Q: Wireless keyboard won't connect

Apple wireless keyboard (2009)

Mac Pro 5,1

Lion 10.7.5

 

Apple wireless keyboard won't connect after changing batteries. It is listed as a paired device under Bluetooth preferences but using the 'Connect' option fails. The keyboard does not go to discovery mode.

 

I'm answering my own question because there seems to be a lot of voodoo around the problem. The following worked for me after trying a lot of different stuff.

 

  1. Go to System Preferences -> Bluetooth. Delete the keyboard from the list of devices by pressing the '-' button.
    Alternatively you can delete the plist file but it shouldn't be necessary if the keyboard is the only problem. Deleting this file means restarting all other bluetooth devices to force them to reconnect. The plist file is in /Library/Preferences and is called com.apple.Bluetooth.plist. 
  2. Take the batteries out of the keyboard and reinsert them - don't power on the keyboard yet. This puts the keyboard in discovery mode the next time it's switched on. 
  3. In Bluetooth Preferences press the '+' button to add a new device.
  4. When the Bluetooth Setup Assistant is displayed hold down the power button on the keyboard and don't release it! The keyboard should now appear in the list of devices. 
  5. Press 'Continue' - remember to keep pressing the keyboard power button while hitting 'Continue'. You should get an 8 digit passcode from the setup assistant. 
  6. Now release the keyboard power button and enter the passcode. 
  7. Press return - the keyboard is now paired.
  8. Go to back to Bluetooth preferences and select the keyboard in the device list. 
  9. Press the gear icon and select 'Update Services'. Without this last step you may have to reconnect the keyboard from the Bluetooth menu after every startup. 

 

Hope that helps.

    Thanks - that was my problem. iPad with bluetooth on (and previously paired) too close.

    This procedure works fine with my iPad Air, except for the final step. I'm running iOS 9.2.1. In the final step of the pairing procedure given, I am unable to find "Update Services." Consequently I've had to go through this otherwise flawless procedure many times. Surely there is a workaround that will keep the pairing of the wireless keyboard.  Thanks for any help someone may provide.

    thats all fine and dandy IF you can get it, Ive been stuck on log in screen for a WEEK because my stupid keyboard wont pair - so i cant enter password. it worked fine before changing batteries amd Ive gone through countless batteries.

     

    it says "make sure it is in discovery mode" how the heck do you do that? it is on, ive tried holding down power pbutton for 5, 10, 30 seconds.... green light is ON - but apparently i have to go BUY a usb keyboard to fix this??

    Pairing is when the wireless keyboard blinks... and that only takes 5 seconds or so... do you have any bluetooth items paired in your Mac at all ? What OS is it ?

    What resolved this problem for me was not understanding that I had a whole

    load of Bluetooth devices in my house that the keyboard could "see".

     

    It was only by taking the keyboard out of my house and walking 100m up the

    road that I could get it to start the flashing pairing sequence again by

    pressing the power button.

     

    Back in range of the computer again and it paired without a problem.

    THanks, it will only blink 2 or 3 times amd turns off, i see the next comments about leaving the house - but i already ordered a usb keyboard on amazon for $14 since ive been trying for days to get it reconnected. It worked perfectly until i changed batteries amd i know they work because i swapped with another keyboard amd same thing.

    I was doing this - thanks - but have found a quicker way that works for me:

     

    I power off the keyboard by holding the button until off. Then I go to my Bluetooth menu and click the dropdown so I can see my listed keyboard and select "Connect". Then I just hold the power button on my keyboard until it connects again and then let go.

     

    That works for me when my Mac 'loses' my keyboard.

    I could not get my keyboard and mouse to connect to my mac pro no matter what I did.  Turns out I had my laptop open three floors away, and it had grabbed the keyboard and mouse.  Sometimes it's not a computer problem ...  :-)

    Thank  you. I was starting to think my keyboard was connecting to a neighbor and was losing my sanity. This worked  out perfectly for me on the first try!

    Cheers

    I signed up to thank you. 

    Succinct s***.  Digging out an old laptop running 10.6.8 to keep on working and your instructions saved me an hour of frustration.

     

    I love your bones,

    this used to work, but my Bluetooth preferences no longer has a + or – option and nowhere can I find an "add new device" link. Since I've deleted my keyboard from the list I'm a bit stuck.

    Any clues?
