"KeyRead V20" refers to a specialized software tool primarily used by technicians and industrial professionals to extract passwords and unlock Mitsubishi Programmable Logic Controllers (PLCs). It is commonly associated with the FX series of PLCs, which are widely used in automated manufacturing and machinery. Key Capabilities of KeyRead V20
Password Retrieval: Its main function is to bypass or read the internal passwords (such as the 8-character keyword) that protect PLC programs from unauthorized access.
Unlocking Features: The tool is designed to unlock "locked" Mitsubishi FX PLCs, allowing technicians to upload or download ladder logic diagrams even when the original password is lost.
System Compatibility: It typically operates on Windows-based systems and interfaces with the PLC via standard serial or USB communication cables. Technical Context & Common Use Cases
The V20 version specifically targets older and mid-range Mitsubishi FX series hardware, which often relied on simpler password hashing compared to modern high-security units.
PLC Models: Frequently used with Mitsubishi FX0N, FX1N, FX1S, FX2N, and FX3G series.
Maintenance & Recovery: It is most often used during machinery maintenance when the original programmer is unavailable and the logic must be modified or backed up.
Security Disclaimer: Because this tool can bypass protection measures, it is strictly intended for legal maintenance by authorized personnel. Comparison with Automotive Tools
It is important to distinguish this from Mitsubishi automotive key tools. While Mitsubishi vehicles use "Fast Key" entry systems for remote start and keyless entry, those involve transponder chips and different programming protocols. KeyRead V20 is strictly an industrial automation tool. To provide a more tailored deep-dive, let me know:
Do you need the hardware requirements (cables, OS compatibility) for a setup?
Are you interested in the security implications and how to protect a PLC from such tools?
KeyRead V2.0 Mitsubishi is a software tool primarily used for unlocking and cracking passwords on older Mitsubishi PLC (Programmable Logic Controller) models, such as the FX1S, FX1N, and FX2N series. Key Feature: Password Cracking for Older PLCs
The primary feature of the software is its ability to bypass or recover "read/write" passwords from legacy Mitsubishi industrial hardware. keyread v20 mitsubishi
Supported Legacy Hardware: Specifically designed for the FX1S, FX1N, and FX2N models.
Restricted Support for Modern Models: While it works easily for older units, unlocking more modern series like the FX3U, FX3G, or FX3S often requires additional fees or specialized updates to the tool. Common Misconception
It is often confused with Mitsubishi automotive "Smart Keys" or the FAST-Key (Free-Hand Advanced Security Transmitter) system. However, the FAST-Key system is a vehicle entry feature that allows for keyless locking/unlocking and push-button start, which is entirely separate from the KeyRead software used in industrial automation.

The KeyRead V20 is a specific software version used by automotive locksmiths and technicians for programming transponder keys and remotes on Mitsubishi vehicles. It is typically a module within a larger diagnostic tool ecosystem (like those from Advanced Diagnostics) rather than a standalone device. 🛠️ Key Capabilities
The V20 update primarily focuses on enhancing the interaction between the tool and the vehicle's Immobilizer Control Unit (ICU).
Transponder Programming: Writes new ID codes to blank transponder chips for ignition startup.
Remote Synchronization: Pairs the keyless entry fob buttons with the vehicle's central locking system.
Pin Code Extraction: Automatically reads or calculates the "Security PIN" required by Mitsubishi to access programming menus.
All Keys Lost (AKL) Support: Allows technicians to generate new working keys even if no original key is present. 🚗 Model Compatibility
The V20 software version generally covers Mitsubishi models from the early 2000s through approximately 2020, depending on the specific region (US, EU, or Asia).
Common Models: Outlander, Lancer, Mirage, Pajero/Montero, and ASX.
System Types: Supports both traditional bladed keys and modern Smart/Proximity keys (Push-to-Start). 💡 Technical Insights
Mitsubishi programming often requires specific sequences to ensure success:
Slot Placement: For many 2019–2021 models, the "Smart Key" must be placed in a specific programming slot, often located inside the glove box or center console. [ ] The seller is an authorized distributor
Programming Sequence: On older models, DIY methods involving pressing the Lock and Unlock buttons simultaneously until lights flash may work, but newer V20-compatible systems usually require a hardwired connection to the OBD-II port.
Security Lockouts: If an incorrect PIN is entered multiple times, the vehicle may enter a "Lockout Mode," requiring a timed wait period before another attempt. ⚠️ Pro Tip
If you are attempting to use KeyRead V20 yourself, ensure your vehicle battery is on a stable power supply. Voltage drops during the "key writing" phase can corrupt the Immobilizer data, potentially bricking the ECU. Whether you have one working key or no keys at all? Are you using a specific device like the Smart Pro or TKO? Mitsubishi Key Fob Replacement and Programming
KeyRead V2.0 Mitsubishi is a specialized software utility used primarily by technicians and automation engineers to recover, crack, or unlock passwords on Mitsubishi Electric PLC (Programmable Logic Controller) hardware. Core Function: PLC Password Recovery
The primary feature of KeyRead V2.0 is its ability to bypass security restrictions on older generations of Mitsubishi PLCs, allowing users to access restricted ladder logic and program data. Supported Models and Capabilities
Legacy Series Support: The tool is highly effective for legacy "compact" PLC series, specifically the FX1S, FX1N, and FX2N models.
Password Retrieval: Unlike newer security protocols that may require hardware modification, this software typically reads the stored password directly via the serial (SC-09) or USB programming port.
Modern Limitations: While it can handle legacy devices freely, newer Mitsubishi PLCs like the FX3U, FX3G, and FX3S series often utilize more advanced encryption that standard versions of KeyRead cannot bypass without specialized updates or fees. Operational Requirements
Operating Systems: Designed for legacy Windows environments, including Windows XP, Windows Vista, and Windows 2000.
Hardware Interface: Requires a compatible programming cable (such as an SC-09 adapter) to establish a connection between the PC and the PLC's communication port.
Security Notice: Because the tool functions as a "crack" for industrial passwords, it is frequently flagged as malware or a potential threat by modern antivirus software.
In the rapidly evolving landscape of industrial automation, Mitsubishi Electric stands as a titan, powering everything from CNC machining centers to complex PLC-driven assembly lines. However, with increased connectivity comes a heightened need for security, version control, and operational transparency. Enter KeyRead V20—not merely a software utility, but a sophisticated hardware-key recognition and authorization framework. When integrated with Mitsubishi’s ecosystem (specifically the MELSEC iQ-R, iQ-F, and L series PLCs, as well as the M800/M80 CNC series), KeyRead V20 becomes the gatekeeper of your automated processes.
Prior to V20, performing an "All Keys Lost" procedure on a 2017 Mitsubishi Outlander required removing the glove box, unplugging the immobilizer module, and manually reading an eeprom (93C56). This was invasive and risky. Keyread V20 introduces a fully OBD2-based AKL solution for these models. As long as you have a working ignition or push-button start, the V20 brute-forces the vehicle's rolling code sequence in less than 3 minutes.
