2008 Toyota 4Runner Keyless Entry Remote Fob Programming Instructions

For Vehicles Equipped with Factory Keyless Entry System

Important: This process allows you to program one or more remote fobs. Precision and timing are essential—each step must be completed within the time limits provided to successfully enter and complete programming mode.

Step-by-Step Procedure:

  • Step 1: Initial Setup Ensure the key is out of the ignition. The driver’s door must be open and unlocked. All other doors must remain closed.
  • Step 2: Key Insertion Sequence (within 5 seconds)
  • A) Insert the key into the ignition without turning it, then remove it.
  • B) Repeat: Insert the key again (do not turn), then remove it.
  • Step 3: Door Cycle Sequence (within 40 seconds)
  • A) Close the driver’s door, then open it.
  • B) Close and open the driver’s door again.
  • C) Insert the key into the ignition (do not turn), then remove it.
  • Step 4: Final Setup Sequence (within 40 seconds)
  • A) Close the driver’s door, then open it.
  • B) Close and open the door once more.
  • C) Insert the key into the ignition and leave it inserted.
  • D) Close the driver’s door.
  • E) Turn the ignition to the ON position (do not start the engine), then turn it back to OFF.
  • F) Remove the key from the ignition.
  • Step 5: Confirm Programming Mode Within 3 seconds, the door locks should automatically lock and then unlock, confirming entry into programming mode. If the locks do not cycle, restart the procedure from Step 1.
  • Step 6: Program Remote(s) (within 40 seconds)
  • A) Press and hold the LOCK and UNLOCK buttons on the remote simultaneously for 1.5 seconds.
  • B) Immediately after releasing both buttons, press and hold the LOCK button alone for 2 seconds. If the locks cycle once, the remote was successfully programmed. If the locks cycle twice, the remote was not accepted—repeat Step 6A and 6B.
  • C) Repeat this process for each additional remote.
  • Step 7: Exit Programming Mode Open the driver’s door to end the programming session. Test each remote to confirm proper functionality.
