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 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.
