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 PCM from a junkyard. It almost never works. Modern vehicles like your HHR have a sophisticated anti-theft system (GM’s Passlock) that links the PCM to your specific key and Body Control Module. A non-programmed module will result in a no-start condition every time. Our service handles this critical step for you, flashing the unit with your VIN and the latest factory software. This ensures all systems communicate correctly, just as the manufacturer intended, giving you a seamless and successful repair.
Don’t let a faulty computer keep your reliable HHR off the road. By ordering our pre-programmed 2006 HHR 12589998 PCM, you are choosing a hassle-free path to restoring your vehicle’s dependability. We handle the complex programming so you can focus on the simple installation.
