Can't pair apple wireless keyboard

Solution 1:

If only one number key is working, it sounds like a hardware issue. My brother had a wireless keyboard that flaked out and only certain keys functioned (although in his case it was from a liquid spill).

Do you have any other Bluetooth-capable device to test with? Any iOS device can pair with the keyboard to test it.

Solution 2:

For posterity, some troubleshooting on this exact same problem...

After reading the question and answer here I was ready to throw the keyboard in the trash, but then thought that if two people have such an odd failure maybe its just a bug that one can work around.

So, after being unable to type anything but 0 and enter and watching the connection attempt fail, I clicked a button on the failure screen that allowed me to then choose an alternate passkey. It was pre-populated with 0000. I played around with connecting again but the enter key would not highlight until I typed eight zeros instead of four. I tried a few times and then noticed for whatever reason the custom setting was back to eight random digits.

I decided to start over, clearing out the list of bluetooth devices. On my next attempt, I typed 00000000 and enter for the passkey and waited for the failure. I then selected the custom passkey setting which was now populated as 0000. I reattempted and was asked to type 0000. I did so, and even though the screen did not show I could hit enter - presumably because it wanted four more digits - I hit enter anyway. And it paired.

I am typing this with that very keyboard. Sounds great. Except this: the keys 1 through 9 still do not work, nor do the symbols on those keys when holding shift. Note I copied/pasted the one and nine digit from elsewhere into this answer :-)

So sad.
