Card key (if equipped)
●
The card key is not waterproof.
●
The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card key does not operate properly. ●
If it is difficult to take out the mechanical
key, push down the lock release button
using a pen tip etc. If it is still difficult to
pull it out, use a coin etc. ●
To store the mechanical key in the card
key, insert it while pressing the lock

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 terminal

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 acci-
dentally. Pressing a button may cause the
electronic key to em it radio waves that
could interfere with the operation of the air-
craft.

Before driving ●
To reduce key battery depletion when the
electronic key is to not be used for long
periods of time, set the electronic key to
the battery-saving mode. ( → P.108)●
As the electronic ke y always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( → P.403)
• The smart access system with push-but-
ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
•The LED indicator on the key surface
does not turn on.●
To avoid serious deterioration, do not
leave the electronic ke y within 3 ft. (1 m)
of the following electr ical appliances that
produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and
battery chargers
• Recharging cellular phones or cordless
phones
• Table lamps
• Induction cookers ■
Replacing the battery
→ P.403■
Confirmation of the number of regis-
tered keys
The number of keys already registered to
the vehicle can be confirmed. Ask your
Lexus dealer for details.
