2023 Toyota Mirai

Smart Key Remote Fob Programming Instructions for the 2023 Toyota Mirai

Important Notice: The 2023 Toyota Mirai does not support onboard programming for smart key remote fobs. Programming must be completed by a qualified technician using secure diagnostic tools and manufacturer-approved software.

Programming Procedure:

  • Step 1: Schedule an appointment with a certified automotive technician who is equipped with the proper tools and training to program smart key systems.
  • Step 2: Confirm that the technician is experienced with hydrogen fuel cell vehicles and understands the advanced smart key system used in the Mirai.
  • Step 3: If your vehicle is operable, consider driving it to the service facility to reduce service charges that may apply for mobile visits.
  • Step 4: Bring all current smart key remotes to the appointment. In many cases, all remotes must be reprogrammed together to retain full functionality.
  • Step 5: Upon arrival, the technician will connect a diagnostic tool to your vehicle’s onboard system via the OBD-II port.
  • Step 6: The new smart key fob will be registered with the vehicle’s electronic system using secure, manufacturer-specific programming software.
  • Step 7: If any lost or unused remotes are no longer needed, the technician may remove them from the system to maintain vehicle security.
  • Step 8: Once programming is complete, the technician will test all functions of the smart key—including locking, unlocking, push-button start, and other remote features.
  • Step 9: You may be advised on the maximum number of remotes supported by the system and whether additional fobs can be added in the future.
  • Step 10: After confirming full functionality, store spare remotes securely and retain documentation from the service for future reference.

Additional Recommendations:

  • If no working remote is available, be prepared to present proof of ownership (such as a registration or vehicle title). Test your remotes periodically and replace batteries as needed to ensure consistent performance. Keep a backup key fob in a secure location for emergencies or future programming needs.
