This ensures every feature works exactly as it did from the factory, saving you the typical $150-$300 programming fee and hassle of a dealership appointment. This is the smartest, most efficient way to get your truck fixed right.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, wipers, security system, and HVAC blower controls. When it fails, these systems can become erratic or stop working altogether.
Is this module truly plug-and-play?
Yes. Because we program the module to your vehicle’s VIN before shipping, it arrives ready for installation. In most cases, you simply disconnect the battery, swap the old module with the new one, and reconnect the battery. No dealer programming is necessary for the BCM itself to function.
What if my airbag light is on after installation?
If the airbag light appears, it means the new BCM needs to be synchronized with the airbag system’s computer (SDM). This is a simple security procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a technician with a professional-grade scan tool. It is only required if the light is on.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep or dispose of your original module, making the replacement process as convenient as possible.
