Restore Full Electronic Functionality to Your Vehicle
Is your Chevrolet Sonic or other GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a no-start condition can often be traced back to a single, critical component: the Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and seemingly unrelated problems. Instead of facing a costly trip to the dealership for a new module and expensive programming, our mail-in programming service provides a simple, effective, and affordable solution.
From the Diagnostic Bay
We recently had a 2016 Chevy Sonic in the shop that was driving its owner crazy. The radio would randomly turn off, the interior lights would flicker while driving, and occasionally, the car wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked the alternator, but the gremlins persisted. After hooking up our diagnostic scanner, we saw multiple communication error codes pointing towards the BCM. Instead of a multi-thousand dollar dealer repair, we performed a cloning service just like this one. We transferred the data from his failing BCM to a replacement unit. After a quick installation, all the bizarre electrical issues were gone. It’s a perfect example of how a failing BCM can mimic a dozen other problems.
Common Symptoms of a Failing BCM
- âś” Intermittent or non-functional power windows, door locks, or mirrors.
- âś” Erratic behavior from interior or exterior lighting (flickering, staying on, or not turning on).
- âś” Malfunctioning windshield wipers or horn.
- âś” False alarms or issues with the vehicle’s security or anti-theft system.
- âś” ‘Service Theft Deterrent System’ or other warning messages on the dash.
- âś” A no-start condition where the engine cranks but won’t fire up due to a security lockout.
- âś” Communication errors with other vehicle modules when scanned with a diagnostic tool.

Post-Installation Procedures
In most cases, the installation is 100% plug-and-play. However, due to the complexity of modern vehicle systems, a couple of minor relearn procedures may be necessary in specific situations:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the critical vehicle-specific data (like VIN, key information, and security settings) from your original BCM and writing it onto a replacement BCM. This makes the replacement module a perfect electronic match for your vehicle, eliminating the need for dealership programming.
Will I need to have this programmed by a dealer after I receive it?
No. Our service makes this part completely plug-and-play. Because we’ve transferred all the data from your original module, your vehicle will recognize it as its own. No additional programming is required.
How long does the entire process take?
Once we receive your original BCM, our programming service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a return tracking number as soon as your programmed module is on its way back to you.
What if my original BCM is too damaged to be read?
In the vast majority of cases, even with significant internal failure, we can still retrieve the necessary data. If for some reason your module’s data is completely inaccessible, we will contact you to discuss options, which may include a full refund of the service fee.
Will my existing keys work with the replacement BCM?
Yes! Because we are cloning your original module’s data, the replacement BCM will recognize all of your currently programmed keys. There is no need for a locksmith or key reprogramming.
