Ready to tackle the programming yourself? Here’s a detailed guide for programming your 2004 Toyota Sienna key fob:
Before you begin:
- Gather your materials: You’ll need all your Toyota Sienna key fobs (both the working one and the one you want to program)
- Ensure your vehicle is in a safe and quiet location.

Programming Instructions:

- Confirm Programming Mode: After the fifth cycle, leave the key in the ignition in the “OFF” position. The doors should lock and unlock automatically, confirming that you have successfully entered programming mode.
- Program New Key Fob: Within 40 seconds, press and hold the “LOCK” button on your new key fob for at least one second, then release. This step tells the vehicle to recognize and store the new fob’s signal.
- Repeat for Additional Fobs: If you have more than one key fob to program, repeat step three for each additional fob. Remember, you only have 40 seconds after entering programming mode to program all desired fobs.
- Exit Programming Mode: Once you have finished programming all your key fobs, turn the ignition to the “ON” position and then back to the “OFF” position. The doors should lock and unlock again, indicating that you have successfully exited programming mode.
Troubleshooting Tips:
- Programming Not Working? Double-check that you are following each step correctly and within the time limits. Sometimes, even a slight deviation can disrupt the process.
