An Expert’s Note on BCM Replacement
From over 20 years of diagnostics, I’ve seen firsthand how a failing BCM can send mechanics and owners on a wild goose chase, replacing perfectly good parts because the symptoms are so misleading. A faulty BCM can mimic a bad fuel pump, a faulty ignition switch, or a wiring short. The real value of a Programmed 25826124 BCM isn’t just the part itself—it’s the certainty. It eliminates the most complex variable, saving you hundreds, if not thousands, in diagnostic fees and unnecessary repairs. This is the most direct path to getting your vehicle back to 100%.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of non-engine-related functions. This includes power windows, locks, lights, the alarm system, wipers, and HVAC controls. When it fails, these systems can behave erratically.
How does the VIN programming process work?
After you place your order, you simply provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the correct GM factory software and vehicle-specific settings onto the BCM before it ships. This ensures it communicates perfectly with your vehicle’s other modules upon installation.
Will I need to perform any procedures after installation?
In some cases, yes. Depending on your specific model, a ‘Setup SDM Primary Key in BCM’ procedure may be needed if the airbag light is on, or a ‘Brake Pedal Position Relearn’ may be required. These procedures are performed with a professional-grade scan tool and are detailed in the factory service manual.
Is this a direct replacement for my original BCM?
Yes. This module is a direct replacement for part number 25826124 and all the other part numbers listed in the description. As long as your original part number is on our list, this unit will fit and function correctly in your vehicle.
What happens if I forget to provide my VIN?
Providing your VIN is a required step for this purchase. We cannot ship your Programmed 25826124 BCM until we receive your VIN, as the programming is essential for the part to function in your vehicle. We will contact you to retrieve this information if it is not provided at checkout.
