Precautions for handling the card key
Do not apply excess force when inserting the mechanical key into the card
key. Doing so may damage the card key.
If the battery or card key terminals get wet, the battery may corrode and
the card key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the
key, immediately remove the battery cover and wipe the battery and ter-
minals. (To remove the battery cover, lightly grasp and pull it.) If the bat-
tery is corroded, have any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional replace the battery.
Do not crush the battery cover or use a screwdriver to remove the battery
cover. Forcibly removing the battery cover may bend or damage the key.
If the battery cover is frequently removed, the battery cover may become
loose.
When installing the battery, make sure to check the direction of the bat-
tery.
Installing the battery in the wrong direction may cause the battery to
deplete rapidly.
The surface of the card key may be damaged, or its coating may peel off
in the following situations:
• The card key is carried together with hard objects, such as coins and
keys.
• The card key is scraped with a sharp object, such as the tip of a
mechanical pencil.

Conditions affecting operation
The smart entry & start system, push-button start system, wireless remote
control and immobilizer system use weak radio waves. In the following sit-
uations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system, push-button start sys-
tem, wireless remote control and immobilizer system from operating prop-
erly.
(Ways of coping: P. 630)
