Suddenly iMac does not recognize wireless keyboard.

Keyboard light is on (so batteries are good) but the computer and keyboard are not communicating. I am unable to enter password to log onto computer.

The following will require any USB keyboard and mouse. If you don’t have them, borrow or buy them, they are inexpensive!

Connect the USB keyboard and mouse to the computer.
Open System Preferences – Bluetooth
Un-pair the wireless keyboard and mouse.
Turn off Bluetooth
Restart the computer in Safe Mode per the directions in How to use safe mode on your Mac - Apple Support
Restart the computer normally.
