1998 Toyota Avalon Keyless Entry Remote Fob Programming Guide

Important Notice: This procedure allows you to program remote transmitters without specialized tools. Follow all steps carefully and within the required time frames. Up to four remotes can typically be programmed.

Programming Procedure:

  • Step 1: Prepare the Vehicle Ensure the key is out of the ignition. Open the driver's door and leave it open. Make sure all other doors are closed. Confirm the driver’s door is unlocked.
  • Step 2: Insert and Remove the Key Insert the key into the ignition (do not turn it), then immediately remove it.
  • Step 3: Perform the First Lock/Unlock Cycle (Within 40 Seconds) Using the driver’s door power lock switch, perform five lock/unlock cycles, starting with lock. (One cycle = lock, then unlock. Use a steady rhythm of about one cycle per second.) After the five cycles, close the driver’s door, then reopen it.
  • Step 4: Perform the Second Lock/Unlock Cycle (Within 40 Seconds) Again, using the driver’s door power lock switch, perform five lock/unlock cycles, starting with lock. Insert the key into the ignition. Turn the ignition to the ON position (do not start the engine), then turn it back to OFF. Repeat: Turn the ignition to ON, then back to OFF again. Remove the key from the ignition.
  • Step 5: Confirm Entry Into Programming Mode Within 3 seconds, the door locks should automatically cycle once (lock, then unlock), indicating the vehicle has entered programming mode. If the locks do not cycle, repeat the process from Step 1.
  • Step 6: Program the Remote(s) (Within 40 Seconds) For each remote: A. Press and hold the lock and unlock buttons simultaneously on the remote for 1 second, then release. B. Immediately press and hold the lock button alone for 2 seconds, then release. C. The door locks should cycle once, confirming the remote was accepted. If the locks cycle twice, the remote was not accepted—repeat steps A and B.
  • Step 7: Finalize the Process Repeat Step 6 for each additional remote. Once all remotes are programmed, close the driver’s door to exit programming mode.

Additional Notes:

  • Perform all steps promptly and in sequence—timing is critical. A maximum of four remotes may be programmed. If unsuccessful, restart the procedure from the beginning and ensure the timing is accurate.
