Bluetooth keyboard always wants to pair I have a MacBook Air in my office that prompts to pair to a BlueTooth keyboard every 5-10 seconds. 

I turned BlueTooth off/on. Made sure it is not discoverable. Restarted. Run updates. Reset PRAM. Reset SMC. Deleted com.apple.bluetooth.plist (~/Library/Preferenes/ and /Library/Preferences/). Removed the offending  and  from the above plists. With no luck.

I have also taken another computer up next to the MacBook Air running iStumblr as well as the Set Up Bluetooth keyboard and the keyboard cannot be found by either the MacBook Air or the other Mac. But the prompts still persist on the Air.

I have not been able to find any other suggestions re: how to stop the prompts. 

Finding the keyboard is going to prove tricky as it is in a large office environment.

Any other suggestions?
