Fatek Plc Password Unlock Software May 2026
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.
Warning: bypassing or removing passwords from industrial controllers can violate laws, void warranties, and create safety risks. This post explains the landscape, legal and safety implications, legitimate recovery options, and safer alternatives for dealing with locked Fatek PLCs.
Before you download random software, try these official routes:
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.
Once you get back in, follow the "Golden Rule of PLCs": Always export your source code to a PDF and store it on a server. Better yet, disable the password on development machines and only use "Run Mode" passwords for production.

The Reality of Fatek PLC Password Unlock Software Losing the password to a Fatek PLC (Programmable Logic Controller) is a common headache for maintenance engineers. While third-party "unlocker" tools exist, they come with significant risks to both your hardware and cybersecurity. 1. Understanding Fatek PLC Security
Fatek PLCs, particularly the FBs and B1/B1z series, use WinProladder software for programming and security configuration.
Protection Levels: Fatek systems offer multiple security tiers, ranging from basic password entry to advanced user-level permissions (up to 15 levels).
Read/Write Protection: Passwords can be set specifically to prevent unauthorized "uploads" (reading the program from the PLC) or "downloads" (writing a new program to it).
The "5% Limit": In some versions, if the PLC is set to high-security mode or has failed multiple login attempts, it may display a "5%" status; in this state, standard unlocking is generally considered impossible without a total wipe. 2. Available "Unlock" Solutions
While Fatek Automation Corp. does not provide a public "backdoor" tool, several third-party and unofficial methods are often cited:

Unlocking a password typically depends on whether you need to recover the existing program or simply reset the unit for a new project. Professional Recovery vs. Reset Official Support
: If you are the owner of the PLC and have lost the password, the most reliable method is to contact Fatek Automation Support Factory Reset
: If you do not need the current program, you can "unlock" the PLC by performing a factory reset. This wipes all user data and the password, allowing you to download a new program. MMC Card Method Critically, Fatek does not store passwords in a
: On some models, you can create a new program on an MMC card and insert it into a powered-off PLC. Upon powering up, the PLC will overwrite the old, password-protected program with the new one. Unofficial Unlocking Tools
While various third-party services and software tools claim to bypass Fatek PLC passwords, use them with caution as they often carry security risks or may fail depending on the firmware version. Third-Party Services : Sites like PLC Unlock BD
offer tools for FBs series PLCs (up to V5.83) that claim to reveal the password without data loss. Limitations
: If the PLC screen shows a "5%" status during a password request, some tools may be unable to bypass the protection. WinProladder Versions : Some specialized versions of the WinProladder software
are rumored to bypass project-level passwords, but these are not official releases and should be used at your own risk.
: Attempting to bypass a PLC password may violate licensing agreements or security protocols. Always ensure you have the proper authorization before attempting to access protected hardware. using an MMC card?
I’m unable to provide or help locate software designed to bypass or unlock passwords on Fatek PLCs or any other industrial control systems. Unlocking a PLC without proper authorization may violate laws, terms of service, and safety regulations. It can also disrupt machinery, endanger people, or void warranties.
If you’ve lost or forgotten a password for a Fatek PLC, here’s what I recommend instead:
If you’re locked out of equipment you own or manage, working through official support channels is the safest and most reliable path.
When you Google "fatek plc password unlock software," the results are a minefield. Let's categorize what you will find.
Several independent developers have created software that leverages a vulnerability in the Fatek communication protocol (Fatek Format). These tools send a specific packet sequence that triggers a "dump" command normally reserved for factory debugging.
Examples discussed on forums (use with extreme caution): Disclaimer: This post is for educational purposes for
How it works (simplified):
The tool sends a malformed "Read Memory" request to address 0xFFFF, causing a buffer overflow that returns the memory block containing the password hash.
To understand why unlocking is difficult, you must understand why the lock exists in the first place. In the industrial sector, source code is intellectual property.
