How to Program a 2008 Toyota Sienna Ignition Transponder Chip Key
Step by Step How to Programming Instructions:
1. Close all doors.
2. Insert your Master Key (Black) into the ignition 5 times and leave it in the ignition on the 5th time.
3. Open and close the driver's door 6 times within 20 seconds.
4. Remove the Master Key.
5. Insert the new blank key and turn to the ON position.
6. Leave in ON position for a full minute while the key registers with the vehicle. Look at the red engine immobilizer light (the red light to the left of the speedometer which is car shaped with a black key in the middle of it.) It is blinking...wait about 1 minute and it will turn off by itself.
7. After the engine immobilizer light turns off, remove the new key and insert original Master key and start engine.
8. Now test new key.
