Programming Your 2004 Sienna Key Fob: A Step-by-Step Guide
Follow these instructions carefully to successfully program your 2004 Toyota Sienna key fob. Make sure to read each step thoroughly before proceeding.
Before You Begin
Ensure these conditions are met before starting the programming sequence:
- The ignition key is removed from the ignition.
- The driver’s side door is open, and all other doors are closed.
- The driver’s side door is unlocked. The lock status of other doors does not matter.
Programming Steps
Once you’ve confirmed the above conditions, proceed with the following steps within the specified time limits:
- Insert and Remove Key: Insert your key into the ignition switch, and then immediately pull it out. Do not turn the key on.
- Lock/Unlock Cycle (First Set): Within 40 seconds of step 1, use the power door lock switch on the driver’s door panel. Perform five lock/unlock cycles, starting with the “lock” action. A cycle is one press of the “lock” button followed immediately by one press of the “unlock” button. Maintain a consistent and relatively fast pace.
- Door Cycle: Close and then open the driver’s side door.
- Lock/Unlock Cycle (Second Set): Within 40 seconds of step 3, repeat the five lock/unlock cycles using the power door lock switch, again starting with “lock,” just as you did in step 2.
- Ignition Cycle:
- Turn the ignition key to the “ON” position (just before starting the engine) and then back to the “OFF” position.
- Repeat this “ON” to “OFF” ignition cycle one more time.
- Remove the key from the ignition.
- Programming Mode Confirmation: Within 3 seconds of removing the key, the power door locks should automatically cycle once (lock then unlock). This indicates that your Sienna has successfully entered programming mode. If the locks do not cycle, return to step 1 and repeat the entire process.
- Transmitter Programming: Within 40 seconds of entering programming mode:
- Press and hold both the “lock” and “unlock” buttons on the key fob remote simultaneously for 1 second.
- Immediately after releasing both buttons, press and hold only the “lock” button for 2 seconds.
- Within 3 seconds, the door locks should cycle once (lock then unlock) to confirm successful programming of that remote. If the door locks do not cycle, or cycle twice, repeat steps 7a and 7b for that remote.
- Important: Repeat steps 7a and 7b for every remote you want to program, including any previously working remotes and your new remote(s). You must program all remotes in this session before proceeding to the next step.
- Final Step: Close the driver’s door.
Important Tips for Successful Programming
- Program All Remotes Together: As highlighted in step 7c, you must program all of your key fobs (new and old) in one programming session. If you only program the new ones, your old remotes will no longer work.
- Timing is Key: Pay close attention to the time limits mentioned in each step, particularly the 40-second windows. Work quickly and smoothly through the lock/unlock cycles and ignition turns.
- Test After Completion: Do not test your remotes until you have fully completed all steps, including closing the driver’s door in step 8. Prematurely pressing buttons on the remote can interrupt the programming process.
By following these instructions, you should be able to easily program your 2004 Toyota Sienna key fob and regain full keyless entry functionality. Enjoy the convenience of your newly programmed remote!
