If all keys function properly except for the spacebar then your spacebar is no longer functional, make an appointment and take the keyboard to your local Apple Genius bar. You will need the serial number of your iMac in order for Apple Care to cover the replacement.

I have been having this happen to me off and on (though it is on my MacBook) and after scouring this website I have found two helpful tips, and I have no idea if these will help you as an iMac user:
- For the MacBook It seems to be related to batter life. It usually happens to me when I have less than 45 minutes left on my battery. When I plug it in, it sometimes takes care of the problem.
-When that doesn't work, I can usually get it working by toggling Num Lock (fn + F6), which usually takes care of the situation!

I did not have to replace my keyboard (though I do remind you that I am working on a 5 year old MacBook, not an iMac. I actually haven't had the issue for about 5 months now. So, all I can really offer is the toggling of your NumLock. Which, if you have a MacBook is done by holding the "fn" key and tapping F6. I usually tapped it a good 5 or 6 times, which seemed to sort of "wake it up" and if that didn't work (which meant that I had actually turned NumLock "ON"), I toggled one more time to turn it "OFF" If that doesn't work, I don't know what else! sorry!
