GM ECU VIN Programming Service (Chevy, GMC, Cadillac & Buick)

Our GM ECU VIN Programming Service provides accurate VIN writing in Chevrolet, GMC, Cadillac, and Buick ECU/PCM modules. Important: This service updates the VIN only and does not make the vehicle start. Your car must already have a functional ECU/PCM and powertrain to run.

How GM ECU VIN Programming Works

  1. Order Online: Purchase this service and check your receipt for the mail-in shipping address.
  2. Ship Your ECU/PCM: Send your module securely using packaging that protects the electronics.
  3. VIN Programming: Our certified technicians write the VIN exactly as provided, ensuring the ECU/PCM records the correct VIN for registration, compliance, and system recognition.
  4. Return Shipment: Your module is returned ready to install.

Important Details

  • This service writes VIN only in the ECU/PCM; it does not include cloning, key programming, or immobilizer functions.
  • The vehicle must start and run independently; VIN programming does not enable starting.
  • VIN write is permanent and does not affect mileage or vehicle performance.
