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 backup
key. The electronic key controls the
remote-entry and theft-deterrent
systems, enables the push-button
start switch and controls the engine
immobilizer. 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 dealership.
If a Smart Key or the key-number
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.org to find a
bonded/registered locksmith who
performs 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 number in more than one
place, do not record it in a way that
can be easily identified and associ-
ated 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.
