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 a 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.  
Conditions affecting operation (wireless remote control)  
The wireless remote control function may not operate normally in the follow-  
ing situations:  
When the wireless key battery is depleted  
Near a TV tower, electric power plant, gas station, radio station, large dis-  
play, airport or other facility that generates strong radio waves or electrical  
noise  
When carrying a portable radio, cellular phone or other wireless communi-  
cation devices

When the wireless key is in contact with, or is covered by a metallic object  
When other wireless keys (that emit radio waves) are being used nearby  
If window tint with a metallic content or metallic objects are attached to the  
rear window  
Key battery depletion  
If the wireless remote control function does not operate, the battery may be  
depleted. Replace the battery when necessary.

3-1. Key information  
Electronic key battery depletion (vehicles with a smart entry & start sys-  
tem)  
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. (P. 417)  
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. 367)  
• The smart entry & start 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 1 m  
(3 ft.) 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  
• Induction cookers  
Table lamps  
Replacing the battery

Confirmation of the registered key number (vehicles with a smart entry &  
start system)

any authorized Toyota dealer or repairer, or another duly qualified and  
equipped professional for details.

On some models, the key cylinder rotates freely to isolate inside mechanism.

Carrying the electronic key on your person (vehicles with a smart entry  
& start system)  
Carry the electronic key 10 cm (3.9 in.) or more away from electric appli-  
ances that are turned on. Radio waves emitted from electric appliances  
within 10 cm (3.9 in.) of the electronic key may interfere with the key, caus-  
ing the key to not function properly.  
In case of a smart entry & start system malfunction or other key-related  
problems (vehicles with a smart entry & start system)  
Take your vehicle with all the electronic keys provided with your vehicle to  
any authorized Toyota dealer or repairer, or another duly qualified and  
equipped professional.  
When an electronic key is lost (vehicles with a smart entry & start sys-  
tem)  
If the electronic key remains lost, the risk of vehicle theft increases signifi-  
cantly. Visit any authorized Toyota dealer or repairer, or another duly quali-  
fied and equipped professional immediately with all remaining electronic  
keys that were provided with your vehicle.
