Smart Key Remote Fob Programming Instructions for the 2018 Toyota Mirai

Important Notice: The 2018 Toyota Mirai does not support onboard programming for smart key remote fobs. Programming must be performed by a qualified automotive technician using advanced diagnostic tools.

Programming Procedure:

  • Step 1: Schedule a visit with a certified technician who has the proper diagnostic equipment and training to program smart key systems specific to this model.
  • Step 2: Confirm the technician is experienced in working with proximity-based smart keys and understands the advanced technology used in hydrogen-powered vehicles like the Mirai.
  • Step 3: If the vehicle is drivable, consider transporting it to the technician’s service facility, which may reduce overall service fees compared to mobile service.
  • Step 4: Bring all currently functioning remotes to the appointment. Some vehicle systems require all smart keys to be present during programming to ensure they remain active.
  • Step 5: At the service location, the technician will connect a diagnostic interface to the vehicle’s OBD-II port to initiate the programming process.
  • Step 6: The new smart key remote will be securely programmed into the vehicle’s electronic system using authorized software.
  • Step 7: If any old or lost remotes are no longer in use, they may be removed from the system during programming to protect against unauthorized access.
  • Step 8: After programming, the technician will test all remotes to confirm that core functions such as locking, unlocking, and push-button start are working properly.
  • Step 9: The technician may also inform you of the maximum number of remotes the system supports and offer guidance on adding additional fobs in the future.
  • Step 10: Once functionality is confirmed, store any spare remotes securely and retain documentation of the programming service for future reference.

Additional Recommendations:

  • If no valid remotes are available, be prepared to show proof of vehicle ownership (such as a registration or title). Test your remote fobs regularly and replace batteries when needed to maintain reliability. Keep a backup key stored safely to avoid potential lockout situations.
