Using the mechanical key (vehicles with a smart key system)
To take out the mechanical key,
push the release button and take
the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be inserted
in a 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 battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key. (P. 781)

■When required to leave the vehicle ’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 589)
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.
■ Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a key (without a smart key system) or mechanical key (with a
smart key system) is lost, a new key can be made by your Toyota dealer
using the key number plate. ( P. 780)
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
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 a\
ircraft.
