2021 TOYOTA SUPRA ECU

THE NEW WORLD OF
ANTI-THEFT TECHNOLOGY
This Toyota vehicle may be equipped
with an electronic “immobilizer” anti-theft
system. When the key is present inside the
vehicle, 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 a Toyota dealer
or certain bonded/registered independent
locksmiths can generate replacement keys.

REPLACING THE KEY
Upon purchase, each vehicle should have
two master keys.
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 aluminum key-code
tag can be used. If a master key or the
aluminum key-code tag is not available,
a Toyota dealer or certain registered
locksmiths can order a key from a
restricted-access system. Their
businesses can also disable master
keys that have been lost. If a Toyota
dealer is not available, please refer to
www.aloa.org to find a bonded/
registered locksmith who performs
high-security key service.


KEEPING THE KEY SAFE
Replacing lost keys may be costly. It is
advisable to keep a spare master key in a
safe place.
If the vehicle was delivered with less than
two keys, consider having a Toyota dealer
or a qualified independent automotive
locksmith make a duplicate key before
you need it.
