Lost your key fob or need to program a new one for your 2004 Toyota Sienna? Don’t worry, programming your key fob can often be done right at home without a trip to the dealership. This guide provides you with simple, step-by-step instructions to program your 2004 Toyota Sienna key fob quickly and easily.
Before you begin, ensure you have your new, unprogrammed key fob and your 2004 Toyota Sienna vehicle. Follow these instructions carefully to synchronize your remote to your vehicle’s system.
Programming Steps:
- Start with the Basics: Make sure your key is out of the ignition.
- Driver’s Side Door Protocol: Open and unlock only the driver’s side door. Ensure all other doors, including the trunk and any sliding doors, are completely closed.
- Ignition Key Insertion (Twice): Within 5 seconds of step 2, insert your key into the ignition switch and then immediately pull it out. Repeat this insert and pull out action a second time.
- Door Cycling (Twice): Close, and then open the driver’s side door two times in a row.
- Ignition Key Insertion (Again): Insert the key into the ignition switch one more time, and then remove it.
- Repeat Door Cycling (Twice Again): Again, close and then open the driver’s side door two times consecutively.
- Ignition Key Insertion (Final): Insert the key into the ignition switch and this time, leave it in the ignition.
- Close Driver’s Door: Close the driver’s side door.
- Ignition ON then OFF: Turn the ignition switch to the “ON” position, and then immediately turn it back to the “OFF” position.
- Remove Key: Take the key out of the ignition.
- Lock Cycle Confirmation: At this point, the door locks should automatically cycle (lock then unlock). This lock cycling indicates that your 2004 Toyota Sienna has successfully entered programming mode and is ready to learn the new key fob.
- Remote Synchronization: Take your first key fob remote that you wish to program. Press and hold both the “LOCK” and “UNLOCK” buttons simultaneously for about 1.5 seconds. After releasing these two buttons, immediately press and hold only the “LOCK” button for 2 seconds.
- Programming Confirmation: The door locks should cycle once more to confirm successful programming of this remote. If you have additional key fobs to program, repeat step 12 with each additional remote. If you are finished programming all your remotes, proceed to the next step.
- Complete Programming: Open the driver’s side door. This action signifies the end of the programming sequence.
Your 2004 Toyota Sienna Key Fob Programming should now be complete. Test your key fob to ensure the lock and unlock buttons are working correctly.
