The Autel MaxiIM IM508S is a professional key and immobilizer programming tablet for working locksmiths and shops. It adds all-system diagnostics and 28+ maintenance services to key fob programming, and it ships with the XP200 key programmer. It is the upgraded IM508: a quad-core Rockchip RK3566 processor, 4GB RAM and 64GB storage, Android 11 and dual-band Wi-Fi make it faster than the older model. In North America it needs an active NASTF SDRM subscription, bought separately, before key programming works. That requirement and its price class put it against the Autel KM100 and the higher-end IM608; it suits buyers who program keys regularly, not occasional DIY use.

The Autel MaxiIM IM508S is a key and immobilizer programming tool with full-system diagnostics. It comes with the XP200 key programmer. Together they handle key and remote learning and basic EEPROM and MCU read and write.
For immobilizer work, it can reset or adapt the IMMO ECU, refresh or code it, read the PIN/CS (all keys lost), generate keys, and learn keys and remotes. Smart Mode gives step-by-step guidance. Expert Mode lets you run each function on its own. The IMMO application needs a data link to the vehicle's immobilizer control system through the OBD II connection.
For diagnostics, it reads and clears DTCs on all available modules of most current makes and models. It also runs bi-directional active tests that send commands to the vehicle's ECU to drive actuators. Special functions include Oil Reset, EPB, SAS, BMS, DPF and ABS Bleed.
