The door to the room is locked, how to pick the lock?

1. When the person is inside, find a small piece of iron wire. There is a small hole at the neck of the handle. After the handle is detached, pry open the protective cover.

2. There are two fixing screws. Try to turn them open and push the lock body out.

3. When only the latch tongue is left, find a pair of needle-nose pliers or a flat-blade screwdriver, drive the latch tongue horizontally without letting go, and then push the door back open.

4. When you are outside, use hawk-nose pliers or water pipe pliers to grasp the handle of the horn lock and twist it hard, take it out, then knock out the lock body, then find a pair of needle-nose pliers or a flat-blade screwdriver, and remove it. The latch tongue drives the hook to pull horizontally. Don't let go. After you let go, it will bounce back and then push the door open.
