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.

YOUR WARRANTY RIGHTS   
AND OBLIGATIONS
The California Air Resources Board (CARB) 
and Toyota are pleased to explain the 
emission control system warranty for your 
2021 vehicle. In California, new motor   
vehicles must be designed, built and   
equipped to meet the state’s stringent   
anti-smog standards. CARB regulations 
require that Toyota must warrant the   
emission control system on your vehicle   
for the time periods indicated on the next 
page, provided there has been no abuse, 
neglect or improper maintenance of   
your vehicle.
Your emission control system may include 
parts such as the fuel injection system, 
ignition system, catalytic converter and   
engine computer. Also included may be   
hoses, belts, connectors and other   
emissions-related assemblies.
Where a warrantable condition exists,   
Toyota will repair your vehicle at no cost   
to you, including diagnosis, parts and labor.

MAINTENANCE
You are responsible for performance of  
the required maintenance indicated in the   
Owner ’s Manual  and this booklet. Toyota   
will not deny a warranty claim solely   
because you do not have records to show   
that you maintained your vehicle. However, 
any failure or noncompliance caused  
by lack of maintenance is not covered by   
this warranty.
When maintenance and repairs are   
paid for by you, these services may be 
performed by you or by any automotive 
service provider you choose. Toyota   
will not deny a warranty claim solely 
because you used a service provider   
other than a Toyota dealership for 
maintenance and repairs.  However,  
any failure or noncompliance caused by   
improper maintenance or repairs is not 
covered by this warranty.
