Password hacking is a little frowned on here for very good reasons.

Why can you not contact the original programmer/company to get this done or get the password ?

Why do you need to modify it ?

Do you know what you are doing ?

One option since the machine manufactor did not lock the program is to contact them and order a new CPU that is programed then you will have a unlock program.
