2004 Toyota 4Runner Keyless Entry Remote Fob Programming Instructions

For Vehicles with Factory Keyless Entry System

Important Note: This procedure allows you to program one or more remote fobs. Accurate timing is essential—complete each step within the specified time window to ensure successful programming.

Step-by-Step Programming Procedure:

  • Step 1: Preparation Ensure the key is removed from the ignition. The driver’s door must be open and unlocked. All other doors should be closed.
  • Step 2: Initial Key Cycle (within 5 seconds)
  • A) Insert the key into the ignition without turning it, then remove it.
  • B) Insert the key again (do not turn), then remove it.
  • Step 3: Driver Door Cycle (within 40 seconds)
  • A) Close the driver’s door, then reopen it.
  • B) Close the door again, then reopen it a second time.
  • C) Insert the key into the ignition (do not turn), then remove it.
  • Step 4: Final Setup (within 40 seconds)
  • A) Close and reopen the driver’s door.
  • B) Repeat: close and reopen the driver’s door.
  • 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 back to OFF.
  • F) Remove the key from the ignition.
  • Step 5: Enter Programming Mode Within 3 seconds, the power door locks should lock and then unlock, confirming the system is in programming mode. If the locks do not cycle, restart from Step 1.
  • Step 6: Program Remote(s) (within 40 seconds)
  • A) On the remote, press and hold both the LOCK and UNLOCK buttons simultaneously for 1.5 seconds.
  • B) Immediately after releasing both buttons, press and hold the LOCK button alone for 2 seconds. If the door locks lock and then unlock 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 finalize the programming session. Test all remotes to confirm proper operation.
