Restore Your Vehicle’s Functionality with a Pre-Programmed BCM
If you’re dealing with bizarre electrical issues in your 2013 Chevrolet Spark—like power windows with a mind of their own, flickering dash lights, or a car that refuses to start—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM). A trip to the dealership can mean hundreds of dollars in diagnostic fees, parts costs, and programming charges. We offer a straightforward, reliable, and cost-effective solution. This listing is for a replacement BCM that arrives at your doorstep fully programmed and ready for installation. We transfer the critical data from your original BCM to this replacement unit, making the process as close to plug-and-play as possible.
Common Signs of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Intermittent no-start or no-crank conditions, even with a good battery.
- ✔ Dashboard warning lights appearing randomly or staying illuminated.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
- ✔ Horn honking unexpectedly or not working at all.
A Technician’s Notebook: The Case of the Haunted Spark
A customer brought in a 2013 Chevy Spark with a list of complaints that sounded like the car was possessed. The radio would switch off, the dome light would flicker while driving, and occasionally, the car just wouldn’t start. They had already replaced the battery to no avail. My initial scan showed a slew of communication loss codes with various modules. In my experience, when you see that many unrelated systems acting up, the central hub—the BCM—is the prime suspect. After confirming power and ground to the BCM were solid, we knew the module itself was failing internally. Instead of a costly new unit and hours of programming, a pre-programmed module like this one is the exact fix we’d use. It solves the problem efficiently, getting the customer back on the road without the dealership hassle.
Your Straightforward Guide to Installation
- ✔ Step 1: Locate and Remove Your Original BCM. On the 2013 Spark, the BCM is typically found in the left lower a-pillar area. Be sure to disconnect the negative battery terminal before starting.
- ✔ Step 2: Ship Us Your Module. After you place your order, we will contact you with simple instructions and a shipping address. Securely package your original BCM and send it to us.
- ✔ Step 3: We Handle the Programming. Once we receive your module, our technicians will professionally transfer all necessary vehicle-specific data to the replacement BCM. This ensures compatibility with your keys, security system, and vehicle options.
- ✔ Step 4: Install Your Programmed BCM. We ship your new, ready-to-install BCM back to you. Simply plug in the connectors, reconnect your battery, and start your vehicle.
- ✔ Step 5: Perform Post-Installation Checks. In some cases, minor relearn procedures may be needed. Please see the ‘Important Technical Notes’ section below for details.
Important Technical Notes & Potential Procedures
While our programming service makes this a direct-fit solution, certain vehicle systems may require a ‘handshake’ with the new BCM. This is normal. After installation, you may need to perform the following:
- Airbag System Sync: If the airbag warning light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control function, a brake pedal position sensor recalibration might be necessary.
Disclaimer: Specific procedures can vary. Always consult your vehicle’s factory service manual or a certified technician for guidance.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple! After your purchase, we’ll email you instructions to ship your original BCM to us. Once we get it, we clone the data to the replacement module and ship it back to you, usually within one business day. This process ensures the replacement BCM is a perfect match for your car’s specific configuration.
Do I need to send my keys?
No, you do not need to send us your keys. All the necessary immobilizer and key data is stored within your original BCM, which is what we transfer to the new unit.
Is this a plug-and-play part?
Yes, this is designed to be a plug-and-play solution. Because we clone your original module’s data, you avoid the need for expensive programming by a dealer. In some rare cases, a simple relearn procedure might be needed as detailed in our description.
What is your policy on the original BCM?
There is no core charge for this service. After we have cloned the data, we will ship your original BCM back to you along with the newly programmed replacement unit. You can keep it as a spare.
Will this fix my no-start problem?
If your no-start issue is caused by a faulty BCM (e.g., security system malfunction, no communication), then this part is the correct solution. It’s crucial to properly diagnose the BCM as the source of the problem before ordering.
