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 can-

not 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 mechan-

ical 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. (

P. 692)

■

Panic mode

■

When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (

P. 534)

Remove the mechanical key for your own use and provide the attendant with the elec-

tronic key only.

■

If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using another

mechanical key and the key number stamped on your key number plate. Keep the plate

in a safe place such as your wallet, not in the vehicle.

■

When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-

tons 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.

Using the mechanical key

When

is pressed for longer than about

one second, an alarm will sound intermittently

and the vehicle lights will flash to deter any per-

son from trying to break into or damage your

vehicle.
To stop the alarm, press any button on the elec-

tronic key.

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. (

P. 630)

●

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 elec-

tronic key battery may be depleted. Replace the battery when necessary. (

P. 630)

• 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 peri-

ods of time, set the electronic key to the battery-saving mode. (

P. 160)

●

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

■

Replacing the battery
P. 630

■

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

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-fre-

quency 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.

■

In case of a smart access system with push-button start malfunction or other key-

related problems
Take your vehicle with all the electronic keys provided with your vehicle to your Lexus

dealer.

■

When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit

your Lexus dealer immediately with all remaining electronic keys that were provided

with your vehicle.
