An Expert’s Note on VIN Programming
As a technician, I’ve seen many DIYers buy a used computer from a salvage yard, only to find their vehicle still won’t start. That’s because modern GM vehicles have a sophisticated anti-theft system that locks the ECM to the original vehicle’s VIN. Our VIN programming service is not just a convenience—it’s essential. We pre-synchronize the module to your vehicle’s identity, allowing it to communicate correctly and start the engine. This is the secret to avoiding a tow to the dealership and getting the job done right in your own driveway.
