Using the mechanical keyTo take out the mechanical key:
Electronic keys: Slide the release
lever and take the key out.
Card key: Press the lock release
button and take the key out.
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.

■When required to leave the vehicle’s key with a parking attendant
Turn the luggage security system on as circumstances demand. (P. 3 6 8 )
Remove the mechanical key for your own use and provide the attendant with the

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 aircraft.
●If the battery cover is not installed and
the battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive termi-
