3-1. Key information  
Using the mechanical key  
To take out the mechanical key,  
push the release button and take  
the key out.  
The mechanical key can only be  
inserted in one direction, as the  
key only has grooves on one side.  
If the key cannot be inserted in a  
lock cylinder, turn it over and re-  
attempt to insert it.  
After using the mechanical key, store it in the electronic key. Carry the  
mechanical key together with the electronic key. If the electronic key bat-  
tery is depleted or the entry function does not operate properly, you will  
need the mechanical key. (P. 512)

Panic mode  
When  
is pressed for longer than  
about one second, an alarm will sound  
intermittently and the vehicle lights will  
flash to deter any person from trying to  
break into or damage your vehicle.  
To stop the alarm, press any button on the  
electronic key.  
When required to leave the vehicle’s key with a parking attendant  
Lock the glove box as circumstances demand. (P. 364)  
Remove the mechanical key for your own use and provide the attendant with  
the electronic key only.  
If you lose your mechanical keys  
New genuine mechanical keys can be made by your Toyota dealer using the  
other mechanical key and the key number stamped on your key number  
plate. Keep the plate in a safe place such as your wallet, not in the vehicle.  
When riding in an aircraft  
When bringing a key with wireless remote control function onto an aircraft,  
make sure you do not press any buttons on the key while inside the aircraft  
cabin. If you are carrying the key in your bag etc., ensure that the buttons are  
not likely to be pressed accidentally. Pressing a button may cause the key to  
emit radio waves that could interfere with the operation of the aircraft.

3-1. Key information  
Key battery depletion  
The standard battery life is 1 to 2 years.  
If the battery becomes low, an alarm will sound in the cabin when the engine  
stops.  
As the electronic key always receives radio waves, the battery will become  
depleted even if the electronic key is not used. The following symptoms indi-  
cate that the electronic key battery may be depleted. Replace the battery  
when necessary. (P. 447)  
• The smart key system or the wireless remote control does not operate.  
• The detection area becomes smaller.  
• The LED indicator on the key surface does not turn on.  
To avoid serious deterioration, do not leave the electronic key within 3 ft. (1  
m) of the following electrical appliances that produce a magnetic field:  
• TVs  
• Personal computers  
• Cellular phones, cordless phones and battery chargers  
• Recharging cellular phones or cordless phones  
Table lamps  
• Induction cookers  
Precautions when disconnecting the battery  
In some cases, it may not be possible to unlock the doors using the smart  
key system immediately after the battery has been disconnected. Use the  
wireless remote control or the mechanical key to lock or unlock the doors.  
The engine may not start on the first attempt after reconnecting the battery  
but will start normally after the second attempt. This is not a malfunction.  
The engine switch mode is memorized by the vehicle. When the battery is  
reconnected, the system will return to the mode it was in before the battery  
was disconnected. Before disconnecting the battery, turn the engine switch  
off.  
If you are unsure what mode the engine switch was in when the battery was  
disconnected, be especially careful when reconnecting the battery.  
Replacing the battery  
P. 447  
Confirmation of the registered key number  
The number of keys already registered to the vehicle can be confirmed. Ask  
your Toyota dealer for details.  
If a wrong key is used  
The key cylinder rotates freely to isolate inside mechanism.

Carrying the electronic key on your person  
Carry the electronic key 3.9 in. (10 cm) or more away from electric appli-  
ances that are turned on. Radio waves emitted from electric appliances  
within 3.9 in. (10 cm) of the electronic key may interfere with the key, caus-  
ing the key to not function properly.  
In case of a smart key system malfunction or other key-related prob-  
lems  
Take your vehicle with all the electronic keys provided with your vehicle to  
your Toyota dealer.  
When an electronic key is lost  
If the electronic key remains lost, the risk of vehicle theft increases signifi-  
cantly. Visit your Toyota dealer immediately with all remaining electronic  
keys that was provided with your vehicle.
