Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your Chevrolet, GMC, or Cadillac? Issues like flickering lights, malfunctioning power windows, a haywire security system, or even a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and seemingly unrelated problems. Replacing it at a dealership often means expensive parts, labor, and programming fees. Our mail-in programming service for the GM BCM 13587704 offers a direct, cost-effective, and hassle-free solution.
The Simple, No-Hassle Programming Process
Forget about towing your vehicle to the dealer and waiting for complex programming. Our service is designed for simplicity and convenience. Here’s how it works:
- Place Your Order: Complete your purchase through our secure checkout.
- We Contact You: Our team will reach out with detailed instructions on how to safely remove and ship your original BCM to our facility.
- Data Cloning: Once we receive your original module, our expert technicians will perform a full data transfer. We clone all critical information—including your vehicle’s VIN, mileage, security data, and specific options—to a replacement BCM.
- Shipped Back to You: We promptly ship your original module and the newly programmed replacement module back to you. The replacement is now 100% plug-and-play, ready for installation.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra 1500 in the shop with a textbook case of BCM failure. The owner reported that the dome lights would stay on, the driver’s side window wouldn’t roll down, and the key fob only worked intermittently. After confirming the BCM was the culprit, we explained the options. A new module plus dealership programming was quoted at over $800. Instead, we used our cloning service. We transferred the data from his faulty unit to a replacement GM BCM 13587704. The installation took less than 30 minutes, and every single issue was resolved instantly. The customer saved hundreds of dollars and avoided a lengthy dealership visit.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty Body Control Module is a likely cause. This service is designed to correct these problems by providing a fully functional, programmed replacement.
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Malfunctioning security system, including random alarm activation or key fob recognition failure.
- ✔ Instrument cluster warning lights (like the airbag or security light) illuminating without cause.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up due to immobilizer communication loss.
- ✔ Radio or infotainment system turning on or off by itself.
Post-Installation Procedures
Our cloning service makes the installation as simple as possible. However, due to the complexity of modern vehicle systems, some models may require minor post-installation steps. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ may be needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some vehicles, a brake pedal position sensor recalibration might be required to ensure proper brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we transfer the complete software and vehicle-specific data (like VIN, keys, and mileage) from your original BCM to a replacement unit. This makes the replacement module plug-and-play, avoiding the need for expensive dealership programming.
Why is this better than buying a new BCM from the dealer?
This service is significantly more affordable and convenient. You avoid the high cost of a new module and the separate programming fees charged by dealerships. Plus, you can perform the physical installation yourself, saving on labor costs.
Is this part truly plug-and-play?
Yes, in over 99% of cases. Because we clone your vehicle’s exact data, the replacement BCM is recognized by your vehicle’s other computers as the original. In rare instances, a simple relearn procedure as noted above may be required.
How long does the cloning process take?
We pride ourselves on a fast turnaround. The cloning service is typically completed within 1-2 business days of us receiving your original module.
Will my original keys and remote fobs work?
Absolutely. Since we transfer all the security information from your old BCM, your existing keys and remotes will work immediately with the new module, with no reprogramming needed.
What if my original BCM is completely dead or unreadable?
In many cases, even if the BCM is non-functional in the vehicle, we can still extract the necessary data directly from the board. Please contact us before ordering if you suspect your module is severely damaged (e.g., by water or fire).
