This is the most reliable professional method. You physically open the PLC casing, locate the serial EEPROM chip (usually a 24C02 or 24C04 on the main board), and read it using an EEPROM programmer (like TL866 or CH341A). The password is stored in plaintext or simple XOR at specific addresses (usually 0x3E0 to 0x3FF).
Pros: 100% success rate, no software viruses.
Cons: Requires soldering (or a clip), a hardware programmer, and hex dump analysis. It voids the warranty.
Restore from known program/configuration backups
Use manufacturer service mode or recovery tools
Re-flash firmware using official tools
Replace device or module
Critically, Fatek does not store passwords in a separate EEPROM chip that can be easily bypassed via hardware hacking (like some older Siemens S5 or Mitsubishi units). Instead, the password is embedded within the main program memory block. When you attempt an upload, the PLC's firmware runs a checksum routine asking: "Does the input hash match the stored hash?"
A brute-force attack via serial communication is almost impossible due to the slow baud rate (115200 max, usually 9600) and the PLC’s "watchdog" timer that locks communication after several failed attempts.

Searching for "Fatek PLC password unlock software" typically leads to third-party "crack" tools or bypass services. Using such software carries significant risks and ethical considerations. Understanding Password Protection in Fatek PLCs
Fatek PLCs (like the FBs series) allow users to set passwords to protect proprietary ladder logic and system configurations from unauthorized access or modification. This is a standard security feature used by original equipment manufacturers (OEMs) to safeguard their intellectual property. Methods for Addressing a Forgotten Password
If you are locked out of a Fatek PLC, the following approaches are generally recommended:
Official Factory Reset: If the program on the PLC is not needed and you only need to reuse the hardware, you can perform a factory reset using Fatek's WinProladder software. This will erase the existing program and the password, allowing you to upload a new project.
Contact the OEM: If the PLC is part of a machine you purchased, the most reliable and legal way to get the password is to contact the machine manufacturer or the original programmer.
Backup Programs: Check for offline backups of the .pjw project files. If you have the original source code on a PC, you can simply download it to the PLC again after a reset. Risks of "Unlock" or "Crack" Software
You may find websites or forums offering "PLC Unlockers" or "Password Bypass" tools. You should approach these with extreme caution for several reasons:
Malware Risk: These unofficial tools are often bundled with viruses, trojans, or ransomware that can compromise your industrial workstation. This is the most reliable professional method
Data Corruption: Attempting to bypass a password using unauthorized software can corrupt the PLC's internal memory, potentially "bricking" the hardware or causing unpredictable machine behavior.
Legal and Ethical Issues: Circumventing protection may violate intellectual property laws or service agreements with the original machine builder. Technical Resources
For legitimate programming and troubleshooting, refer to the official Fatek Automation documentation or the WinProladder User Manual.
