The hotel door lock is dead. How to open the door?

There are generally two ways to open hotel door locks: swiping the card to open the door and mechanical key to open the door. In general, use the room card to open the door. When the battery of the door lock is dead or in poor contact, you can't open the door with the room card, but you can use the key to open the door. The keyhole of a door lock is generally located under the door lock.
