Operation of each component
LS460/LS460L_GE (OM50G06E)
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, pre-
venting the smart entry & start system, wireless remote control and engine immobi-
lizer system from operating properly. (Ways of coping: P. 631)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key together with the following devices that emit
radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves

■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery is low, an alarm will sound in the cabin when the engine is started or
stopped. ( P. 158)
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart entry & start system or the wireless
remote control does not operate, or the detection area becomes smaller, the bat-
tery may be depleted. Replace the battery when necessary. ( P. 575)
●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
• Table lamps
• Induction cookers
