If you have forgotten the 'keyword' your only option is to have the PLC's memory wiped and the program reloaded. (A mitsi dealer can do this) You have to have the original program for this.

The stop switch is linked mechanically to a stop switch on the PCB, maybe this link has failed.

You will not be able to go online with the plc at all without the keyword.
