2015 Toyota Prius Plug-In Smart Key Programming Instructions Keyless Entry Remote Fob

Step-by-Step Guide Important Notice: The 2015 Prius Plug-In is equipped with a push-button start Smart Key System that cannot be programmed using onboard procedures. Specialized diagnostic tools are required to register or replace remote fobs.

Programming Procedure:

  • Step 1: Park the vehicle on a level surface and ensure all doors are fully closed. Remove any other smart keys from the area to prevent interference with signal detection.
  • Step 2: Connect a Toyota-compatible scan tool or smart key programming interface to the vehicle’s OBD-II port, which is located underneath the dashboard on the driver’s side.
  • Step 3: Turn the vehicle to the ""ON"" position without starting the engine. Activate the programming device and select the Smart Key / Immobilizer System from the main menu.
  • Step 4: If you have a functioning key, hold it near the START/STOP button when prompted by the tool. The system will verify the key before proceeding with new key registration.
  • Step 5: Select the option to add or replace a smart key. Follow the prompts carefully as the system initiates communication with the car’s onboard ECU.
  • Step 6: Place the new smart key against the push-button start or into the backup slot as instructed. The vehicle will recognize the key and begin pairing.
  • Step 7: Wait for the scan tool to confirm that the registration is complete. Audible confirmation (such as a chime) or flashing hazard lights may indicate success.
  • Step 8: Turn off the vehicle, disconnect the programming tool, and allow the system to reset. This process typically takes less than one minute.
  • Step 9: Test all functions of the new smart key: Verify lock/unlock via remote buttons Confirm push-button start operates correctly Check that proximity features (e.g., touch unlock) are functioning

Additional Information:

  • The 2015 Prius Plug-In supports storage of up to five smart keys. If no working key is available, the system may require a reset or reinitialization, which could involve additional steps. Always store backup keys securely and away from the vehicle to prevent loss or theft. A low battery in the smart key can affect signal range and proximity entry functions. Replace the internal battery as needed.
