As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money on BCMs that weren’t programmed correctly. On these 2002-2007 GM platforms, the BCM is deeply integrated with other modules like the security system (Passlock/Passkey) and the airbag system (SDM).

Our VIN programming service ensures the module has the exact software and calibration your vehicle left the factory with, guaranteeing it communicates seamlessly with all other systems right out of the box. This is the secret to a successful, stress-free repair.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, power locks, interior and exterior lighting, wipers, the security system, and the heating and air conditioning (HVAC) system.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The BCM is usually located under the steering column or behind the center dash. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors to the new module. It can often be completed in under 30 minutes.
Will I need to do anything after installing this module?
Because the module is pre-programmed to your VIN, no further computer programming is required.
