Today, I found that the door lock at home was broken. What should I do?

Security guards should be informed, because it is their duty to protect the property of the community.

At the same time, as upstairs said, do your own safety measures, such as changing locks and installing miniature cameras.

There is also the ability to mobilize the owners of the community to press monitoring together in the corridor, so that this community will be guaranteed. I hope I can help you.
