3-1. Key information

If you lose your keys
New genuine keys can be made by your Toyota dealer using the other key
(vehicles without a smart key system) or the other mechanical key (vehicles
with a smart key system) and the key number stamped on your key number
plate. Keep the plate in a safe place such as your wallet, not in the vehicle. 

■

When riding in an aircraft
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any button on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.
