Your vehicle is supplied with two kinds
of key.
1. Master key—This key works in every
lock.
2. Sub key—This key will not work in the
glove box.
To protect things locked in the glove box
when you have your vehicle parked, leave
the sub key with the attendant.
Since the doors can be locked without a
key, you should always carry a spare
master key in case you accidentally lock
your keys inside the vehicle.KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
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 you to write down the key
number and keep it in safe place.Your vehicle is supplied with the two
kinds of key.
1. Master key (black)—This key works in
every lock. Your Toyota dealer will
need it to make you a new key with
built−in transponder chip.
2. Sub key (gray)—This key will not work
in the glove box.
A transponder chip for engine immobiliser
system has been filled in the head of the
master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.

To protect things locked in the glove box
when you have your vehicle parked, leave
the sub key with the attendant.
Since the side door can be locked without
a key, you should always carry a spare
master key in case you accidentally lock
your keys inside the vehicle.
NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:
When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.
When starting the engine, do not
use the key with other transponder
keys around (including keys of oth-
er vehicles) and do not press other
key plates against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts. If
this happens, remove the key once
and then insert it again after taking
off other transponder keys (includ-
ing keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
engine.
