Restore Flawless Performance to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2015 Sierra Denali 2500? Issues like flickering lights, unresponsive power windows and locks, a malfunctioning security system, or even a no-start condition can all point to a failing Body Control Module (BCM). Your premium vehicle was built for reliability, and this critical component is the nerve center for its body electronics. When it fails, it can bring your daily operations to a halt. This Programmed 2015 Sierra 2500 Body Control Module service is the definitive, hassle-free solution to restore your vehicle’s full functionality and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often causing confusion and costly diagnostic time. If you’re experiencing any of the following, our BCM cloning service is the targeted repair you need:
- Intermittent or non-working interior/exterior lights
- Power windows, door locks, or mirrors behaving erratically
- Instrument cluster warnings or inaccurate gauge readings
- Vehicle security system faults or alarm sounding unexpectedly
- Communication errors with other modules (DTCs like U0140)
- Engine will not crank or start due to immobilizer issues
Instead of purchasing an expensive new module from the dealer and paying for hours of programming, our service simplifies the entire process. We transfer all the critical data from your original BCMโincluding the VIN, mileage, immobilizer keys, and specific RPO codesโto a fully tested replacement unit. The result is a component that is truly ready for your vehicle.
Expert Insight: Why Cloning is a Superior Solution
On modern GM platforms like your Sierra, the BCM is not a simple swap-out part. It’s deeply integrated with the vehicle’s anti-theft and security systems. Simply installing a used BCM from another vehicle will result in a no-start condition due to a VIN and immobilizer data mismatch. Dealerships solve this by installing a brand-new, blank module and performing a series of complex programming procedures. Our cloning service bypasses this entirely. By perfectly replicating your original module’s data, we deliver a unit that the vehicle instantly recognizes as its own, preserving all original keys and settings without the need for additional programming fees.

Frequently Asked Questions
How does this BCM cloning service work?
It’s a simple process. After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract all the vehicle-specific data and flash it onto a fully vetted replacement BCM. We then ship the programmed module back to you, ready for installation.
Why can’t I just install a used BCM from another truck?
The BCM is tied to your vehicle’s specific VIN and anti-theft system. A used module from another vehicle will have mismatched data, preventing your engine from starting and causing numerous other electronic conflicts. Our cloning service is essential to prevent these issues.
Will I need to do any programming after I install it?
No, the core programming is complete. However, on some models, post-installation relearn procedures may be necessary. This can include an ‘Airbag System Sync’ if the airbag light is on, or a ‘Brake Pedal Position Relearn’. These procedures often require a professional-grade scan tool.
How do I know if this part number is correct for my vehicle?
This BCM, part number 13506935, is a direct replacement for several other part numbers including 13592137, 13506936, 13587704, and 13594764. Please check the part number on your original module or consult our detailed fitment list to confirm compatibility.
What is the turnaround time for the service?
Our goal is to program and ship your replacement BCM within 1-2 business days of receiving your original module. Return shipping time will depend on your location and the shipping method selected.
Do I need to send my keys with the module?
No, you do not need to send your keys. Our cloning process transfers all the necessary security information from your old BCM, so your existing keys will be recognized by the replacement module automatically.
