THE NEW WORLD OF
ANTI-THEFT
TECHNOLOGY
This Scion vehicle may be equipped
with an electronic “immobilizer”
anti-theft system. When the key is
inserted into the ignition switch it
transmits an electronic code to an
immobilizer computer. The engine will
only start if the code in the key matches
the code in the immobilizer. If the code
does not match, the immobilizer
disables the ignition and fuel systems.
While an exact physical copy of the key
will open the door and allow retrieval of
items locked in the vehicle, it won’t
start the vehicle unless the key has the
same code as the immobilizer.
SECURITY
For security purposes, access to key
codes and service procedures for
electronically registering replacement
keys is restricted. Only an Authorized
Servicing Dealership* or certain
bonded/registered independent
locksmiths can generate replacement
keys.
* For the purposes of this system, an Authorized Servicing Dealership is a Scion dealership or a Toyota
dealership.

REPLACING THE KEY
Upon purchase, each vehicle should
have two master keys, one valet key
and an aluminum tag with a key-code
imprinted on it.
To generate a fully functional
replacement key (one that will both
open the doors and start the engine),
one of the master keys is required. To
make a key that will open the door for
retrieval of items locked inside the
vehicle, the valet key or aluminum
key-code tag can be used. If a master
key or the aluminum key-code tag is
not available, an Authorized Servicing
Dealership or certain registered
locksmiths can obtain the key code
from a restricted-access database.
These businesses can also access a
service utility to reprogram the
immobilizer if all registered master
keys have been lost. If an Authorized
Servicing Dealership is not available,
please refer towww.aloa.orgto find a
bonded/registered locksmith who
performs high security key service.
KEEPING THE KEY SAFE
Replacing an immobilizer key may be
costly. It is advisable to keep a spare
master key and the aluminum key-code
tag in a safe place. If you record the
key-code in more than one place, do
not record it in a way that can be easily
identified and associated with the
vehicle. For example, don’t leave the
code somewhere that can be accessed
by a valet. It is wise to keep a copy of
the key-code outside of the vehicle.
If the vehicle was delivered with less
than all three keys and the aluminum
key-code tag, consider having an
Authorized Servicing Dealership or a
qualified independent automotive
locksmith make a duplicate key before
you need it.
