2021 TOYOTA 4RUNNER ignition

7Introduction
INTRODUCTION
THE IMMOBILIZER KEY
THE NEW WORLD OF
ANTI-THEFT TECHNOLOGY
This Toyota 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 a Toyota dealer
or certain bonded/registered independent
locksmiths can generate replacement keys.
