Are you dealing with a cascade of bizarre electrical issues in your Chevrolet Impala or Monte Carlo?

Frequently Asked Questions
Do I need to do any programming after I receive this BCM?
No. We program the module to the VIN you provide before shipping. It is designed to be a plug-and-play installation. However, in some cases, minor relearn procedures, such as for the airbag or brake pedal position sensor, may be required after installation as noted in the listing.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN to the notes section during checkout or send it to us in a message after placing your order. We cannot ship the module until we have your VIN to program it.
Is this compatible with my vehicle?
This module is a direct replacement for 2000-2004 Chevrolet Impala and Monte Carlo models. It is compatible with multiple original service numbers, including 10350647, 10340320, 10438145, and others listed. Please verify your original part number or vehicle fitment to ensure compatibility.
What if the airbag light comes on after installation?
This is a known possibility. If the airbag warning light is on, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems. This is a quick procedure for any qualified automotive shop.
Why is a pre-programmed module a better choice?
A pre-programmed 2000-2004 Impala Monte Carlo BCM saves you significant time, money, and hassle. Without it, you would need to have your vehicle towed to a dealership for expensive, specialized programming after installing a blank module.
