2004 Toyota Tacoma Smart Key Remote Fob Programming Guide

Important Note: This procedure applies to vehicles equipped with a factory-installed keyless entry system. Timing is critical—each step must be completed within the listed time frames for the system to enter programming mode and accept the remote fob.

Programming Procedure

  • Step 1: Prepare the Vehicle Ensure the key is completely out of the ignition. Confirm the driver’s door is open and unlocked. All other doors must remain closed throughout the process.
  • Step 2: Begin the Initialization – Complete Within 5 Seconds A. Insert the key into the ignition (do not turn it), then remove it. B. Repeat: insert the key again (do not turn it), then remove it. These actions must be performed quickly and precisely.
  • Step 3: First Door Cycling – Complete Within 40 Seconds A. Close and then reopen the driver’s door. B. Repeat: close and reopen the driver’s door again. C. Insert the key into the ignition once more (do not turn it), then remove it.
  • Step 4: Final Setup Sequence – Complete Within 40 Seconds A. Close and reopen the driver’s door. B. Repeat: close and reopen the driver’s door again. C. Insert the key into the ignition and leave it inserted. D. Close the driver’s door. E. Turn the ignition switch to the ON position (do not start the engine), then return it to OFF. F. Remove the key from the ignition.
  • Step 5: Confirm Entry into Programming Mode Within 3 seconds of removing the key: The power door locks should automatically lock and then unlock once. This confirms the vehicle has entered programming mode. If the locks do not cycle, repeat the entire procedure starting from Step 1. Programming Remote Transmitters
  • Step 6: Program the Remote(s) – Complete Within 40 Seconds Per Remote A. Press and hold the LOCK and UNLOCK buttons on the remote simultaneously for approximately 1.5 seconds. B. Release both buttons, then immediately press and hold the LOCK button alone for 2 seconds. C. Watch for the door locks to lock and unlock once within 3 seconds. This confirms the remote was accepted. If the locks cycle twice, the remote was not accepted. Repeat Step 6 for that remote.
  • Step 7: Register Additional Remotes (if needed) Repeat Step 6 for each remote you wish to program. A total of up to four remotes can typically be registered to the system.
  • Step 8: Exit Programming Mode Open the driver’s door to finalize and exit programming mode. The system will return to normal operation.
  • Final Verification Step 9: Test All Remotes After closing all doors, test each programmed remote from outside the vehicle: Confirm lock and unlock functions. If applicable, verify additional functions such as panic alarm or tailgate release.
