Take out the mechanical key. The mechanical key can only be
inserted in one direction, as the key

key cannot be inserted in a lock

attempt to insert it.

store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the smart
access system with push-button
