The key to the gate is broken. Is it related to the weather?

The key to the gate is broken, which is related to the weather. When the outdoor door is locked, it is easy to rust under the influence of wet weather or rain, and sometimes it is locked. When you open the door again, you may not be able to twist it, and you may break the key in the keyhole. You should drop some oil in the keyhole every once in a while, which will reverse this situation.
