The method of locking the door and being unable to open it is as follows:

1. When someone is inside: Find a small piece of wire or a small hole at the neck of the handle, and insert it flat.

When the lock body is pushed out and only the latch tongue is left, find a pair of needle-nose pliers or a flat-blade screwdriver. Drive the latch tongue horizontally and don't let go. It will bounce back after you let go. Then push the door open.
