They keyboard may have died, however before giving up on it, please reset the SMC 2-4 times with all wired peripherals disconnected and then test. You need to do this multiple times as resetting the SMC does not always work the first time.

Instructions for doing an SMC reset are in SMC Reset

You can also try restarting in Safe Mode too, instructions for that are in Use Safe Mode to isolate issues with your Mac
