function, tab and caps lock keyboard keys not working macbook air

Hi,


I have a mid 2012 macbook air running El Capitan 10.11.4. Today my tab, function and caps lock keys stopped working out of nowhere. I've clicked on the keyboard viewer and when I hit those keys it doesn't show them being hit. Does this mean it's a hardware problem? I just installed the latest update to El Capitan in the hope that it would come back to life, but it hasn't.


The tilda and shift keys are working as are all other keys. Any ideas?


Thanks!

MacBook Air, OS X El Capitan (10.11.4)
