Support varies by firmware version, adapter set, and region. Commonly targeted Mitsubishi systems include:
To justify the keyword "best," let's compare the V20 against its top rivals specifically for Mitsubishi applications.
| Feature | KeyRead V20 | Autel IM608 | Xtool X100 PAD2 | Lonsdor K518 | | :--- | :--- | :--- | :--- | :--- | | Mitsubishi All-Keys-Lost (2016+) | Excellent (Direct Read) | Fair (Needs token) | Poor (Fails often) | Good (Slow) | | Smart Key Programming | Full Function | Partial (J2534 required) | Not Supported | Full Function | | G-Lock Bypass (2020+) | Yes | No (Needs server) | No | Yes (But slower) | | Price Point | Mid-Range | High-End | Mid-Range | High-End | | Mitsubishi Specific Database | Dedicated Module | Generic | Generic | Dedicated |
Conclusion: While the Autel IM608 is a better general scanner, it is not the best Mitsubishi tool. The KeyRead V20 is hyper-specialized. It wins on speed, reliability, and cost-per-job.
If you work on Mitsubishis daily, the Keyread V20 Best pays for itself in a few jobs. For the price (under $400–500 depending on source), it’s one of the most cost-effective dedicated programmers out there. Just keep a backup tool for the newest models.
Would I buy again? Yes.
Recommended? Absolutely – for Mitsubishi-focused work.
While there is no official "Keyread V20" product in the Mitsubishi Electric or Mitsubishi Motors official product lineups, technical users often use this term to refer to advanced diagnostic readers or key programming interfaces compatible with Mitsubishi's V20 software protocols. These tools are essential for managing modern vehicle entry systems or industrial automation controllers. Core Capabilities of V20-Compatible Readers
Diagnostic and "key-reading" tools optimized for Mitsubishi systems typically focus on two distinct areas: automotive security and industrial communication.
Automotive Key & ECU Access: For vehicle owners and locksmiths, these interfaces allow interaction with the Mitsubishi Fast Key Entry system. They can read immobilizer data, assist in programming spare smart keys, and troubleshoot "Twist Proximity" or "Start/Stop" button systems.
Industrial Data Transmission: In the industrial sector, instructions like TRD (Table Read) are used within Mitsubishi PLCs (Programmable Logic Controllers) to read data from I/O modules and special registers.
Error Code Diagnostics: High-quality readers can access unique fault codes displayed on units, which is critical for identifying specific mechanical or electronic issues in Mitsubishi Ductless Mini Splits and other HVAC systems. Choosing the Best Diagnostic Interface
The "best" reader for Mitsubishi systems is defined by its ability to handle complex programming tasks without damaging the hardware.
Software Compatibility: Ensure the tool supports the latest version of GX Developer or relevant PLC development software like GX Works2. keyread v20 mitsubishi best
Hardware Stability: For industrial setups, the hardware must adhere to strict safety standards, including proper grounding and voltage ratings to prevent malfunctions.
Broad Range Support: The most versatile tools can handle a wide range of codes; for instance, some universal controllers must be manually scanned through a large range (e.g., code 551 and above) to find the perfect match for a specific Mitsubishi AC unit. Safe Programming Practices
When using any reading or programming tool, following official manuals is vital to avoid property damage or injury.

"KeyRead V2.0" for Mitsubishi is a specialized software tool used primarily for industrial automation. It is designed to unlock or "crack" passwords on Mitsubishi Electric Programmable Logic Controllers (PLCs), specifically from the MELSEC iQ-F (FX) series. Core Functionality
The software is most commonly used by technicians who need to access a PLC when the original password has been lost or was not provided by the installer. Key features include:
Password Retrieval: It reads the internal password levels directly from the PLC hardware.
Supported Models: It is optimized for the FX3U and FX3G series, but older models like FX1S, FX2N, and FX1N are also frequently supported by related versions of the tool.
Backup & Recovery: It allows users to backup programs from locked PLCs to ensure a machine can be repaired or its hardware upgraded if it fails. Why It's Used
Automotive and industrial professionals use KeyRead V2.0 for several critical maintenance tasks:
Recovering Lost Data: If a PLC's program hasn't been backed up and the password is lost, this tool is one of the few ways to retrieve the logic.
System Upgrades: Necessary for migrating old PLC programs to newer hardware when the original source code is password-protected. Support varies by firmware version, adapter set, and region
Emergency Repairs: Fast-tracking the diagnostic process for machines that are down but have restricted software access. Technical Availability
While some sites offer demo versions for testing, full versions of the software are often sold through specialty automation and "unlock" service providers like CrackPLC.
Note: If you were looking for information on programming a Mitsubishi car key fob, this is a different manual process. Most fobs can be synced by holding the lock and unlock buttons until the lights flash three times, then pressing the unlock button until they flash twice.
Are you using this for a specific PLC model (like the FX3U) or Mitsubishi Key Fob Replacement and Programming
To achieve the "best" results, you must match the V20 configuration to the vehicle generation. Below is the optimized matrix.
If you are using a diagnostic tool with a "Keyread v20" equivalent function, here is the standard workflow for programming a key:
Yes. If your primary or secondary market is Mitsubishi vehicles, the KeyRead V20 is arguably the best investment you can make under $800.
While the V20 is not a universal monster like the Autel or Smart Pro, it is a specialized sniper rifle for Mitsubishi’s security systems. It offers:
Final Recommendation: Purchase the KeyRead V20 Master Kit with the Mitsubishi Crypto Upgrade. Download the latest v2.1.5 software. Stock up on JMD5 Super Chips. You will never turn down a Mitsubishi "All Keys Lost" job again.
Disclaimer: Always verify compatibility with your specific V20 hardware revision. KeyRead is a trademark of its respective manufacturer. This article is an independent guide for professional locksmiths.
In the world of industrial automation, "KeyRead v2.0" (often referred to as KeyReader) is a specialized tool used by technicians to unlock or crack passwords on Mitsubishi PLC (Programmable Logic Controller) hardware.
Here is a story of how a technician might use it to save a production line. The Midnight Reset: A Story of KeyRead v2.0 While there is no official "Keyread V20" product
The humming of the assembly line at the automotive plant usually sounds like money being made, but at 2:00 AM on a Tuesday, the silence was deafening.
The CrisisA critical Mitsubishi FX2N PLC—the "brain" of the conveyor system—had faulted after a power surge. Leo, the night-shift lead technician, stared at the screen of his laptop. He needed to upload the program to see why the logic was stuck, but a "Password Protected" prompt blocked him. The former plant manager, who set the password years ago, was long gone, and the documentation was missing.
The SolutionLeo reached into his toolkit and pulled out a small USB drive containing KeyRead v2.0. This software was designed for exactly this scenario: recovering access to legacy Mitsubishi PLCs like the FX1S, FX1N, and FX2N series when passwords are lost. The Process
Connection: Leo connected his laptop to the PLC’s programming port using an SC-09 cable.
Interface: He launched the KeyRead v2.0 utility. The interface was simple, focusing on the specific registers where the password data was stored.
The Read: He clicked "Read." For a few tense seconds, the software communicated with the PLC, bypassing the standard user interface to read the internal memory.
Success: A series of four characters appeared on the screen.
The ResultLeo typed the characters into his GX Developer software. The lock icon vanished. He quickly identified a corrupted timer value caused by the surge, reset it, and pushed the update. Ten minutes later, the conveyor belt lurched back to life.
While newer Mitsubishi models like the FX3U or FX3G often require more advanced (and sometimes paid) methods to unlock, KeyRead v2.0 remains the "best" tool for technicians dealing with older, reliable hardware that keeps the world’s factories moving.
However, there is no widely known automotive diagnostic tool or key programming device under that exact name in major databases (e.g., from Autel, Launch, Xtool, or original Mitsubishi MUT-III).
The closest possibilities are:
While it might be the "best" for older cars, it has significant limitations compared to modern universal key programmers:
