I hear a clicking noise when I type

I hear a clicking noise when I type the "C", "Space Bar", "W", and "D" keys. It started with the C key then spread to the others. No damage or spills to my laptop occurred. Why? and what to do?

How old is your Laptop?
Normally that´s aging, dust and abrasion of the keys.

You should buy a can of compressed air and try blowing the area out. There might be tiny crumbs under the keys.

You've been using those buttons too much and now they're aging.
