Our process completely bypasses this problem. By programming the module to your VIN, we ensure it’s a perfect electronic match for your truck right out of the box. This saves you from a tow bill and hundreds of dollars in dealer-only programming fees, turning a complex repair into a manageable DIY job.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power locks, interior and exterior lighting, the anti-theft system, and dashboard warning lights. When it fails, it can cause a wide range of strange electrical issues.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the specific software and settings for your truck’s exact features and options (like power seats, keyless entry, etc.). This step is essential for the module to function correctly and is the key to our ‘plug-and-play’ solution.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is very manageable. The BCM is typically located under the driver’s side or center of the dashboard. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. Since our module is pre-programmed, no special computer tools are needed for the initial installation.
What if my airbag light is on after I install it?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag light comes on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a mechanic with a professional-grade scan tool. This is a simple sync procedure that resolves the light.
Will this fix my flashing ‘Security’ light and no-start problem?
Yes, a failing BCM is one of the most common causes of a persistent security light and the resulting no-start condition in these GM vehicles. This programmed 1999-2000 Sierra 2500 Body Control Module is the correct solution for that specific problem.
My original part number isn’t on your list. Will this still work?
Our list includes the most common part numbers, but there may be others. As long as your vehicle’s year, make, and model are included in our fitment list, this module will be the correct replacement. The VIN-programming process ensures it works regardless of the original part number.
