Depending on the degree of dirt/dust, it may—but isn't always—help to use a non-aggressive spray lubricant. I find Ballistol, which is colloidal paraffin in ethanol, works well for this. Ethanol generally doesn't attack plastics; it also acts as a contact cleaner, and the paraffin can help make the key move more smoothly.
However, if there is a lot of dirt in the key, the result can be even worse than before.
I find Ballistol in a spray can to be the most suitable for this kind of thing—it can be applied precisely with a small tube. It's also harmless, which helps when used on things you plan to touch again afterward.
Is it not making contact? Or is it stuck?

Put it in rice once, then the Chinese will come overnight and fix it. It's worked for me several times. Ching Chong.
Can you press it? Is it possibly stuck? How did you phrase the question then?
Maybe a letter that is not in the question will work.
Every time I press it, nothing appears!
I wrote this question on my cell phone!
Try restarting your laptop. Is it perhaps stuck due to dirt or liquid?
He probably wrote it on his cell phone. It was probably also recorded on his cell phone.
