INFORMATION
Be sure to take the smart key with you.
 In the following cases, the smart key system or
wireless remote control feature may not operate
properly. (If this happens, use a mechanical key to
lock or unlock the doors and trunk lid and a smart key
to start the engine.)
When facilities issuing strong electromagnetic
waves such as TV towers, electric power stations,
broadcasting stations are nearby.
When you are carrying a smart key together with a
mobile communications system such as a
twoway radio or cellular phone.
When the smart key is in contact with or covered
by a metallic object.
When another person is operating a wireless
remote control function on another vehicle near
your vehicle.
 If you do not drive your vehicle, store the smart key,
keeping it at least 5 m (15 ft.) away from the vehicle.
Alarms and warning messages
Your Lexus is equipped with alarms inside and outside, as
well as warning messages in the multiinformation
display, that remind you if there is a problem involving the
smart key system.
Cases which are expected to happen frequently are
shown in the illustrations and the other cases are
described in the table. If an alarm or warning message
comes on, check to see what the problem is referring to
the illustrations and table, and take the appropriate
measure.

KEYS AND DOORS
25
Locking the doors with smart key system
11L224
The smart key system will lock the doors without being
inserted into the door keyhole.
When you exit the vehicle carrying the smart key and push the
lock button on the outside door handle with all the doors
closed, all the doors will be locked provided that the electronic
code in the key corresponds to the registered ID code for the
vehicle.
At this time, you will hear one beep and the turn signal lights
flash once. However, when you push the lock button on the
outside door handle with any door not closed securely, a beep
sounds for 10 seconds. (For details, see page 27.)
If outer foot lights are illuminated, you can turn off the lights by
pushing the “LOCK” button on the smart key. (For details, see
“Outer foot lights” on page 233.)
INFORMATION
 When locking the doors, be sure to push the lock
button on the outside door handle slowly and surely.
If you push the button quickly, the doors may not
lock.
 When opening or closing a door, do not touch the
lock button on the outside door handle.
 When a wireless key is used to lock the doors and a
smart key is left in the ef fective range of the smart key
system in the vehicle, the doors cannot be unlocked
using the smart key system. In this case, use the
wireless remote function to unlock the doors.
 You cannot activate smart unlocking functions
within 3 seconds after the smart locking function is
activated.

KEYS AND DOORS
33
Battery power saving
When doors are locked, the smart key system transmits
electromagnetic waves to the outside of the vehicle at regular
intervals. For this reason, the vehicle battery will be
discharged if the vehicle is left for a long time. If the key is left
within the effective range of the smart key system outside of
the vehicle, the key and the vehicle transmit electromagnetic
waves periodically.
If these conditions continue for a long time, the battery in the
key and vehicle will be discharged and from the sixth day,
smart unlocking operations will become slow.
To prevent the batteries from being discharged, the smart key
system is automatically deactivated in the following conditions:
 If there is no smart door locking operation for more than 14
days
 If the key is left within the effective range of the smart key
system outside of the vehicle for more than 10 minutes
To reactivate the smart key system properly, perform any of the
following:
(a) Press the lock button on the outside door handle while
carrying the smart key.
(b) Perform a wireless remote control operation.
(c) Insert and turn the key in the keyhole of the door.INFORMATION
 To maintain communication with the vehicle, smart
keys (including master keys) use builtin battery
power. The battery service life is about 1 to 3 years
on average. If battery power becomes insufficient,
replace the battery with a new one.
 The smart key continually receives electromagnetic
waves, and if it receives strong electromagnetic
waves over a period of time, the battery can be
drastically run down. Therefore, avoid storing smart
keys near any electrical appliances.
Here is a list of electrical appliances which may have
adverse effects on the smart key performance: TVs,
personal computers, cellular phone or cordless
phone recharger units, electric light stands and
fluorescent desk lights
Note that you should always keep such electrical
appliances at least 1 m (3 ft.) away from the smart key.
