Restore Full Functionality to Your Vehicle’s Electronics
Is your 2011-2012 Buick LaCrosse, or another compatible GM vehicle, suffering from bizarre and frustrating electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are often symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it fails, it can cause a cascade of seemingly unrelated issues. This programmed Body Control Module, compatible with part number 13582396 and many others, is the definitive solution to restore your vehicle’s electrical systems to factory-perfect condition.
We had a 2011 Chevy Equinox come into the shop that was driving the owner crazy. The radio would randomly change stations, the interior dome light would stay on, and the power door locks would engage and disengage while driving. The customer had already replaced the battery and checked all the fuses. After hooking up our professional scan tool, we saw multiple communication errors pointing towards a network failure. We traced the issue to the BCM, which was sending faulty signals across the vehicle’s network. Instead of a costly trip to the dealer for a new module and programming, we provided a cloned BCM. The customer swapped it out in their driveway, and every single electrical gremlin vanished instantly. It’s a common story with these modules, and a pre-programmed unit is the most efficient fix.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle’s security system or keyless entry malfunctioning.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Wipers or horn activating unexpectedly.
- ✔ In some cases, a no-start condition due to security system communication failure.
The Simple, Plug-and-Play Solution
Forget expensive dealership visits and the hassle of vehicle towing and programming appointments. Our professional cloning service makes this repair straightforward and accessible. Here’s how it works: you purchase this service, send us your original BCM, and we transfer all the critical vehicle-specific data (including VIN, mileage, and key information) to this replacement unit. We then ship the fully programmed module back to you. The result is a true plug-and-play component. Simply install it, and you’re back on the road. No additional programming or calibration is required for basic vehicle operation.

Installation and Post-Install Considerations
Physical installation is typically simple, involving disconnecting the battery and swapping the module, which is often located in the driver’s or passenger’s side kick panel or dash area. After installation of your programmed 2011-2012 LaCrosse BCM, your vehicle should start and run correctly. However, in some vehicles, a couple of additional steps may be needed:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control functionality.
These procedures are not always required but are important to be aware of. Always consult a factory service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the essential, vehicle-specific software and security data from your original BCM and writing it directly onto a replacement module. This makes the replacement unit an exact digital copy of the original, allowing it to work in your vehicle without any further dealer programming.
Why do I need to send you my original BCM?
Your original BCM contains the unique VIN, key codes, and option configurations for your specific car. We need to extract this data to program the replacement. Without it, the new module would not be able to communicate with the other computers in your vehicle.
Is this module difficult to install?
The physical replacement of the BCM is generally straightforward for someone with basic mechanical skills. It’s usually located behind a kick panel or under the dash and involves unplugging a few connectors and removing some bolts or clips. The main benefit of our service is that the complex software side is completely handled for you.
What if my original BCM is completely dead or water damaged?
In many cases, even if the BCM is non-functional, we can still extract the necessary data from the memory chip. Please contact us before ordering if your module has severe physical or water damage so we can assess the likelihood of a successful data recovery.
Will I need to go to the dealership after installation?
No! Our cloning service is designed to completely eliminate the need for dealer programming. The module you receive will be plug-and-play. The only exception is the potential need for a post-install relearn procedure like for the airbag system, which can be done by most independent repair shops with a high-end scan tool.
What does ‘No Core Charge’ mean?
It means you do not have to pay an extra deposit for your old part. While we need your original module to perform the programming service, you are not required to return it for a core refund.
