Restore Full Electronic Control to Your Vehicle
Is your 2012-2013 Buick LaCrosse, or another compatible GM vehicle, suffering from strange and unpredictable electrical problems? The Body Control Module (BCM) is the central nervous system for your car’s electronic accessories. When it fails, it can cause a cascade of frustrating issues, from flickering lights to a car that won’t start. This listing is for a replacement BCM, part number 13580696, that is professionally programmed with your vehicle’s original data, providing a seamless, plug-and-play solution.
Symptoms of a Failing 2012-2013 LaCrosse BCM
A faulty BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your BCM may be the culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on at all).
- ✔ Malfunctioning dashboard gauges or warning lights that illuminate for no reason.
- ✔ Problems with the vehicle’s security system, including random alarm activation.
- ✔ The radio or climate control system working incorrectly or not at all.
- ✔ A no-start condition where the engine cranks but won’t turn over due to security system conflicts.
- ✔ Rapid battery drain while the vehicle is off.
From the Diagnostic Bay
We had a 2012 Buick Regal come into the shop with a classic ‘ghost’ problem. The customer complained of a dead battery every morning and interior dome lights that would flicker randomly while driving. They had already replaced the battery and alternator with no success. After a thorough diagnostic, we traced the parasitic draw back to the BCM. It wasn’t properly shutting down accessory power when the car was off. By providing a cloned BCM, we were able to solve the issue without a complicated and expensive trip to the dealer for programming. The customer was back on the road the next day with all systems functioning perfectly.
How Our Simple Programming Service Works
Forget about towing your car to the dealership and paying high fees for programming. Our service is designed to be straightforward and get you back on the road quickly. The process is simple:
- Place Your Order: Purchase this BCM listing. We will then contact you with shipping instructions.
- Ship Your Original BCM: Carefully package and send your original BCM to us. This module contains all the unique data for your vehicle’s specific options and security settings.
- We Transfer the Data: Upon receiving your module, our technicians will perform a full data transfer from your original BCM to the replacement unit. This ‘cloning’ process ensures the new module is a perfect match for your car.
- Receive Your Ready-to-Install BCM: We ship the newly programmed BCM back to you, typically within one business day. Once it arrives, installation is as simple as swapping the modules. No further programming is required.
Installation and Post-Install Considerations
After installing your programmed BCM, your vehicle should return to normal operation. However, in some cases, specific vehicle systems may require a relearn or synchronization procedure. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be needed to ensure proper function of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and climate controls. It acts as a central hub for these systems.
How does this programming service work?
You send us your original BCM. We extract the vehicle-specific data from it and transfer it to the replacement BCM we provide. This makes the replacement module an exact electronic copy, allowing it to work in your car without any additional programming.
Is this a true plug-and-play solution?
Yes, in over 95% of cases. Because we clone your original data, the car recognizes the new module as its own. In rare instances, a simple relearn procedure, like for the airbag or brake pedal sensor, may be needed as outlined above.
What if my original BCM is completely dead or unreadable?
In most cases, even if the BCM is failing, we can still retrieve the necessary data. If your module is severely damaged (e.g., by fire or water) and the data is unrecoverable, we will contact you to discuss other options.
Do I need to return my old BCM after installation?
No. We only need your original BCM for the data transfer service. There is no core charge, and you are not required to send it back after you receive the programmed replacement.
Which part number will I receive?
You will receive a replacement BCM that is fully compatible with the original part number 13580696 and the other listed interchangeable numbers. The physical part number on the unit you receive may vary, but it is guaranteed to be programmed and function correctly for your vehicle.
