Restore Your Truck’s Core Electrical Functions
Are baffling electrical issues turning your powerful 2015 Sierra Denali 3500 into a source of daily frustration? When the Body Control Module (BCM) begins to fail, it can trigger a cascade of problems that seem unrelated, from flickering lights and malfunctioning power windows to security system faults and even a no-start condition. This isn’t just an inconvenience; it’s a compromise on the reliability you depend on. We offer a definitive, hassle-free solution: a professionally programmed 2015 Sierra 3500 BCM replacement that gets you back on the road with confidence.
Common Symptoms & Your Solution
A failing BCM can manifest in numerous ways. You might be experiencing:
- Interior or exterior lights that won’t turn on or off
- Power windows, locks, or mirrors operating erratically or not at all
- The security system engaging randomly or preventing the engine from starting
- Warning lights on the dash with no apparent cause
- Communication errors with other vehicle modules (DTCs like U-codes)
Our mail-in cloning service is the most effective way to solve these problems. We transfer the vital data—including VIN, mileage, and key information—from your original BCM to this quality replacement unit. The result is a truly plug-and-play module, eliminating the need for expensive and time-consuming programming at a dealership.

- ✔ Guaranteed Performance: This unit is backed by our one-year replacement warranty.
Expert Insight: Why Cloning is Crucial
In modern trucks like your Sierra Denali, the BCM is the central hub for dozens of electronic systems. Simply installing a used BCM from another vehicle will cause major conflicts, as it contains the wrong VIN and security data. This can immobilize your vehicle completely. Our professional cloning service isn’t just a convenience; it’s a critical procedure that ensures all vehicle systems communicate correctly, just as the factory intended. This is the proper way to perform a programmed 2015 Sierra 3500 BCM replacement.
Simple Mail-In Service Process
After your purchase, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is up to date. Once we receive your module, our technicians will perform the data transfer and ship your programmed replacement BCM back to you, typically within 2-3 business days. You will receive tracking information as soon as it ships.
Post-Installation Procedures
While this module is designed for plug-and-play installation, some vehicles may require minor recalibration procedures after the BCM is replaced. These can typically be performed with a high-level scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure may be needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary for proper brake light and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does the cloning process work?
After you place your order, you will ship your original BCM to us. Our technicians use specialized equipment to read the unique data from your module and write it onto the replacement unit. We then ship the newly programmed module back to you, ready for installation.
Will I need to program this BCM at the dealership?
No. The entire purpose of our service is to pre-program the module for you. This saves you the time, cost, and hassle of a trip to the dealer for programming.
What are the most common signs of a failing BCM?
Common symptoms include erratic behavior of lights, power windows, and door locks; false security system alarms; warning lights on the dashboard; and in some cases, a vehicle that will not start.
How long does the service take?
Once we receive your original BCM, the programming and handling process typically takes 2-3 business days before we ship the replacement unit back to you. You will receive an email with tracking information once it’s on its way.
What happens if the airbag light comes on after installation?
In some vehicles, the new BCM needs to be electronically introduced to the airbag system. This is done via a “Setup SDM Primary Key in BCM” procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
Is there a core charge for this part?
No, there is no core charge. We require your original module to perform the data transfer service, but there are no additional fees or deposits involved.
