In the world of automotive diagnostics and key programming, the Autel IM508S with XP400 Pro and Xhorse Key Tool Plus are two popular choices often compared by technicians and locksmiths.
Autel IM508S with XP400 Pro is not just a key programmer — it’s a full professional diagnostic tool. It scans all vehicle systems (engine, transmission, ABS, airbags, BCM), reads/clears fault codes, displays live data, performs active tests (like commanding fuel pumps or fans), and includes over 28 service functions (oil reset, EPB, SAS calibration, etc.). When paired with the XP400 Pro accessory, it delivers strong key programming coverage across American, Asian, and European vehicles, with guided steps ideal for beginners. It’s perfect for general repair workshops that do both diagnostics and occasional key work.
Xhorse Key Tool Plus (often called VVDI Key Tool Plus) is a dedicated locksmith-focused device. It excels in key programming, especially for European brands like Mercedes (fast password calculations), BMW (CAS/FEM systems), and VAG (MQB platforms with less dashboard removal). It has a built-in chip reader, frequency tester, and large 10-inch screen, plus an open ecosystem for generating cheaper universal remotes with high profit margins. However, its diagnostic capabilities are basic — it can’t handle deep repairs like misfires or complex sensor issues.
Key Differences
1. Choose Autel IM508S with XP400 Pro if you run a general workshop needing strong diagnostics plus reliable key programming — one tool covers multiple income sources.
2. Choose Xhorse Key Tool Plus PAD if you’re a full-time locksmith focused on European vehicles, speed, and cheaper universal keys (especially if you already own a separate diagnostic scanner).
