Q: Apply wireless keyboard no longer will connect to MacBook Pro?

I'm on the latest version of OS and my Apply wireless keyboard has been working find for a couple of months until today.  It will not even find the keyboard when i go into settings and try to setup a wireless keyboard.  If i go into bluetooth settings, the keyboard shows but not connected.  If i click and tell it to connect it will not.  My Apple wireless mouse is working fine.

I changed the batteries in my keyboard still nothing.  I restarted my macbook and still nothing.  I can take my wireless keyboard and it will sync up fine with my iPad.

Any suggestions?

thank you
