Smart Key Remote Fob Programming Guide for the 2012 Toyota Highlander

Important Notice: The 2012 Toyota Highlander does not support onboard programming for smart key remote fobs. Professional programming with specialized diagnostic equipment is required.

Programming Options:

  • Step 1: Locate a Qualified Professional Identify a certified automotive professional who specializes in smart key programming. It is crucial they have experience with Toyota vehicles, particularly the 2012 Highlander.
  • Step 2: Confirm Professional Credentials Check the qualifications and experience of the professional to ensure they are capable of accurately programming your smart key remote fob.
  • Step 3: Schedule an Appointment Book a session with the selected professional. Consider whether it is more practical to visit their workshop or if they offer a mobile service, depending on your situation.
  • Step 4: Equipment Rental for Push Button Start If your Highlander is equipped with push-button start, explore the option to rent specialized programming equipment. This option is advisable only if you are technically proficient or can receive guidance from a professional during the programming.
  • Step 5: Attend the Programming Session During the appointment, the professional will use advanced diagnostic tools to program the smart key remote fob. Observe the process to ensure all necessary steps are completed. 
  • Step 6: Test the Newly Programmed Key After programming, test the smart key remote fob in the presence of the technician. Ensure that all functions, such as locking, unlocking, and panic alarm, are working correctly.
  • Step 7: Additional Key Considerations If you need to program more than one remote, ensure all are programmed during the same session to avoid any functionality issues with the vehicle’s security system.
  • Step 8: Confirm Full Functionality Ensure the vehicle recognizes the new key and that there are no errors or issues. Confirm that there are no warning lights on the dashboard and that the vehicle starts and operates normally.

Additional Guidelines:

  • Documentation and Proof of Ownership: Be prepared to provide proof of ownership, such as a registration or title document, especially if all original keys are lost.
