End Electrical Gremlins and Restore Your Truck’s Performance
Are bizarre electrical issues turning your powerful 2015 GMC Sierra Denali 2500 into a source of frustration? When your truck’s lights, windows, security system, or other accessories start acting erratically, a failing Body Control Module (BCM) is the most common culprit. Get back in control with our professionally programmed BCM solution, designed to restore your vehicle’s full functionality without the time and expense of a dealership visit.
This listing is for a replacement BCM that is programmed using the data from your original module. This cloning service is essential for a true plug-and-play installation. After your purchase, we will contact you with simple instructions to ship your original BCM to our facility. Our expert technicians will then transfer all vehicle-specific data to the replacement unit and ship it back to you, ready to install.
Common Symptoms of a Failing BCM & Your Solution
If you’re experiencing any of the following, a faulty BCM is likely to blame:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights (headlights, taillights, dome lights) staying on or not turning on.
- Erratic behavior from the alarm or security system.
- The vehicle fails to start, even with a good battery and starter.
- False warning lights appearing on your instrument cluster.
Our Programmed 2015 Sierra Denali 2500 BCM is the definitive solution, providing a fully functional module coded specifically to your truck’s VIN and factory options.

Expert Technician Insight: As a diagnostician with over 20 years on the floor, I’ve seen countless hours wasted chasing electrical problems. The BCM is the central command for your truck’s body electronics. Our cloning service is the most reliable repair because it transfers the exact, vehicle-specific configurationโincluding your key data and factory-installed optionsโfrom your old unit to the new one. This ensures seamless integration that a brand new, un-programmed module from the parts counter simply can’t offer without specialized dealer tools.
Important Post-Installation Procedures
While our programming makes the installation straightforward, some GM vehicles may require one of the following procedures to finalize the sync between modules. These can be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, the ‘Setup SDM Primary Key in BCM’ procedure will be needed to sync the system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary to ensure proper brake light function and traction control system performance.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How exactly does the cloning service work?
It’s a simple mail-in process. After you place your order, we will email you a prepaid shipping label and instructions. You securely package your original BCM and send it to us. Once we receive it, we transfer the data to the replacement unit and ship it back to you, typically within 1-2 business days.
Will I need to program this BCM after I receive it?
No. The entire point of our service is to handle the programming for you. The module you receive will be ready to install in your vehicle without any need for additional programming or dealer intervention.
What if my original BCM is completely dead or water damaged?
In many cases, we can still recover the necessary data even from non-communicating or damaged modules. If you suspect your BCM is severely damaged, please contact us before ordering to discuss the situation. We have advanced data recovery options available.
Will my existing keys work with the replacement BCM?
Yes. Because we clone your original module, all the security information, including your key data, is transferred over. Your existing keys will work exactly as they did before, with no need for reprogramming.
Is this a difficult part to install myself?
The physical installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the steering column. The main challenge is the programming, which our service completely eliminates. Be aware that some vehicles may require the post-installation relearn procedures mentioned above.
