Autel MaxiIM IM508S vs Lonsdor K518 PRO Key Programmer

Both are Android key programming tablets for locksmiths and technicians, and both cover immobilizer work on most US and Asian cars. The Autel IM508S is the more polished all-rounder: newer Android 11, 4GB RAM, a bundled XP200 programmer, and 28+ service functions alongside diagnostics. The Lonsdor K518 PRO Full Version counters with broader coverage claims, CANFD and DoIP support, 8A(H) chip generation, 24V truck support, and Bluetooth. Owners of both report they work as advertised for common keys; the deciding factor is whether you need diagnostics plus service functions (Autel) or the widest immobilizer and chip coverage (Lonsdor).

• Choose the Autel IM508S if you want one tablet that does key programming plus full-system diagnostics and 28+ service resets, with newer hardware and the XP200 included.
• Choose the Lonsdor K518 PRO if immobilizer and chip work is your main job and you need CANFD, DoIP, 8A(H) chip generation and 24V truck support.
