Plug in keyboard not working.

I have an iMac (21.5-inch, Late 2015) with Mojave 10.14.6. It came with a wireless keyboard. I replaced this with an extended Apple keyboard (not wireless). I plugged it in and it worked fine. After several weeks it suddenly stopped working. What could have happened?

Please reset the SMC 2-3 times and it should work.
