KEYS AND DOORS

KEYS
G11007
1Electronic keys These keys will work for the doors,
trunk and can start the engine. They will not work for
glove box and trunk storage extension door. Your
dealer will need one of them to make a new key.
Before you use these keys, be sure to read “Smart access
system with push− button start” on page 11.
2
Mechanical keys These keys work for the doors,
trunk, glove box and trunk storage extension door,
but cannot start the engine.
3Key number plate Keep the plate in a safe place
such as your wallet, not in the vehicle.
Using a mechanical key
G11008
When you use the mechanical key included on the side of the
electronic key, slide the lock knob in the arrow direction and
take out the key as shown. To put the key back, slide the key
gently until it locks, paying attention to the angle and position
of the key. Be sure to put the key back when not in use.

KEYS AND DOORS
10The 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 130.
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.
