A single key on my laptop wont work!

[cma.ericajhane17]

I have an hp laptop, and the letter A key wont work. There are times that the key works and there are times that it doesnt. I tried uninstalling the keyboard driver and rebooting the device, and i already tried long pressing the power button, i tried cleaning the keyboard, but it does not help. Please help.The key still randomly works whenever it feels like.

This is most like keyboard starts failing. The replacement is kinda cheap.
