Logitech k340 reciprocal coupling of keys
I own a Logitech K340 keyboard. It has started behaving oddly recently, producing incorrect characters in certain situations. For instance, typing 't' results in 'tz', 'z' yields 'tz', 'o' displays '<space> o', and pressing space produces ',space o'. It appears some keys are now linked in reverse. I've tried restarting the computer, updating the driver, cleaning the keyboard, performing a factory reset, and replacing batteries, but the issue persists.
Welcome to the forums, newcomer!
That's a membrane keyboard. You could try and take the keycaps off both T and Z and see if there's any debris or dirt under said keycaps. I'd also try and disassemble the keyboard and see if there's any dirt or debris between the membrane layers. You can use a soft microfiber clothe with a mild soapy solution to wipe the membrane layers, if you can get tot eh membrane layers, that is.
