the card key should be used only if a
problem arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical

using a pen tip etc. If it is still difficult to
pull it out, use a coin etc.
●To store the mechanical key in the card

■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 acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
(The card key battery life is about a year
and a half.)
