Every key on my Razoe Black Window Ultimate keyboard is recognized by Windows 7, except the 'j' key. Nothing happens when I hit it. I've moved the keyboard to my Macbook and it works fine there. The keyboard driver is up to date.

Any ideas on how to fix this?

Does it work on other keyboards? – Darth Android Aug 24 '12 at 19:42
J is a numeric keypad key. Try toggling NumLk a few times. – Daniel R Hicks Aug 24 '12 at 20:31

There's really no reason one letter should stop working unless you have mapped it to something else on the Windows machine. I recommend removing all of the software and drivers for the keyboard and re-installing it. If that doesn't work, I would contact Razor technical support and see if this is a common issue. But I suspect it's just mapped to something else, being a gaming keyboard and all. Check your startup processes and see if there's anything weird in there as well. (type msconfig into Run)

Turns out there was a macro set against the J key that did nothing. I have no idea how it got there, but when the J key was pressed the empty macro ran. I removed the macro and it works correctly now. – TERACytE Aug 29 '12 at 16:51

Steps for fixing this issue:

  1. Open Razer Synapse.
  2. Select keyboard.
  3. Click on the key which is not working.
  4. Select any other function than the default.
  5. Click Save.
  6. Then click on the key once again and select default again.
  7. Click Save.
