KEYS AND DOORS
11
A transponder chip for the engine immobilizer system has
been placed in the master and valet keys. These chips are
required for the
system 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 locked in the trunk or glove box when using
valet parking, leave the valet key with the attendant.
Since the doors and the trunk lid can be locked without a key,
you should always carry a spare master key in case you
accidentally lock your keys inside the vehicle.
If you should lose your keys or if you need additional 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.

NOTICE
When using a key containing a transponder chip,
observe the following precautions:
