: Unauthorized logic extraction may violate intellectual property agreements with original equipment manufacturers (OEMs). Always verify ownership before executing recovery software.
: Standard Mitsubishi programming software (GX Developer or GX Works) requires clearing the memory block to bypass an unknown password. KeyRead extracts the key while preserving the ladder logic.
Using non-genuine or "clone" Keyread V20 units on a Mitsubishi CAN system often results in "Immobilizer Malfunction" errors (DTC B2100), requiring dealership intervention to resolve. keyread v20 mitsubishi

Locksmith technology evolves rapidly. Automotive security demands advanced, reliable tools. The standalone software and hardware package stands out as a premier solution for professional locksmiths and diagnostic technicians.
While KeyRead V2.0 is an indispensable asset for plant maintenance departments working on older machinery, its existence highlights structural vulnerabilities in legacy automation frameworks.
The application operates by directly querying the PLC’s internal EEPROM or flash memory tables where keywords (passwords) are temporarily cross-referenced during a programming login handshake. : Standard Mitsubishi programming software (GX Developer or
Securely attach the SC-09 serial cable between the PLC's round 8-pin mini-DIN programming port and your laptop's serial/USB port.
The application will process for a few seconds and display the active keyword in plain text within the application window.
Once the system password is recovered, engineers should transition the underlying ladder logic over to modern, secure controllers with robust cryptographic protection.
