The XTOOL X100 Max is a professional wireless bidirectional scan tool that combines OE-level diagnostics, ECU coding and topology mapping with key and chip programming through the bundled KC501, KS-1, SK1 and M822 accessories. It covers 42+ reset functions and reads and writes MCU/EEPROM chips, remote frequencies and chip IDs, with key matching for VW/Audi/Skoda 4th, 5th and MQB, BMW CAS1-CAS3++ and Land Rover smart keys after 2015. It suits repair shops, locksmiths and advanced DIY users who need diagnostics and key work in one tablet. Against cheaper bidirectional scanners it adds real key programming; against dedicated key tools it adds full diagnostics, but it is a bigger investment and has a learning curve.

The XTOOL X100 MAX is a wireless, bidirectional automotive diagnostic and ECU programming tool with key programming accessories. It runs OE-level diagnostics on available vehicle systems, including ABS, SRS, TPMS, engine, transmission and brakes. It provides full codes, real-time data, active tests and ECU information.
Active testing lets the tool send commands to the ECU to request information or run specific tests. It also supports ECU coding, component matching, adaptive data reset and activating or disabling vehicle features, such as the seatbelt buzzer. A topology map shows how vehicle systems connect. Live data can be graphed, recorded and played back for analysis.
The set includes the KS-1, SK1 and M822 key programming accessories. The KS-1 and SK1 work with an XTOOL tablet plus a KC100 or KC501 key programmer. The KS-1 handles all-keys-lost matching for Toyota and Lexus without disassembly. The SK1 is a data collector and smart key emulator for key cloning on 2013 and newer Toyota smart key models. The M822 adapter supports Toyota 8A all-keys-lost programming.
