Using the mechanical key
Take out the mechanical key.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be
inserted in a lock cylinder, turn
it over and re-attempt to insert
it.
After using the mechanical key,
store it in the electronic key.
Carry the mechanical key
together with the electronic key.
If the electronic key battery is
depleted or the entry function
does not operate properly, you
will need the mechanical key.
(P. 516)
Card key
The mechanical key that is stored inside the card key should be used
only if a problem arises, such as when the key does not operate properly.
If it is difficult to take out the mechanical key, push down the lock
release button using a pen tip etc. If it is difficult to pull it out, use a coin
etc.

When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circum-
stances demand. (P. 60, 356)

Key number plate
Keep the plate in a safe place, not in the vehicle. In the event that a mechan-
ical key is lost, a new key can be made by any authorized Lexus dealer or

number plate. (P. 515)
When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not
press any buttons on the electronic key while inside the aircraft cabin. If you
are carrying an electronic key in your bag etc, ensure that the buttons are not
likely to be pressed accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the air-
craft.
To store the mechanical key in the
card key, insert it inside while
pressing the lock release button.
If the battery was removed, reinstall
the battery with the positive termi-
nal facing the Lexus emblem.
