KEYS AND DOORS
Locking/Unlocking the doors
When you push the "LOCK" button on the key briefly, all
the doors can be locked from outside the vehicle.
When they are locked securely, the emergency flashers will
flash and one beep will sound.* However, when you push the
"LOCK" button with any door not closed securely, the buzzer
sounds for 10 seconds.** To stop the buzzer, close all the
doors securely or push the "UNLOCK" button. If the key is in
the ignition switch, locking cannot be done.
Make sure all the doors are locked when you leave the vehicle.
Push the "LOCK" button once again. If they were already
locked, the turn signal lights will flash.***
NOTE: *The emergency flashers can be set not to flash and
beep volume can be changed. **The buzzer can be set not
to sound if a door is not closed securely. ***The turn signal
lights can be set not to flash. Ask your Lexus dealer for
details.
NOTICE
Do not push the "LOCK" button any longer than 2 to 3
seconds. Pushing the button longer activates an alarm.

When you push the "UNLOCK" button, the driver's door
is unlocked. Pushing that button once again within 3
seconds from the first push, the passenger's door is also
unlocked.*
NOTE: *The 2-step unlocking function can be changed.
Ask your Lexus dealer for details.
At this time, the emergency flashers will flash twice and two
beeps will sound.* Together with the activation of unlocking,
the interior light comes on for 15 seconds if the interior light
switch is in "DOOR" position.** However, this function does
not work when the ignition switch is in the "ACC" or "ON"
position. For further information, see "Interior lights" on page
65.
You have 30 seconds to open a door after using the wireless
remote unlock feature.*** If a door is not opened by then, all
the doors will be automatically locked again.
Even if the "LOCK" or "UNLOCK" button is kept pressed in, the
locking or unlocking operation is not repeated. Release the
button and then push again.
NOTE: *The emergency flashers can be set not to flash and
beep volume can be changed. **The interior light can be set
not to come on or the duration of lighting can be changed.
***The time before automatic re-locking can be changed.
Ask your Lexus dealer for details.
