Q: Keyboard not responding

My wireless keyboard for iMac only responds to function keys (ex: shift, up down,Fn, control, option, command delete and  F1 through 12)  When I try to type numbers or letters there is no response.  Also caps lock does not respond.  When I go to the Mac itself, it shows it looking for the keyboard but never finds it.  I changed batteries and tried online keyboard tests. Any ideas?

iPod touch, iOS 3.1.3
