How to UNpair keyboard without original computer

I'm trying to pair an Apple wireless keyboard with my Mac Pro. The keyboard came from my IT department and has been used with other Pro's before. My Pro can discover the device but will not pair.

I've read the the device must be unpaired from it's previous computer. However that computer is no where to be found.

How can pair this keyboard with my computer? Do I have to factory reset the device? If so, how do I do that?

I'm using a PC keyboard for the time being and it's killing me.

Mac OS X (10.6.5)

I had exactly the same problem - I figured out how to force it into pairing mode, though its not intuitive and kind of a pain. With the keyboard off, you hold down the power button on the keyboard and the LED will start to blink, do not let go of the power button. Open up the bluetooth add device wizard, and the keyboard will appear there as long as you're holding down the button. Select the keyboard and pair it, when it says "Connecting" you can let go of the power button.

I am willing to bet this process will work for most BT keyboards.

I have struggled with this and found a consistant solution.


  1. take keyboard and laptop/desktop to an isolated place where you know there are no bluetooth signals.
  2. turn off bluetooth in control panel
  3. take off battery cover to keyboard to make sure its off
  4. screw battery cover back on (dont turn on keyboard yet!)
  5. turn on bluetoothin control panel and then press power on keyboard
  6. when you see the green light blinking on the keyboard top right corner click PAIR on the control panel


This works for me every time. Hope it helps others.

I had similar problms. I suspect the keyboard noticed the mac it was previously paired with, so refused to go into pairing mode. Steps to fix:


1. Remove keyboard batteries.

2. Turn off bluetooth on your mac.

3. Replace the batteries and turn on the keyboard.

4. This made the keyboard go into pairing mode.

5. Turn on bluetooth on the mac.

6. Follow your nose.

I didn't have exactly this problem - ie my keyboard was always linked to my imac but one day decided to stop working. I did all the usual stuff and more - including trashing bluetooth plist and resetting SMC - all to no avail. However, this simple little gem worked first time! Thanks c76mb

If you have an aluminum apple wireless keyboard that won't pair (mind didn't all of a sudder after a year when I changed the batteries) read Colin Holgate's reply. After countless hours of reading posts this was the true fix.


Seems to be critical that you first turn off set up assistant,then hold in power button until blinking on keyboard and don't let go and finally click bluetooth icon and set up bluetooth device.


Thanks Colin!

This procedure works fine if you are logged in and have access to System Preferences. But if your keyboard is not bluetooth connected when you startup your mac, all you have is the login screen and the only thing that works is the walking into the backyard procedure (getting more than thirty feet away from your computer until the green light starts flashing.

I had similar problems with unpairing the 2009 alum bt keyboard. None of the solutions I saw here worked but this one did:


  1. Switch off the keyboard by holding down the power button for at least 3 seconds
  2. Click the Bluetooth icon in the menu bar
  3. Click on “Set Up Bluetooth Device”
  4. Turn on the keyboard by holding down the power button, BUT DO NOT LET GO OF THE POWER BUTTON. It must be kept held down through the entire process.
  5. The Setup Assistant will find the keyboard, so click the name of the keyboard, and then click on “Continue”. Make sure you are still holding the power button down.
  6. You will be prompted for the Pairing Code. You can now release the power button, type the pairing code on the keyboard and then press return. There will be a slight delay whilst the pairing completes (a few seconds)
  7. The keyboard will now be Paired.

So just to clarify, the trick is to continually HOLD DOWN THE POWER BUTTON.

Good Luck - Urban Cowgill

The solution that I found comes from:

http://davemeehan.com/technology/how-to-reset-an-apple-wireless-bluetooth-keyboa rd-mouse-or-trackpad

Here my interprestation:

Hold for tree seconds the power button until the mini led turns off

Press and Don't release the power button, the secret was to not let go (Keep pressing until you finish next step)

Do the pairing "Tap Connect". Keep the Keyboard as much as closer to the iPad (or the device your are trying to pair it too)

My problem was that the keyboard was pairing to some other device, rpobably my Apple TV but this worked for me

My problem is inverse

I have a mac mini and an iMac in the same room, and the iMac keeps connecting to my Mac Mini bluetooth keyboard, despite already being connected to the iMac bluetooth keyboard

When i try to remove the extra keyboard on the iMac, by clicking the 'X' button which appears in Bluetooth settings when i mouse over it, it tries to pair instead of removing it. Right clicking on the keyboard in Bluetooth settings does not offer 'remove' as an option, and only offers to pair it. I cant seem to find a way to get the iMac to forget this keyboard, and clicking the X button does not remove it, rather, begins the connecting process. Every hour or so im typing on my Mac Mini, and all of a sudden i see the iMac typing itself away too. Absolutely incredible that there is no option to completely forget or remove the keyboard from the iMac registry
