Description
AUTEL • Key and chip programmer XP400 PRO
The AUTEL XP400 PRO is an advanced key and chip programmer designed for professional locksmiths and vehicle security technicians. Compatible with Autel’s IM508 and IM608 tablet platforms, it reads, writes, and generates keys—including infrared smart keys for Mercedes and IC chip keys for Hyundai/Gia models. It performs over 3,000 chip-type read/write operations (including EEPROM, MCU, engine and immobilizer ECUs), and adds odometer, remote frequency detection, and extended OEM-level IMMO functions for European vehicles. Built materials include durable ports, key and transponder slots, and upgraded components designed to eliminate the burnout issues reported on earlier versions.
