communication error codes (U-codes) stored in the system.
- ✔ Remote keyless entry (RKE) system failure.
Your Simple, Professional Programming Service
Our process is designed to be as straightforward as possible:
- Place Your Order: Complete your purchase through our secure checkout.
- Receive Instructions: We will contact you via email with detailed instructions on how to safely remove and ship your original BCM to our facility.
- We Program Your Module: Once we receive your original module, our expert technicians will perform a full data transfer to the replacement unit. This critical step ensures all vehicle-specific settings are preserved.
- Receive Your Ready-to-Install BCM: We ship the newly programmed BCM back to you, typically within 24-48 hours of receiving your original. Tracking information will be provided so you know exactly when it will arrive.
Installation and Post-Installation Notes
Installation is a direct swap. Simply disconnect the vehicle’s battery, locate your old BCM (often found under the steering column or in the driver’s side dash area), and replace it with the programmed unit we send you. In some cases, minor post-installation procedures may be required:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This syncs the airbag system with the new BCM and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does this programming service work?
You purchase this service and send your original BCM to us. We extract the vehicle-specific data (like VIN, keys, and options) and flash it onto the replacement BCM. We then send the ready-to-install BCM back to you.
Why is cloning my original BCM better than just buying a used one?
A standard used BCM will not work in your vehicle because it’s programmed to the donor car. This causes security system conflicts and feature mismatches. Our cloning service makes the replacement a perfect digital copy of your original, ensuring a seamless, plug-and-play installation without any extra programming.
Will I need to take my car to the dealer after installation?
No. Our service is designed to completely eliminate the need for dealer programming. The module will arrive ready for installation. In rare cases, a simple relearn procedure as noted above may be required.
What data is transferred from my old BCM?
We transfer all critical data, including the VIN, immobilizer/security key data, mileage information, and RPO codes that dictate your vehicle’s specific options (like power seats, sunroof, etc.).
What if my original BCM is completely dead or unreadable?
In many cases, even with significant internal damage, we can still recover the necessary data. If your module is unrecoverable, we will contact you to discuss alternative options.
How long does the entire process take?
Once we receive your module, our programming service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility.
