The Autel XP400 PRO is a key and immobilizer programmer that works as an add-on to Autel's IM508 and IM608 tablets, not as a standalone tool. It reads and writes EEPROM, engine ECU, MCU and immobilizer chips, with coverage of 440+ EEPROM, 40+ engine ECU, 2000+ MCU and 180+ immobilizer ECU types. It adds extended BMW, Mercedes-Benz and Audi IMMO functions and fixes the burnout problem of the original XP400. At $335.00 at Best Key Supply as of November 5, 2026, it sits at the low end of its recent range across the three stores that list it new.
