Restore Your Vehicle’s Electrical System with a Hassle-Free BCM Solution
Are you battling bizarre electrical issues in your Buick, Chevy, or GMC? Flickering lights, malfunctioning power windows, a temperamental security system, or even a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant frustration. It’s the central nervous system for your car’s comfort and convenience features, and when it fails, chaos ensues.
This isn’t just a replacement part; it’s a complete, streamlined solution. We offer a professional cloning service for this BCM, compatible with part numbers like 13504494 and 13578420. This process eliminates the need for expensive dealership visits, programming fees, and the hassle of getting your vehicle towed. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this fully tested replacement unit. We then ship it back to you, ready for a simple, plug-and-play installation.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2011 Chevy Equinox that came into my shop with a truly baffling set of symptoms. The owner complained that the dome lights would stay on, the radio would randomly shut off, and the remote key fob worked only intermittently. He had already replaced the battery and checked all the fuses. Diagnostics showed a handful of ‘Lost Communication’ codes (U-codes), pointing fingers everywhere. Instead of chasing electrical gremlins for hours, my experience pointed straight to the BCM. We performed a cloning service just like this one, and the replacement 2011 Regal BCM (which shares the same architecture) solved every single issue instantly. It’s a classic case where the central hub, not the individual components, was the root cause.
Is Your Vehicle Showing These Common BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system engaging randomly or preventing the car from starting (anti-theft light on).
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Communication error codes, such as U0140, stored in the system.
- ✔ Complete no-start condition where the starter doesn’t even click.

- Step 2: Ship Us Your Original BCM. Carefully remove your vehicle’s original Body Control Module and package it securely. Ship it to the address we provide.
- Step 3: We Handle the Programming. Once we receive your module, our expert technicians will meticulously transfer all the necessary data to the replacement unit. This ensures seamless compatibility.
- Step 4: Receive & Install. We ship your new, pre-programmed BCM back to you, typically within one business day. Installation is as simple as plugging it in and reconnecting the battery. No extra programming is required.
Important Post-Installation Checks
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up after the new BCM is installed. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag module with the new BCM.
- Brake Pedal Position Relearn: On certain models, the brake pedal position sensor may need to be recalibrated. This is essential for proper brake light and traction control functionality.
Disclaimer: Vehicle systems can vary. For the most accurate procedures for your specific model, always refer to a factory service manual or consult with a qualified automotive technician.

Why do I need to send you my original BCM?
Your original BCM contains the unique software, VIN, and security information for your specific vehicle. By cloning this data to the replacement module, we create a true plug-and-play part that works perfectly with your existing keys and systems, saving you from a costly trip to the dealership for programming.
Is this a difficult part to install?
No. The physical installation is straightforward for anyone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard. Once you receive the cloned module from us, you simply disconnect the battery, unplug the old BCM, plug the new one in, and reconnect the battery. The complex part is the programming, which we handle for you.
Will I have to get new keys made?
Absolutely not. Our cloning service transfers your vehicle’s existing key data. Your current keys will work exactly as they did before, with no additional programming needed.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data for the cloning process. If you have concerns about the condition of your module, please contact us before ordering to discuss the specifics.
Do I need to return my old BCM after installation?
No, there is no core charge for this item. You can keep your original module.
