Wireless keyboard refusing the pairing attempt
I have an Apple wireless aluminum keyboard. I've had it for a while and it was apparently paired with something in the past because it's name is "temp keyboard." Whatever device it was paired to, I no longer own.
Whenever I try to pair this keyboard - and I've tried it with an Apple TV, iMac running 10.8, an iPhone and an iPad - I get a "pairing unsuccessful" message. The Mac gives me the most complete message: "The pairing attempt was unsuccessful. The device is refusing the connection."
I've been all over these boards and tried every single recommendation. I've shut off Bluetooth in every device except the one I'm trying to pair with. I've tried holding down the power button. I've taken the batteries out for several days. Nothing works.
I haven't gone and deleted plist files and things like that because obviously the problem is with the keyboard, not the computer.
This is very frustrating because I want to use this keyboard with my Apple TV. Any other suggestions on how to reset this keyboard?
iMac, OS X Mountain Lion (10.8.2), i3, 12GB RAM
