LX570_OM_OM60L21U_(U) Using the mechanical key
Take out the mechanical key. 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 look
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 battery is depleted or the smart
access system with push-button
start does not operate properly,
you will need the mechanical key.

Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start, wire-
less remote control and engine immobilizer system from operating properly.
(Ways of coping: P. 8 6 7 )●
When the electronic key battery is depleted ●
Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise●
When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices ●
When the electronic key is in contact wi th, or is covered by the following metal-
lic object
• Card 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 or using 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
• Personal computers or person al digital assistants (PDAs)
• Digital audio players

Battery-saving function
In the following circumstances, the entry func tion is disabled in order to prevent the
vehicle and electronic key batteries from discharging. ●
When the entry function has not been used for 2 weeks or more ●
When the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when... ●
The vehicle is locked using th e door handle lock switch.●
The vehicle is locked/unlocked using the wireless remote control function
( P. 48) or the mechanical key. ( P. 8 6 7 )■
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 becomes low, an alarm will sound in the cabin when the engine
stops. ( P. 4 3 )●
The battery becomes depleted even if the electronic key is not used because
the key always receives radio waves. If the smart access system with push-but-
ton start or the wireless remote control function does not operate, or the detec-
tion area becomes smaller, the battery may be depleted. Replace the battery
when necessary. ( P. 7 8 0 )●
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
