7-2. Steps to take in an emergency  
If you lose your keys  
If the electronic key  
does not operate prop-  
erly (vehicles with a  
smart key system)  
New genuine keys can be  
made by your Toyota dealer  
using the other key (vehi-  
cles without a smart key  
system) or mechanical key  
(vehicles with a smart key  
system) and the key number  
stamped on your key num-  
ber plate.  
If communication between  
the electronic key and vehi-  
cle is interrupted (P.121)  
or the electronic key cannot  
be used because the battery  
is depleted, the smart key  
system and wireless remote  
control cannot be used. In  
such cases, the doors can  
be opened and the engine  
can be started by following  
the procedure below.  
Keep the plate in a safe  
place such as your wallet,  
not in the vehicle.
