Wireless keyboard adding extra characters

[Katmc101]

My keyboard worked fine all morning and around lunch started adding extra characters. For example f becomes 5f, k becomes =k , j becomes 6j, a becomes 'a and S takes me to a new screen. 

I have tried changing batteries, running the troubleshooting (said no problems), checking the keyboard settings, updated and uninstalled the keyboard driver, did a system restore to several days ago when everything was fine...nothing has fixed it. My onscreen keyboard works fine but that is not a practical solution and I work from home so I could really use a working keyboard.  Help!
