End the Electrical Chaos in Your GM Vehicle
Is your Chevrolet, Buick, or GMC acting possessed? Flickering lights, windows that won’t roll down, a security light that stays on, or worse—an intermittent no-start condition that leaves you stranded. These are classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it creates a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can be a major disruption to your daily life.
This listing is for a professionally programmed Body Control Module, compatible with part number 13583450 and many others. We solve the biggest headache of BCM replacement: the expensive and time-consuming trip to the dealership. Our unique cloning service makes this a simple, plug-and-play repair. You send us your original BCM, and we transfer all its critical data—including VIN, key information, and vehicle-specific settings—to this replacement unit. When you get it back, it’s ready to install without any further programming.
I recently had a 2011 Chevy Equinox in the bay with a textbook BCM failure. The customer complained that sometimes the car wouldn’t start, the radio would cut out, and the power locks worked intermittently. Scanning it revealed a slew of communication codes (U-codes), pointing to a network problem. After verifying power and ground at the BCM, we confirmed the module itself was the culprit. Instead of a costly new module and hours of programming at the dealer, a cloned BCM had them back on the road the next day for a fraction of the cost. These modules are the hub for so many systems; when they fail, the symptoms can seem random, but they almost always trace back to this central point.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Power windows, door locks, or interior lights not working or operating erratically.
- ✔ The anti-theft or security light is illuminated on the dash.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound (not a dead battery).
- ✔ Diagnostic trouble codes (DTCs) related to communication failures, such as U0100, U0140, or other U-codes.
- ✔ Horn, wipers, or other accessories activating on their own.
- ✔ Inconsistent instrument cluster behavior.
Your Straightforward BCM Swap Guide
Our cloning service makes the physical installation a breeze. Once you receive the programmed module from us, you can get your vehicle running in under an hour.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate Your BCM: On the 2011 Chevy Volt, the BCM is located in the right-hand (passenger side) of the engine compartment. For other models, it’s typically in the driver’s side kick panel or under the dash. Refer to your owner’s manual or a quick online search for the exact location on your vehicle.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the Programmed Module: Mount the new BCM in place and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock.
- Reconnect and Test: Reconnect the negative battery terminal. Start your vehicle and test all functions: lights, locks, windows, radio, etc., to confirm the repair was successful.
Important Post-Installation Information
While our service eliminates the need for initial programming, some GM vehicles require a relearn or sync procedure for specific systems after a BCM is replaced.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Procedures can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we read the essential software and security data from your original, failing BCM and write it directly onto a replacement module. This makes the new module an exact electronic copy of the old one, allowing it to work in your vehicle without any additional programming from a dealer.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle is locked to that vehicle’s VIN and security system. It will not start or operate your car. Our service provides a fully functional, programmed module that is ready for installation, saving you the significant cost and hassle of dealer programming.
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 your original BCM, and we transfer that information directly during the cloning process.
How long does the programming service take?
Once we receive your original module, our technicians typically complete the cloning process and ship your ready-to-install BCM back to you within 1-2 business days. We will provide you with a return tracking number as soon as it ships.
What if the airbag light comes on after I install it?
This is a possibility on some GM models. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge for this part?
No, there is no core charge. We only need your original module to perform the data transfer service. You can keep your old module after the service is complete.
