The XP400 Pro is a powerful key and chip programmer designed to work seamlessly with the Autel IM508 and IM608 tablets. It handles full read, write, and key learning functions for the vehicle, giving locksmiths and auto professionals an advanced tool for tackling complex immobilizer work.
The XP400 Pro supports infrared key programming for Mercedes-Benz vehicles, as well as IC chip key programming on late-model Hyundai and Kia vehicles. It also performs the EEPROM data functions commonly required when servicing European makes.
With support for read and write operations across more than 3,000 chip types — including EEPROM, engine ECU, MCU, and IMMO ECU — the XP400 Pro delivers the versatility needed for both routine key jobs and advanced programming scenarios.

Autel XP400 & Autel XP200 Diagrams
This KeyAxis Inc. comparison chart provides a side-by-side breakdown of three Autel key programming and IMMO bundles — the XP200+IM508, XP400+IM508, and XP400+IM608 — helping locksmiths and automotive technicians choose the right kit based on supported IMMO and programming functions. The chart uses three indicators: a black square for supported functions, an X for unsupported functions, and a blue square for newly added functions.
