If you should lose your keys or if you need additional keys, duplicates can be made by a Toyota dealer using the key number. We recommend writing down the key number and storing it in a safe place.

The engine will start only when the electronic code in the chip corresponds to the registered ID code for the vehicle. The system is automatically set when the key is removed from the ignition switch. The indicator light will start flashing to show the system is set.
