Why my Left [Ctrl] Key dosen't work any more ?

[Hackoo]

Hi !
In the last two days i have remarked that the left [Ctrl] dosen't work any more,
so i can't use [Ctrl]+A or [Ctrl]+C or [Ctrl]+V
So How to fix this issue
Thank you !

1) Remove the key and see if there is anything preventing it from fully depressing
2) Try a different keyboard. If it works with the second keyboard - well, you can guess the rest
