Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing a cascade of frustrating electrical problems in your Cadillac XTS, ATS, or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a security system that won’t cooperate, or even a vehicle that refuses to start can often be traced back to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can create chaos. This listing offers a straightforward, cost-effective solution to get your vehicle back in perfect working order without the exorbitant costs and hassle of dealership programming.
We provide a replacement BCM that is professionally programmed using the data from your original unit. This cloning service ensures a seamless, plug-and-play installation. You simply send us your faulty BCM, and our technicians will transfer all the critical vehicle-specific information—including VIN, mileage, and key data—to a fully functional replacement module. We then ship the ready-to-install unit back to you, eliminating the need for any complex on-car programming with expensive scan tools.
We recently had a customer with a 2013 Cadillac XTS whose dashboard lit up like a Christmas tree. The power locks were acting on their own, the radio would randomly shut off, and the dealer quoted them over $1200 for a new BCM plus several hours of labor for programming. They were frustrated and looking for a better option. They sent us their original BCM, we performed our cloning service, and shipped the replacement back the next day. They installed it in under an hour, and every single issue was resolved. They saved hundreds of dollars and avoided a lengthy dealership visit.

Post-Installation Information
Our cloning service makes the installation process as simple as possible. However, in some vehicles, minor recalibrations may be needed to sync related systems. These are not full programming procedures but simple relearns that may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light is on.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on certain models.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and communication between other electronic modules.
Why is cloning my original BCM the best option?
Cloning transfers your vehicle’s unique VIN and security data to the replacement module. This makes the new part plug-and-play, avoiding the need for expensive and complicated programming at a dealership, which is required for new or used modules.
How long does this entire process take?
We typically program and ship your replacement BCM within 24-48 hours of receiving your original module. The total time depends on shipping transit times to and from our facility.
Do I need to do any programming myself?
No. The module you receive from us is fully programmed and ready for installation. In rare cases, a simple relearn procedure like the Airbag System Sync or Brake Pedal Position Relearn might be needed, as detailed above.
Is there a core charge for this part?
No, there is no core charge. We use your original module solely for the data transfer process. You are not required to send it back after receiving your programmed replacement.
