An Expert’s Note on VIN Programming
Many owners are tempted to source a used computer from a salvage yard, hoping for a cheap fix. However, for a vehicle like the 2006 H3, this almost never works. The factory Vehicle Theft Deterrent (VTD) system, also known as Passlock, is tied directly to the original PCM’s programming. Installing a non-programmed module will result in a no-start security lockout. Our service completely bypasses this issue. We program the module to your specific VIN before it ships, so it integrates seamlessly with your existing keys and security system upon installation.
Don’t let a faulty module compromise your vehicle’s legendary capability. This is the most reliable and straightforward way to restore the electronic heart of your truck. Installing this professionally programmed 2006 Hummer H3 engine computer is the key to putting performance issues in your rearview mirror.
