2013 Sierra iMac keyboards not working

Overnight my iMac Bluetooth keyboard has started to not recognise certain keys (delete, shift, space, caps lock) and is also delivering different letters than those selected on the keyboard (g for a) I have tried 2 keyboards and both have similar but not identical issues (eg one recognises ‘a’ but not delete, shift etc)

any advice would be greatly appreciated

thanks

iMac 21.5″, macOS 10.12

A few things to try.

Try a wired keyboard to see if the problem is still there
Start up in Safe Mode and see if the problem has gone
Reset the Bluetooth ( https://osxdaily.com/2015/12/15/reset-bluetooth-hardware-module-mac-osx/ )
Reset NVRAM, PRAM, SMC ( https://www.macworld.com/article/224955/how-to-reset-a-macs-nvram-pram-and-smc.html )

Hi Mal-S

I tried everything you suggested as well as reloading Sierra. No success.

I got an old HP wired keyboard from my daughter and...success.

Not ideal but solved the problem for now

Thanks
