LEXUS RC F (2019 year). Instruction - part 9

3-1. Key information

RC F_U

■

Card key (if equipped)

●

The card key is not waterproof.

●

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 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.

■

When required to leave the vehicle’s key with a parking attendant
Set the luggage security system (

P. 152) on and lock the glove box (P. 351) as cir-

cumstances demand. 

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. 

●

To store the mechanical key in the card key,

insert it while pressing the lock release button.

●

If the battery cover is not installed and the bat-

tery falls out or if the battery was removed

because the key got wet, reinstall the battery

with the positive terminal facing the Lexus

emblem.

■

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 engine is stopped.

(

P. 485)

●

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. 427)

• 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

• Table  lamps

• Induction cookers

■

Replacing the battery
P. 427

■

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 wrong key is used
The key cylinder rotates freely, isolated from the internal mechanism.

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.

■

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, including the

card key, 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 and the card key that

were provided with your vehicle.

■

Handling the card key (if equipped)

●

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.

If the key is dropped into water, or if drinking water etc. is spilled on the key, immedi-

ately 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 follow-

ing 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.

WARNING

Observe the following precautions.

Failure to do so may result in death or serious injury.

■

Before driving

●

Make sure that the trunk lid is fully closed. If the trunk lid is not fully closed, it may

open unexpectedly while driving and hit near-by objects or luggage in the trunk may

be thrown out, causing an accident.

●

Do not allow children to play in the trunk.

If a child is accidentally locked in the trunk, they could suffer from heat exhaustion,

suffocation or other injuries.

●

Do not allow a child to open or close the trunk lid.

Doing so may cause the trunk lid to open unexpectedly, or cause the child’s hands,

head, or neck to be caught by the closing trunk lid.

■

Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a collision, they are

susceptible to death or serious injury.

WARNING

■

Using the trunk
Observe the following precautions.

Failure to do so may cause parts of the body to be caught, resulting in serious injury.

●

Remove any heavy loads, such as snow and ice, from the trunk lid before opening it.

Failure to do so may cause the trunk lid to suddenly shut again after it is opened.

●

When opening or closing the trunk lid, thoroughly check to make sure the surround-

ing area is safe. 

●

If anyone is in the vicinity, make sure they are safe and let them know that the trunk is

about to open or close.

●

Use caution when opening or closing the trunk lid in windy weather as it may move

abruptly in strong wind.

●

On an incline it is more difficult to open or close the trunk lid than on a level surface,

so beware of the trunk lid unexpectedly opening or closing by itself. Make sure that

the trunk lid is fully open and secure before using the trunk.

●

Do not attach any accessories other than genuine Lexus parts to the trunk lid. Such

additional weight on the trunk lid may cause the lid to suddenly shut again after it is

opened. 

●

When opening the trunk lid, take care so that

it does not hit anyone in the face or any other

part of the body.

●

When closing the trunk lid, take extra care to

prevent your fingers etc. from being caught.

●

When closing the trunk lid, make sure to

press it lightly on its outer surface. If the trunk

handle is used to fully close the trunk lid, it

may result in hands or arms being caught.
