The lock of the owner's newspaper box is broken. Should the property company manage it?

First of all, we must distinguish between situations:

1, the newspaper box presented with the subscribed newspaper is maintained by the unit responsible for delivering the newspaper.

2. The letter box set by the post office shall be maintained by the post office.

3. The letter box set by the developer is maintained by the property, but the owner needs to repair and replace the lock by himself, which is the same as the door lock of the owner's house.
