I notice when I push on the right side, the key pushes in perfectly meaning no tightness or whatever. But when I push on the left, I notice its a bit tougher and if you were to hear it, sounds like the key is touching against another key but its not. It just seems not as smooth. What can I do to make my left side push as smoothly as the right? Im thinking maybe it just needs some buttering up on the left side, maybe just a little dry. But how do you go about popping off a laptop space bar without breaking it. Is there any springs in voled.
