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.

This didn’t work for me cause I have a password, so when I restart my system it shows me the password space for me to type in my password.

Without the keyboard how do I do that?

Please I need help with this ASAP, anyone please.

Thank you.

Sometimes there may be an even simpler solution:


Locate the Power Button on your computer (it may be on the back of the machine).


Depress the Power Button for at least 10 seconds until the machine is off.


Wait 30 seconds.


Depress the Power Button again for about two seconds, until the machine turns back on.


Make sure your keyboard is turned on.


Wait for the Apple icon on the screen to appear and pass. The screen may display a message that says that the Keyboard is not recognized or not found.


Wait for directions to appear on the screen that guide you to an easy setup, simply by having you type in a displayed code and hitting the return button.


Voila! You're back in business.

You're awesome for posting this.

I was having problems pairing my keyboard with my iPad.


My keyboard (apple) would not go into discovery mode, the green light would not blink on and off. It would go on and then turn off.


Pressing and HOLDING that right side button on the Keyboard did the trick to enable my iPad to "see" (discover) it.


I'd give you the points if I could. Here's a thumbs up instead!

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??

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.

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.

that definitely should not happen, however I am curious why you turn off a Mac? I only reboot my macs once or twice a year. They recover from sleep so wonderfully, you really don't need to ever shut them off like you do with PCs. as for why they don't pair again, that is something of a mystery. Of course the old saying is make sure you have the latest operating system. But that's not much help. LOL my question back is really just why do you turn off a Mac?

Thanks for this hint - here's another one for anyone else who's stuck...


One thing that repeatedly catches me out is when I have paired my bluetooth keyboard with my Apple TV e.g. when you're sick of trying to type in email addresses and passwords using the remote. Without fail I will then forget to un-pair the keyboard with the Apple TV.


The next time I want to use my bluetooth keyboard and Macbook Pro in the living room, I will go through a 30 minute charade usually involving lots of cursing, and performing web searches to track down the problem. Then finally the penny drops.....


Hope this helps someone...let's face it it'll probably be me, when I end up doing exactly the same thing in about 12 months time.


Jon.
