Using the mechanical key
To take out the mechanical key,
push the 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 cyl-
inder, 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 func-
tion does not operate properly, you
will need the mechanical key. (P.
