An Expert’s Note on Installation
“Many people are tempted to buy a used computer from a salvage yard, not realizing it’s a critical mistake. GM vehicles use a Vehicle Anti-Theft System (VATS/Passlock) that links the PCM to your specific key and VIN. A used, un-programmed module will prevent your engine from starting, period. By ordering a pre-programmed 2006 Trailblazer PCM, you bypass this entire headache. We handle the complex part, so all you need to do is a simple 30-minute ‘security relearn’ procedure with your own key, which requires no tools. It’s the smartest way to ensure your repair is successful on the first try.”
Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. We program the computer with your vehicle’s VIN before we ship it. This means it is ready for installation when you receive it. You will only need to perform a simple security relearn procedure, which can be done yourself without any special tools.
What is the security relearn procedure?
The security relearn procedure syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. We include simple, step-by-step instructions with your order.
Where do I provide my vehicle’s VIN?
You can enter your VIN in the designated field during the checkout process. If you forget, you can also reply to your order confirmation email with the VIN. We cannot ship your part until we receive this information.
How do I know this is the correct part for my Trailblazer?
This module is a direct replacement for the part numbers listed in the description and fits the 2006 Trailblazer with the 4.2L engine, among other compatible GM models. Providing your VIN guarantees we will program and send the exact correct module for your vehicle’s configuration.
