Restore Flawless Control to Your GM Truck or SUV
Is your 2015 Sierra Denali 2500 suffering from frustrating and unpredictable electrical problems? One moment the power windows work, the next they don’t. The security light flashes for no reason, or worse, you’re faced with a vehicle that won’t start. These aren’t just minor annoyances; they are symptoms of a failing Body Control Module (BCM), the central nervous system for your vehicle’s electronics. Instead of facing a costly and complicated trip to the dealership, our professional programming service provides a simple, reliable, and direct solution to get your truck back to 100% functionality.
Common Symptoms of a Failing BCM & Your Direct Solution
A faulty BCM can wreak havoc on your vehicle’s systems, often leading to misdiagnosis and expensive, unnecessary repairs. If you’re experiencing any of the following, a failing BCM is the likely culprit:
- Power windows, door locks, or mirrors operating erratically or not at all.
- Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- Erratic instrument cluster behavior, with gauges dropping out or warning lights appearing randomly.
- Remote keyless entry failing to work consistently.
- Vehicle security system engaging without cause, preventing the engine from starting.
Our mail-in programming service for this programmed 2015 Sierra Denali 2500 BCM is the definitive fix. We take your original module’s dataโincluding the VIN, mileage, and specific options for your truckโand flash it directly onto this replacement unit. The result is a true plug-and-play module, ready for installation right out of the box, with no additional dealer programming required.

Expert Insight: Why Our Cloning Service is Superior
As a technician with over 20 years of experience, I’ve seen countless owners frustrated by BCM issues. The dealership solution involves installing a new, blank module that then requires multiple hours of programming with proprietary scan tools to learn the vehicle’s VIN, security keys, and specific RPO codes for its options. It’s a complex and costly process. Our cloning method bypasses this entirely. By performing a direct data transfer from your original unit, we create a perfect digital twin. When you install our programmed 2015 Sierra Denali 2500 BCM, the vehicle recognizes it as its own. This preserves all original functionality, from the memory seats to the specific lighting patterns, providing a solution that is not only simpler but fundamentally more reliable.
Guaranteed Fitment for Multiple GM Models
This BCM programming service is compatible with a wide range of 2015-2018 General Motors vehicles. Please verify that your original module carries one of the following part numbers: 13592137, 13506935, 13506936, 13587704, or 13594764. Models include various years/options for the Corvette, Impala, Sierra & Silverado (1500/2500/3500), Suburban, Tahoe, Yukon, Escalade, XTS, ATS, CTS, and Sonic.
Frequently Asked Questions
How does this mail-in programming service work?
It’s simple. After you complete your purchase, we will contact you with detailed instructions to ship your original BCM to our facility. Once we receive it, our technicians will read the data and program the replacement module. We then ship the plug-and-play replacement back to you with tracking information.
Is this a true plug-and-play installation?
Yes. Because we clone the data from your original BCM, the replacement module is ready for immediate installation upon arrival. In most cases, you will not need any special tools or procedures. It’s designed to be as simple as swapping the part.
What do I need to do after installing the new BCM?
While the module is plug-and-play, some vehicles may require a ‘Brake Pedal Position Relearn’ or an ‘Airbag System Sync’ if the airbag light appears. These are simple procedures that can be performed with a professional diagnostic tool. Please refer to the Post-Installation Procedures tab for more details.
How long does the entire process take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. The total turnaround time will depend on shipping speeds to and from our facility.
What if my original BCM is damaged or cannot be read?
In cases where the original module is severely damaged (e.g., by water or fire) and the data cannot be retrieved, cloning may not be possible. Please contact us before purchasing if you suspect your module is unreadable, and we can discuss alternative solutions.
Will this fix my specific electrical problems?
This programmed 2015 Sierra Denali 2500 BCM is the direct solution for issues originating from a faulty Body Control Module. It corrects the erratic behavior of lights, locks, windows, and other body electronics controlled by the BCM. If you are unsure, we recommend having a qualified technician diagnose the issue first.
