if u are using a laptop then take it to a service center or if u can then open the lappy and clean the dust under the keyboard & if u are using a pc then just change the keyboard...

If you have issues with just 1 single key, try removing it from the keyboard gently with a screwdriver or just your hands. Clean under the key and be careful not to scratch anything underneath.
