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 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.
  • If the battery becomes low, an alarm will sound in the cabin when the hybrid system is stopped.
  • 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 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.
  • 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.
