Autel XP400 Pro: All-in-One Key Programmer for Auto Technicians

As vehicles become more advanced, so too must the tools used to service them. The Autel XP400 Pro is a high-performance key and chip programmer designed for professional locksmiths and automotive technicians who require robust, reliable, and cutting-edge key programming capabilities.

Paired with Autel’s IM-series diagnostic tablets like the IM508S, IM608, and IM608 Pro II, the XP400 Pro enhances the ability to perform complex key programming and chip-level diagnostics across a wide range of vehicles.

What is the XP400 Pro?

The XP400 Pro is not just a key programmer—it's a comprehensive ECU and chip-level diagnostic assistant. With capabilities that go far beyond basic transponder functions, this tool allows technicians to read and write EEPROM and MCU/ECU data, generate smart keys, clone transponders, and even perform ECU coding in supported systems.

When paired with an IM608 Pro II, the XP400 Pro transforms the tablet into an OE-level immobilizer and key programming workstation, capable of handling some of the most complex anti-theft systems on the market—including systems found in Mercedes-Benz, BMW, Volkswagen/Audi Group, and others.
