Do not put the electronic key in water or wash it in an
ultrasonic washer.

Do not keep the electronic key together with the
products emitting electromagnetic waves such as a
cellular phone.

Do not disassemble the electronic key.

Do not place the electronic key near electrical
appliances (e.g. television, computer or stereo) or
electrical medical equipment such as low frequency
medical appliances.

If gasoline, polishing agents or oil adheres to the
electronic key, it may deform or crack over time.
The electronic keys are required to deactivate the engine
immobilizer, and are essential for the engine immobilizer to
function correctly, so be careful not to lose these keys. If you
make your own duplicate key, you will not be able to cancel the
system or start the engine.
To protect items when using valet parking, turn the trunk lid
opener main switch to inoperative or lock the glove box if
necessary, and leave the electronic key (with the mechanical
key removed) with the attendant. For details, see “Trunk lid
opener main switch” on page 126.
If you should lose your electronic keys or if you need additional
electronic keys, duplicates can be made by a Lexus dealer
using the key number.
We recommend writing down the key number and storing it in
a safe place.
