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.

The engine immobilizer system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The engine will start only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.The system is automatically set when the
key is removed from the ignition switch.
On some models—
The indicator light will start flashing to
show the system is set.
If any of the following indicator conditions
occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See “Theft deterrent
system” on page 48 in this Section.)
The indicator light does not start flash-
ing when the key is removed from the
ignition switch.
The indicator light flashes inconsistent-
ly.Inserting the registered key in the ignition
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
For your Toyota dealer to make you a
new key with built
−in transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the engine.
NOTICE
Do not modify, remove or disas-
semble the engine immobilizer sys-
tem. If any unauthorized changes or
modifications are made, proper opera-
tion of the system cannot be guaran-
teed.
