🔹 Step-by-Step Guide

✅ Subaru Key Fob Programming Instructions (2000–2006):

  1. Sit in the car and close all doors.

  2. Insert key into ignition and turn to the “ON” position (do not start).

  3. Within 10 seconds, open and close the driver’s door 3 times.

  4. Remove the key from the ignition.

  5. On the remote, press LOCK, then UNLOCK, then LOCK.

    • The door locks should cycle to confirm programming.

  6. Repeat for each additional remote (up to 4 total).

  7. Reinsert key and turn to ON to exit programming mode.

  8. Test all remotes.

🔹 Alternate Method (Used on Some Models):

  1. Open the driver’s door.

  2. Insert key, turn ignition to ON, then OFF — repeat 10 times within 15 seconds (ending in ON).

  3. Locks should cycle to confirm programming mode.

  4. Press any button on the remote.

  5. Locks cycle to confirm pairing.

  6. Turn key to OFF and test the remote.

🔹 Notes

  • All remotes must be programmed during the same session.

  • This procedure does not program ignition chips, only remote buttons.

  • Lock cycling is the key indicator that you’re in the correct mode.

🔹 Troubleshooting

  • No lock cycling? Repeat faster or check for door open/close mistakes.

  • Still no success? Some Canadian-market or higher trims require scan tools.

  • Try a new remote battery or alternate remote.
