Unlocking a Koyo (or similar) PLC password must be approached carefully: only with authorization, by qualified personnel, and preferably with vendor involvement.

When in doubt, engage the manufacturer or an authorized service provider rather than attempting uncertain bypass techniques that risk equipment, safety, and legal exposure.
