2007 TOYOTA AVALON engine

12
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 locks of the glove box and the
door located behind the rear seat arm-
rest. 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.
To protect items locked in the trunk or
glove box when using valet parking, leave
the sub key with the attendant.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.Do not bend the key grip.
Do not cover the key grip with any
material that cuts off electromagnet-
ic waves.
 Do not knock the key hard against
other objects.
 Do not leave the key exposed to
high temperatures for a long period,
such as on the dashboard and hood
under direct sunlight.
 Do not put the key in water or
wash it in an ultrasonic washer.
 Do not use the key with electromag-
netic materials.

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.The key consists of an electronic key
and a mechanical key. The mechanical
key is for emergency use. If the elec-
tronic key does not operate, you can
open the driver ’s door using the me-
chanical key.1. Electronic keys—These keys can lock or unlock all the doors and can open
the trunk by using the wireless remote
control function or entry function of the
smart key system.
2. Mechanical keys—These keys can lock or unlock the driver’s door, the glove
box and the door located behind the
rear seat armrest. Spare keys should not be left in the
cabin. In the event that a spare key is
left in the cabin, the smart key system
will remain actuated even after the
doors have been locked. Under these
circumstances, the trunk can be opened
even after the driver has exited and
locked the vehicle, increasing the dan-
ger of theft. (Refer to “OPENING
TRUNK WITH SMART KEY SYSTEM” on
page 45 in this Section.)
To protect items locked in the trunk or the
glove box when using valet parking, lock
the trunk opener switch and leave the
electronic key with the attendant. Keep the
mechanical key with you. For details about
locking the trunk opener switch, see
“—Luggage security system” on page 46
in this Section.
A transponder chip for engine immobilizer
system has been placed in the electronic
keys. These chips are needed to enable
the system to function correctly, so be
careful not to lose these keys.

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 Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.The engine immobilizer system is a
theft prevention system using an elec-
tronic code. The transponder chip in
the key has an electronic code and
transmits the code to the vehicle. Only
when the electronic code in the chip
corresponds to the register ID code for
the vehicle, the engine immobilizer sys-
tem will be canceled and the engine
will start.The engine immobilizer system is automat-
ically set when:
Vehicles with key cylinder
−type ignition
switch—The key is removed from the igni-
tion switch.
Vehicles with smart key system—The igni-
tion switch is turned off.
The indicator light will start flashing to
show that the system is set.

If any of the following indicator conditions
occur, contact your Toyota dealer.
The indicator light remains on.
The indicator light does not start flash-
ing under the following situations.
Vehicles with key cylinder−type ignition
switch—When the key is removed from
the ignition switch.
Vehicles with smart key system—When
the ignition switch is turned off.
The indicator light flashes inconsistent-
ly.
The engine immobilizer system is automat-
ically canceled when:
Vehicles with key cylinder −type ignition
switch—
You insert the key to the ignition switch.
Vehicles with smart key system—
You enter the vehicle carrying a key with
smart key system and press the “ENGINE
START STOP” switch (engine switch).
Even if the key battery is discharged, the
engine can be started. See “Smart key
system” on page 27 in this Section.
When the system is canceled, the indica-
tor 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 (vehicles with key cylin-
der −type ignition switch) or electronic key
(vehicles with smart key system). Howev-
er, there is a limit to the number of addi-
tional keys your Toyota dealer can make
for you.

Users of any electrical medical de-
vice other than implanted pacemak-
ers and implanted cardiac defibrilla-
tors should consult the manufactur-
er of the device for information
about its operation under the influ-
ence of radio waves. Radio waves
could have unexpected effects on
the operation of such medical de-
