1-1. Key information
IS250C/350C_U
●The card key is not waterproof.
■When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circumstances
demand. (→P. 5 1 , 3 5 7 )
Remove the mechanical key for your own use and provide the attendant with the
electronic key only.
■Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the event that
a mechanical key is lost, a new key can be made at your Lexus dealer using the key
number plate. ( →P. 5 2 7 )
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any
buttons on the electronic key while inside the aircraft cabin. If you are carrying an
electronic key in your bag etc, ensure that the buttons are not likely to be pressed
accidentally. Pressing a button may cause the electronic key to emit radio waves
that could interfere with the operation of the aircraft.
●If the battery cover is not installed and
the battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive termi-
nal facing the Lexus emblem.

■To operate the system properly
●Make sure to carry the electronic key when operating the system. Actions such
as locking and unlocking the doors cannot be performed from outside the vehi-
cle if the electronic key is inside the vehicle, even when the retractable hardtop
is open.
●Do not get the electronic key too close to the vehicle when operating the sys-
tem from the outside of the vehicle.
●Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention may not function.)
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the
rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in
the glove box when the engine is started or “ENGINE START STOP” switch
modes are changed.
●Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside the vehicle, it may be possible to start the
engine if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
●Gripping the door handle when wearing a glove may not unlock the door.
