Keyboard issue with MBP

[rockinrocker]

Hi-

There're are a few keys on my 2011 MBP that are getting a little wonky.
Mainly the G and F, but occasionally the A S and D as well.

Basically they'll just stop working for a few keystrokes, until I repeatedly push on them a bit harder, then they'll start working again. Sometimes I have to give them a pretty hard push to get them to work.

Any suggestions (short of taking it in) that I could try?

Thanks

Cleaning out the machine of dust will probably do it the workd of good.
