Keyboard issues -some keys not showing

Since upgrading to Catalina several weeks ago, I am seeing constant issues with typing. The "K" key is one of the worst offenders, but other keys skip and leave blanks or just record the next letter in a sentence. Using default Apple blue tooth keyboard, USB and wireless have same result. ANSI wired keyboard works more reliably. I reset the PRAM last night and it made no difference. I can't type anything without fixing each affected word. Some typing issues existed prior to the Catalina upgrade, but Apple tech was unable to identify a problem.

What causes this and how to fix?

iMac 27" 5K, macOS 10.15

Please reset the SMC several times with all external peripherals disconnected. The reason to do it several times is a SMC may not always work the first time and you want to give it an adequate chance. Instructions are in SMC Reset

Thanks! I have only done one additional reset so far and have been testing. I may do one more, but there's definitely an improvement now.
