Smart Key Remote Fob Programming Guide for the 2021 Toyota Highlander

Important Notice: The 2021 Toyota Highlander is not equipped for onboard programming of smart key remote fobs. This task requires specialized diagnostic equipment and the expertise of a qualified professional.

Programming Steps:

  • Step 1: Locate a Qualified Professional Search for a certified professional who specializes in smart key programming for vehicles. It's important to select someone with specific experience with the latest Toyota Highlander models to ensure compatibility and precision in programming.
  • Step 2: Verify Professional Credentials Ensure that the professional you choose is fully qualified with the necessary certifications and has access to the appropriate diagnostic tools for programming smart key systems.
  • Step 3: Schedule an Appointment Arrange a suitable time to have your smart key remote fob programmed. Discuss whether it's more practical for you to visit their location, which may be more cost-effective than a mobile service.
  • Step 4: Attend the Programming Session Go to the scheduled appointment where the professional will use specialized computer equipment to program the smart key remote fob to your Highlander. Stay present during the process to ensure that all procedures are properly executed.
  • Step 5: Test the Smart Key Functions After the programming is complete, test the smart key remote fob while still at the service location. Verify all functionalities—locking, unlocking, engine start, and panic alarm—are operating as expected.
  • Step 6: Program Additional Remotes If you need additional remotes programmed, it's advisable to handle all programming during the same session to ensure all fobs are correctly synchronized with your vehicle's security system.
  • Step 7: Final Verification Before leaving, confirm that there are no errors and that the vehicle recognizes the new smart key without any issues. Check for any warning indicators on the dashboard to ensure everything is in order.

Additional Guidelines:

  • Documentation and Proof of Ownership: Be prepared to provide proof of ownership, such as a vehicle registration or title. This is often required for security purposes, especially when programming new keys.
