Unlock Omron NX / NJ / NP Series PLC Password
Recover access to a password-protected Omron NJ or NX series controller programmed through Sysmac Studio. The protection involved is Omron's own "Data Protection" function — confirmed in Omron's own security advisories as the mechanism guarding programs on these controllers — and on some units a separate, controller-level authentication layer as well. If you'd rather have it handled, I provide manual Omron recovery support — done personally, with nothing sold or downloaded from this site.

Who does the recovery?
I do, personally. Every job is manual — it isn't automated with a tool and it isn't resold to anyone else.
Do I have to own the equipment?
Yes. I only help owners and authorized maintainers regain access to their own projects — in line with the authorized-use-only policy on the channel.
Do you sell a tool or a download for this?
No. There are no tools for sale and no downloads on this site. Recovery is a manual service I perform or guide you through.
