Volume up key/command key problem

I am having a problem on my 13'' ultimate. The volume up key is currently not working and this is the second time this has happened. The first time it lasted for a couple of minutes and then all of the sudden started working again. This time I can't get it to work. When this happens my right command key also stops working which is pretty strange that it happens to both keys at the same time. I was wondering if anyone else has had this problem, and what should I do with my air? I don't want to have to get an entire new laptop just because of a couple of keys not working unless I absolutely have to.

Update: After about 5 minutes with the key not working, I plugged it in since my battery was low and after it was plugged in for half a minute the keys started working again. I am sure this problem will continue to happen though, so should I do something about it?

 

Thanks for the help. I ended up having to send take my air in since the keys stopped working completely. They then took my air and sent it to be fixed, they have to replace the keyboard...of course. It's been hard having to live without it!
