I bought an Inspiron 3585 in October 2019.  After a few weeks the spacebar stopped workng properly.  I took the laptop back to the shop and they replaced it under warranty.  Now the replacement is showing the same problem - it always "clicks" when I press it but sometimes doesn't generate a space unless I press hard in the middle.

Is it possible to unclip the spacebar and clean underneath it?  This was possible on my previous Inspiron 510m.  I don't want to force it in case I break it?  Can someone at Dell tell me if the keyboard itself can be replaced as a separate assembly.
