Unresponsive Del key

[Omroth]

I've been using my Cosmo for two months, and just this week the Del key is intermittently unresponsive.  I have to push on the very left hand side of it to get a reliable response.

Any advice?  Thanks.

There might be some dust or just "something". Try to lift key up, clean and reseat key back.
