Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used BCM from a junkyard without proper programming. The result is almost always the same: more problems.

Frequently Asked Questions
Do I need to have the dealership program this BCM?
No. This module comes fully pre-programmed to your vehicle’s VIN. It is designed for a plug-and-play installation, so you can avoid the time and expense of a dealership visit.
What if my airbag light is still on after installation?
In some cases, particularly if DTC B1001 was present, an additional procedure called ‘Setup SDM Primary Key in BCM’ may be required. This is a simple sync procedure that can be performed with a capable professional scan tool and does not require full module programming.
Is this a difficult part to install myself?
The physical installation is very simple for most DIYers. The BCM is typically located under the driver’s side dash or steering column and is held in by a few clips or bolts. The entire swap can often be done in under 5 minutes.
