How to reset your keyboard on OS X 10.10.4 My keyboard number pad has been messed up ever since I installed OS X 10.10.4. 

The numbers type as follows:  

when I press "1" increase volume key goes up as well.  

When I press "2" the ' key comes up as well.  

"3" some wired key. 

"4" ] comes up. 

"5" [ comes up. 

And "6" the equals sign comes up. 

And vice versa for the concurrent keys. 7 and 8 as well as their shift keys work fine, 9 highlights everything in shift and goes to the beginning. 

I've tried a reinstall and a separate Bluetooth apple wireless keyboard I have seems to work fine. 

Please help I've scoured the Internet for answers, nothing has worked.
You would have to open up your mac and unplug the keyboard cord power up the mac and then plug it would be a hard reset
