Take a picture of the ESD protection ICs on the data lines going from the switch rows and columns to the MCU.

There's numerous people reporting the same problem. Just by having an ARM CPU doesn't make it immune. You still have to provide ESD and surge protection circuitry on all data, power and ground nets of the PCB. It sounds like it was either designed incorrectly, or skipped all together.

Nope, it's the correct one. It was rhetorical and you totally didn't get it. ;)
