push the release button and take
the key out.
The mechanical key can only be
inserted in one direction, as the

lock cylinder, turn it over and re-
attempt to insert it.
After using the mechanical key, store it in the electronic key. Carry the
mechanical key together with the electronic key. If the electronic key bat-
tery is depleted or the entry function does not operate properly, you will
need the mechanical key. (P. 585)

Operation of each component
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 427)
On vehicles without the smart key system, provide the attendant with the
valet key.
On vehicles with the smart key system, remove the mechanical key for your
own use and provide the attendant with the electronic key only.
■ If you lose your keys
New genuine keys can be made by your Toyota dealer using a master key
(vehicles without a smart key system) or the other key (vehicles with a smart
key system) and the key number stam ped 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 buttons 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.
