Engine immobilizer system

LS12044
The engine immobilizer system is a
theft prevention system. When you in-
sert the key in the engine 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.
Never leave the keys inside the vehicle
when you leave the vehicle.

The system is automatically set when the
key is removed from the engine switch.
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
D
when the theft deterrent system is set-
ting or activating. (See "Theft deterrent
system" on page 39 in this Section.)
The indicator light does not start flash-
D
ing when the key is removed from the
engine switch.
The indicator light flashes inconsistent-
D
ly.
Inserting the registered key in the engine
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
The system is maintenance−free.
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
semble the engine immobilizer sys-
tem. If any unauthorized changes or
modifications are made, proper opera-
tion of the system cannot be guaran-
teed.
