KEYS AND DOORS
10
KEYS
11L025-3
1 Master key (black) – The master key works in every
lock. For your Lexus dealer to make you a new key
with built–in transponder chip, your dealer will need
it.
2 Subkey (gray) – The subkey will not open the trunk,
trunk main switch and the glovebox.
3 Key number plate – Keep the plate in a safe place
such as your wallet, not in the vehicle.
The master key and subkey each have a transponder chip in
their key head which is very important for the immobiliser
system function, 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 things locked in the trunk or glovebox when you
have your vehicle parked, leave the subkey with the attendant.
Since the doors and 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.
You should also put a copy of the key number with your
important papers.
