For more complicated reprogramming, it may be needed to use a diagnostic tool, especially for more recent automobiles. This is often done by an automotive technician. The steps usually include:
- Connecting the diagnostic tool to the vehicle's OBD-II port.
- Selecting the choice for key programming.
- Following on-screen instructions to input new key details into the vehicle's ECU.
