Smart Key Remote Fob Programming Instructions for the 2019 Toyota Mirai

Important Notice: The 2019 Toyota Mirai does not support onboard programming for smart key remote fobs. A certified technician must perform the programming using specialized diagnostic equipment.

Programming Procedure:

  • Step 1: Schedule an appointment with a qualified automotive technician who has access to the appropriate diagnostic tools required for smart key programming.
  • Step 2: Confirm the technician has experience working with advanced keyless entry systems, particularly for vehicles using hydrogen fuel cell technology like the Mirai.
  • Step 3: If your vehicle is operational, driving it to the technician’s facility may help reduce service costs compared to arranging for on-site assistance.
  • Step 4: Bring all existing smart key remotes to the appointment. Some systems require all remotes to be present for reprogramming to ensure continued functionality.
  • Step 5: Upon arrival, the technician will connect a diagnostic interface to your vehicle through the OBD-II port to access the programming functions.
  • Step 6: The new smart key will be programmed using secure, manufacturer-approved software, ensuring compatibility with the vehicle’s security system.
  • Step 7: Any previously lost or inactive remotes may be removed from the system to prevent unauthorized access.
  • Step 8: Once programming is complete, the technician will test the remote to verify full functionality, including locking, unlocking, and engine start.
  • Step 9: You may be informed about the number of remotes your vehicle supports and whether additional keys can be added in the future.
  • Step 10: After successful programming, store backup remotes in a safe location and retain documentation from the service appointment for future reference.

Additional Recommendations:

  • Be prepared to provide proof of ownership (such as vehicle registration or title) if no working remotes are available. Periodically test each remote and replace batteries as needed to ensure continued reliability. Keep at least one spare remote accessible to avoid lockouts.
