I'm routing a PCB board with Altium. Today I find when my mouse hover on the pads, it shows some shadowed "key" symbols. What's the meaning of them?

The "key" symbol means that the specific track/pad/component is in locked position, so it is unmovable. Right click on the [specific item \$ \longrightarrow \$ properties \$ \longrightarrow \$ uncheck locked checkbox] and the "key" symbols will be gone.
