Apple Wireless Keyboard (A1016) detected but will not pair

I had similar problem with KB not connecting to desktop. After trying many things, I realised that there was some sort of interference with my iphone, ipad and laptop. All three had the same KB paired with them. I turned off Bluetooth on all of them, restarted desktop and it is fine. Hope this works for someone else.

Try resetting the PRAM and SMC.

Hello:

At this point I would suspect a KB failure. You could take it to an Apple store to see if it would work there.

Had the same problem this Am and I fixed it by doing two things. Since I did them both simultaneously, I'm not sure which one did it, so there goes the scientific method:

1. I used Energizer batteries instead of Duracell. I had a problem years ago with Maglites not working and the company advised me to try Enrgizers which fixed the flashlight. Not sure if it applies, but I did use Duracells when the problem started, then switched them to Energizers.

2 Trashed the Bluetooth preference file. Go to Home (your User folder) > Library > Preferences, find blietooth preferences, then drag it to the trash, but don't empty the trash. Do a restart. That forces the OS to build a new prefs file.

I did those two things, the Mini immediately found the keyboard, asked me to type in code, paired and is now working like a champ again.
