Keys

Key types

The following keys are provided with the vehicle.

1. Electronic keys
   • Operating the smart access system with push-button start
   • Operating the wireless remote control function
2. Mechanical keys
3. Key number plate
4. Card key (electronic key) (if equipped)
   Operating the smart access system with push-button start

■Card key (if equipped)

• 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 the battery cover is not installed and the battery falls out or if the battery was removed because the key got wet, reinstall the battery with the positive terminal facing the Lexus emblem.

• The card key is not waterproof.

■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.

■Electronic key battery depletion

• The standard battery life is 1 to 2 years.

  (The card key battery life is about a year and a half.)

• If the battery becomes low, an alarm will sound in the cabin when the hybrid system stops.
• 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.
• 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
  • Induction cookers
  • Table lamps

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

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, or medical electrical equipment, such as low-frequency therapy equipment.

■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 function properly.

■Handling 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 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.
  • The card key is scraped with a sharp object, such as the tip of a mechanical pencil.
  • The surface of the card key is wiped with thinner or benzene.

To stop the alarm, press any button on the electronic key.

■Back door reserve lock function (vehicles with power back door) This function is a function which reserves locking of all doors, beforehand, when the back door is open. When the follow is done, all the doors except the back door are locked and then back door will also be locked at the same time it is closed.

2. Push the wireless lock button during the automatic closing operation of the back door.

Using the mechanical key

To take out the mechanical key, push the release button and take the key out.

The mechanical key can only be inserted in one direction, as the key only has grooves on one side. If the key cannot be inserted in a lock cylinder, turn it over and re-attempt to insert it.

After using the mechanical key, store it in the electronic key. Carry the mechanical key together with the electronic key. If the electronic key battery is depleted or the entry function does not operate properly, you will need the mechanical key.

■When required to leave the vehicle's key with a parking attendant Lock the glove box as circumstances demand. Remove the mechanical key for your own use and provide the attendant with the electronic key only.

■If a wrong key is used The key cylinder rotates freely to isolate inside mechanism.

■Card key

• To store the mechanical key in the card key, insert it while pressing the release button.

NOTICE
