2021 Subaru Forester Smart Key Remote Fob Programming Instructions

Important Notice: The 2021 Subaru Forester does not allow onboard programming for smart key remote fobs. Programming must be completed by a trained technician using specialized diagnostic equipment.

Step-by-Step Programming Instructions:

  • Step 1: Schedule an appointment with a certified automotive technician or authorized service provider who is equipped with the proper tools to program Subaru smart key systems.
  • Step 2: If your vehicle is drivable, consider taking it directly to the technician’s location. This option is often more cost-effective than requesting mobile service.
  • Step 3: Bring all smart key remotes with you, including those that are already in use. Many systems require all remotes to be present during the programming session to retain their functionality.
  • Step 4: Be prepared to show valid proof of ownership—such as a vehicle registration card or title—especially if no functioning remotes are currently available.
  • Step 5: The technician will connect a diagnostic scan tool to the vehicle’s onboard system to begin the key programming process.
  • Step 6: Using manufacturer-approved software, the technician will register the new smart key to your vehicle’s electronic control modules.
  • Step 7: Once programming is complete, the technician will test the new remote to ensure all functions—such as locking, unlocking, keyless entry, and push-button start—are working correctly.
  • Step 8: Verify that any previously programmed remotes are still functional. If not, they may need to be reprogrammed during the same session.
  • Step 9: If you do not already have a spare remote, consider having an extra one programmed now to avoid inconvenience in the future.
