Smart Key Remote Fob Programming Instructions for the 2020 Toyota Mirai

Important Notice: The 2020 Toyota Mirai does not allow for onboard or manual programming of smart key remote fobs. All key programming must be performed by a qualified technician using advanced diagnostic tools.

Programming Procedure:

  • Step 1: Contact a certified automotive technician who is trained to program smart key systems using manufacturer-authorized diagnostic equipment.
  • Step 2: Confirm the technician has specific experience with hydrogen fuel cell vehicles and smart key technology compatible with the Mirai.
  • Step 3: If your vehicle is drivable, consider transporting it to the technician’s service location to minimize service costs typically associated with mobile visits.
  • Step 4: Bring all functioning remotes with you. Certain systems require all remotes to be present during the session to retain full access functionality.
  • Step 5: Upon arrival, the technician will access your vehicle’s onboard system via the OBD-II port using secure diagnostic software.
  • Step 6: The new smart key remote will be electronically registered with your vehicle’s security system during the programming session.
  • Step 7: If there are missing or previously used remotes that are no longer needed, they can be removed from the system to enhance security.
  • Step 8: After programming is complete, the technician will test all remote functions, including door locking/unlocking, push-button start, and trunk release.
  • Step 9: The technician may review with you how many remotes your vehicle can support and how to add more in the future, if necessary.
  • Step 10: Once programming has been confirmed, store extra remotes safely and keep a record of the programming for future use.

Additional Recommendations:

  • If no working remotes are available, you may need to present proof of ownership (such as a vehicle title or registration). Regularly test all key fobs to ensure proper function and replace batteries as needed. Keep a backup remote stored in a secure location in case of emergencies.
