Those used modules are programmed for a different vehicle with different options—power locks, security systems, engine types.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. The main benefit of our service is that we program the Body Control Module to your vehicle’s specific VIN before we ship it to you. This means it arrives ready to be installed, saving you the time and expense of a dealership visit.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as the programming is a required step.
What if my airbag light turns on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a standard relearn process for many technicians.
Is this a simple plug-and-play installation?
For most functions, yes. After the physical installation, some vehicles may require additional relearn procedures, such as a Brake Pedal Position Relearn, which can be done with a capable diagnostic tool. These procedures are straightforward for any qualified mechanic.
My original part number isn’t 20839063, will this still work?
Yes, this module is a direct replacement for all the part numbers listed in the description, such as 15921352, 25892622, 22860591, and many others. As long as your original part number is on our compatibility list, this module will function correctly once programmed to your VIN.
