7-2. Steps to take in an emergency
When trouble arises
■ When the electronic key does not work
properly
● Make sure that the smart entry & start
system has not been deactivated using
the Remote Touch or at your Lexus
dealer. If it is off, turn the function on.
● Check if battery-saving mode is set. If it is
set, cancel the function. (P.143)
Use the mechanical key (P.129) in
order to perform the following opera-
tions:
On some models: An alarm will sound if
the alarm is set. (P.92)
■ Unlocking the door
1 Pull the driver’s door handle and
insert the mechanical key.
2 Unlock the door.
Some models: Turning the key rearward
unlocks the driver’s door. Turning the key
once again within 5 seconds unlocks the
other doors.
3 Remove the key, return the handle,
and then pull the handle again.
■ Locking the door
1 With the door open, push down the
inside lock button.
If the electronic key does not
operate properly
If communication between the
electronic key and vehicle is inter-
rupted (P.143) or the electronic
key cannot be used because the
battery is depleted, the smart entry
& start system and wireless remote
control cannot be used. In such
cases, the doors and trunk can be
opened and the engine can be
started by following the procedure
below.
■ In case of a smart entry & start system
malfunction or other key-related
problems
Take your vehicle with all the electronic
keys provided with your vehicle (includ-
ing the card key) to your Lexus dealer as
soon as possible.
