X100 MAX Key Features

Best Choice for Locksmiths

If you need a reliable, high-performance key programming tool that “can work, work much, work fast,” the XTOOL X100 MAX is an excellent choice. Compared to the entry-level X100 PAD3 and IM608, the enhanced KC501 module enables advanced IMMO support for brands like Mercedes-Benz, BMW, and Volkswagen—including KS01 and SK1 systems. It excels at Toyota all-key-lost scenarios and delivers up to 3× faster performance for tasks like IMMO/EEPROM/MCU read/write, key add/delete/learn, and more.

Comprehensive IMMO & Key Programming Capabilities

• Generate dealer keys
• Add new keys
• Program new key fobs
• Key learning
• Remote learning
• Read remote frequency, chip type, and chip ID
• Key chip read & write
• EEPROM read & write
• Transponder read & write
• Basic MCU read & write

• Volkswagen/Audi/Skoda/Seat IMMO III/IV/V key addition and all-key-lost recovery

Topology Module Mapping

The X100 MAX scans all available vehicle modules and displays their diagnostic status in a color-coded tree map, revealing inter-module communication structures to significantly improve workshop repair efficiency.

Advanced ECU Coding

Unlock hidden features, disable annoying functions, enhance vehicle performance, customize OEM settings, reprogram adaptive data after component replacement, and configure high-end models—all to improve fuel efficiency and ensure safe driving.

Bi-Directional Control

This bi-directional tool sends commands to ECUs, reads ECU data, and monitors actuator operation through active tests to precisely identify faults. For example, if a fuel pump failure causes ignition issues, you can toggle the pump via the X100 MAX to quickly isolate whether the problem lies in the pump, wiring, relay, or control signal—without disassembly.
Note: Available functions vary by vehicle.

OE-Level Full Diagnostics

Read all DTC types across full vehicle systems—including ABS, SRS, TPMS, engine, Transmission, and Brake System—view and graph live PIDs, record data for playback, and perform actuation tests. AutoVIN enables rapid vehicle identification for fast diagnostics. This comprehensive scan process efficiently locates faulty systems and retrieves relevant DTCs, allowing you to optimize performance, save energy, and reduce emissions.
