An Expert’s Note on VIN Programming
Many people consider using a module from a salvage yard, but this often leads to more problems. Your vehicle’s factory anti-theft system (like GM’s Passlock) is directly linked to the VIN stored in the original PCM. Simply swapping a used unit will almost always result in a no-start condition. Our VIN programming service isn’t just a convenience—it’s essential. We ensure the module we send you is a perfect digital match for your vehicle, preventing security conflicts and saving you the headache and expense of dealer-level diagnostics.
