Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your Cadillac or Chevrolet? Flickering lights, malfunctioning power windows, a dead instrument cluster, or even a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and door locks to security systems and climate control. When it fails, it can cause a cascade of confusing and disruptive problems. Dealerships often quote exorbitant prices for a new module, followed by additional costs and delays for programming. Our service offers a direct, cost-effective, and hassle-free alternative.
The Simple, Reliable Fix: Our BCM Programming Service
This listing is for a 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, retaining all original settings, key programming, and vehicle-specific configurations. The result is a true plug-and-play module that eliminates the need for expensive dealership tools or post-installation programming. The process is straightforward: you purchase this service, ship your original BCM to us, and we handle the rest. We’ll meticulously transfer the data to the replacement unit and ship it back to you, ready for installation.
From the Diagnostic Bay
We recently had a 2014 Chevy Sonic in the shop with a classic case of BCM failure. The owner reported that the turn signals would work intermittently, the radio would randomly shut off, and the dome light had a mind of its own. After confirming power and grounds to the BCM were good, we diagnosed a faulty internal processor. Instead of a costly new module and a full vehicle reprogram at the dealer, the owner opted for our cloning service. We received his old BCM, transferred the data to a replacement unit, and shipped it back. He installed it himself in under an hour, and all the bizarre electrical issues were gone. It’s a perfect example of how this service saves customers time, money, and the headache of a dealership visit.
Common Symptoms of a Failing BCM
- âś” Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- âś” Power windows, door locks, or mirrors not working correctly.
- âś” Instrument cluster gauges behaving erratically or not working at all.
- âś” The vehicle’s security system malfunctioning or preventing the car from starting.
- âś” Intermittent operation of the radio, climate controls, or other accessories.
- âś” Multiple, unrelated warning lights appearing on the dashboard.
- âś” Complete no-start condition where the starter does not engage.

Installation and Post-Installation Notes
Once you receive your Programmed BCM 13580689, installation is as simple as disconnecting the battery, removing the old module, and plugging in the new one. However, in some GM vehicles, additional synchronization procedures may be required to ensure all vehicle systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure accurate brake light operation and proper function of the traction control and stability systems, a brake pedal position sensor relearn might be necessary. This can also be performed with a capable diagnostic tool.
Disclaimer: Specific procedures can vary by exact vehicle model and trim. Always consult a factory service manual or a qualified technician for detailed guidance.
Frequently Asked Questions
How does this programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique data and transfer it to the replacement module. We then ship the newly programmed module back to you, ready for installation.
Why is programming necessary for a BCM?
The BCM is programmed with your vehicle’s specific VIN, security information (key data), and optional features. A non-programmed module from another vehicle will not work correctly and will likely prevent the car from starting. Our service ensures the replacement is a perfect match.
Is this a plug-and-play solution?
Yes, in over 95% of cases. Because we clone your original data, the module is ready to be installed and function without any further programming. In rare cases, as noted above, a simple relearn procedure like an airbag sync may be needed.
What is the turnaround time?
We pride ourselves on a fast turnaround. The programming service is typically completed within 1-2 business days of us receiving your original module. Return shipping tracking will be provided as soon as it’s on its way back to you.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the original BCM itself. We transfer this data directly, so your existing keys will work seamlessly with the replacement module.
