Your vehicle is supplied with two kinds
of keys.1. Master keys—These keys work in ev- ery lock.
2. Sub key—This key will not work in the glove box.
To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the front doors and sliding 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 writing down the key num-
ber and storing it in a safe place.Your vehicle is supplied with two kinds
of keys. 1. Master keys (black)—These keys work in every lock. Your Toyota dealer will
need one of them to make a new key
with a built −in transponder chip.
2. Sub key (gray)—This key will not work in the glove box.
A transponder chip for engine immobilizer
system has been placed 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.

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 remov-
ing 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.
