Keys stopped working on iMac Apple Wireless Keyboard

One or more keys on the keyboard do not respond

If keys on your keyboard don’t work

though most solar powered devices have a rechargeable battery that the panel charges

otherwise it would stop working at night

and sooner or later all rechargeable batts die

This is weird.. because at exactly the same time very similar keys stopped working on my wireless keyboard for my imac which is also 2009 model!

The keys that stopped working for me are also exactly the same. tab, delete key, down arrow and space bar!

This cant be a coincidence. This is obviously a bug, or a virus or something to do with software... too much of a coincidence.. Is there anyone else who has the same problem?

I have a keyboard with the exact same issue, same keys suddenly died.

I have a 2009 iMac with a similar problem, but P, O, Del, M, N, B and CAPS are not working as well.

I don't think it's a software issue in iMac, because the problem persists when I connect the wireless keybord to the iPad.

Really frustrating. Did you guys discover a solution. If I take the keyboard to an Apple Store to be replaced (no Apple Care for this iMac), how much it will cost?

I don't know if it is the same issue but I was annoyed because some keys on my wireless keyboard stopped working as well. It was mainly the backspace and the directional keys. However, after toying around with it for a while and watching the keystroke input from the "Keyboard Viewer" option, I realized that my "fn" key is getting stuck at random times and this is causing the other keys not to work. This still is a flaw in the keyboard but at least I have figured out what was making it act up. Maybe it is something similar with yours.

I'm having the same issues. It's doing it to my entire keyboard. I mean the entire keyboard. I have no idea what I have to do with this thing.

I am having the same exact isseue! itsreally annoying!

My problem occurred at the same time. About 2 weeks ago (mid-October). Same keys, plus but also extends to the arrow keyes and the music (Function Keys).The function aspect workd fine, fbut the muisic keys feature does no. thisis ridiculous. my post should not look this f'd up,but the **** keyboard is killin'me.

oh,the apostrophe doesntwork either.

YOUHAVEt topress FN with the spaceBar toget it to work. AmajorI PainI in the @$$!!

Pleasehelp!!!

Same problem here. About a week ago, my "down arrow" key stopped working. Now when I press "down arrow" I get a row of commas. All the other keys are fine.

i have the same problem with my Mac OS X Lion 10.7.5 Mid 2011 wireless keyboard. the keys that aren't working are X,W,S,TAB. am currently using the 'keyboard viewer'. it is something to do with the system preferences or just need to replace this keyboard?

I have same problem but my keyboard non wireless...
My afected key is R, F, V, and Backspace

The keys that stopped working for me are also exactly the same. tab, delete key, down arrow and space bar!

How can this happen to more and more keyboards?

What to do? just buy a new one? demand a replacement in the store?
