• 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 release button.

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 air-craft.

Electronic key battery depletion

• The standard battery life is 1 to 2 years. (The card key battery life is from one year to one year and a half.)
• If the battery becomes low, an alarm will sound in the cabin when the hybrid sys-tem is stopped.
• Battery-saving mode can reduce the power consumption of electronic keys that are not used for long periods of time.
• As the electronic key 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 necessary.
  • The smart access system with push-button 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.

You can replace the battery by yourself  However, as there is a danger that the electronic key may be damaged, it is recommended that replacement be carried out by your Lexus dealer.

To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of the following electrical 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

Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask your Lexus dealer for details.

If “A New Key has been Registered Contact Your Dealer for Details” is shown on the multi-information display

This message will be displayed each time the driver’s door is opened when the doors are unlocked from the outside for approxi-mately 10 days after a new electronic key has been registered.
If this message is displayed but you have not had a new electronic key registered, ask your Lexus dealer to check if an unknown electronic key (other than those in your possession) has been registered.

NOTICE
To prevent key damage

• Do not drop the keys, subject them to strong shocks or bend them.
• Do not expose the keys to high temperatures for long periods of time.
• Do not get the keys wet or wash them in an ultrasonic washer etc.
• Do not attach metallic or magnetic materials to the keys or place the keys close to such materials.
• Do not disassemble the keys.
• Do not attach a sticker or anything else to the surface of the electronic key.
• Do not place the keys near objects that produce magnetic fields, such as TVs, audio systems and induction cookers.
• Do not place the keys near medical electrical equipment such as low-frequency therapy equipment or micro-wave therapy equipment, and do not receive medical attention with the keys on your person.

Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or more away from electric appliances that are turned on. Radio waves emitted from electric appliances within 3.9 in. (10 cm) of the electronic key may interfere with the key, causing the key to not func-tion properly.

NOTICE
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 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 terminals. (To remove the battery cover, lightly grasp and pull it.) If the battery is corroded, have your Lexus dealer 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 battery. 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.
