not 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 mechan-
ical key together with the electronic key.

properly, you will need the mechanical
key. ( →P. 454)

tronic key only.

When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons 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.
