OTHER BENEFITS AND ASSISTANCE
training, equipment, quality and cus-
tomer satisfaction. These repair cen-
ters use Genuine Lexus Parts exclu-
sively in the repair of Lexus vehicles.
The Smart Key
Your Lexus vehicle was made with
two “Smart Keys” and an aluminum
key-number plate. Each Smart Key
includes an electronic main key that
has an integrated mechanical back-up
key. The electronic key controls the
remote-entry and theft-deterrent sys-
tems, enables the push-button start
switch and controls the engine immo-
bilizer. The mechanical key can be
removed from the electronic key and
used to operate the driver’s door lock,
the glove box lock and the trunk lock
(if equipped).
Replacing the Key
Your Lexus dealer can generate
replacement keys. Certain bonded/
registered locksmiths may also be
able to generate replacement keys.
When ordering a new key, bring all
keys for the vehicle to your dealer-
ship. If a Smart Key or the key-num-
ber plate is not available, a Lexus
dealer or certain locksmiths can
obtain the key code from a restricted-
access database. These businesses
can also access a service utility to
register the keys to the vehicle if all
registered keys have been lost.
If you lock your key in your vehicle
and do not have a spare, your dealer
can make a new mechanical key from
the code on the key-number plate.
Certain bonded/registered lock-
smiths may also be able to generate
a replacement mechanical key. If a
Lexus dealer is not available, please
refer to www.aloa.orgto find a bond-
ed/registered locksmith who per-
forms high-security key service.
Keeping the Key Safe
Replacing a Smart Key may be costly.
We advise you to keep a spare Smart
Key and the key-number plate in a
safe place. If you record the key num-
ber in more than one place, do not
record it in a way that can be easily
identified and associated with the
vehicle. For example, don’t leave the
number somewhere that can be
accessed by a valet. It is wise to keep
a copy of the key number outside of
the vehicle.
