Power off the S7-1200 CPU, insert the empty Siemens memory card, and power the PLC back on.

The simplest form of "unlock work" is not really an unlock—it’s a . If you do not need the existing program and only need a functional CPU, this is the fastest, safest, and 100% legal method.

The CPU will detect the transfer card and begin wiping the internal memory.

For emergency outages where Siemens’ turnaround time is unacceptable, third-party companies have developed hardware tools that perform S7-1200 password unlock work by exploiting side-channel vulnerabilities or bootloader backdoors.

Note that if the entire CPU configuration is password-protected, the software will prompt for a password before allowing this action, making the physical memory card method necessary. Protection Levels

If you are dealing with a heavily protected system, or if the standard reset methods fail, the final option is to contact Siemens support or, if necessary, replace the CPU hardware, as a severely locked PLC may require factory intervention. (Maintenance) LED will blink, indicating the transfer is
