When my iMac started up this morning, it couldn't find my wireless (Apple) keyboard. No problem, I thought: batteries must be flat. I replaced them... and still no joy.
Must be a fault with the Apple keyboard, I thought. Then I tried it with my iBook and it works fine. Must be a Bluetooth problem with the iMac, I thought. No, the wireless mouse works fine.
So I reset the SMU. No change. OK, I thought, I'll reset the PRAM... except that without a keyboard, that's impossible.
Here's what happens: on start up, nothing happens when I tap the keys so I cannot input my password to log on. After a few minutes, the iMac starts searching for a keyboard and, after two or three goes, 'finds' my keyboard. But instead of asking me to type in a pairing password it simply says the keyboard has been paired... except it hasn't. I'm really stuck. Does anyone have any ideas?

As no-one seemed to have an answer to my problem, I took iMac and keyboard to my local Apple service agent. They diagnosed a software problem and, hopefully, have solved the issue. I'll know for sure later today when I pick it up.
