The Autel MaxiIM IM508S Pro is a tablet-based key and immobilizer programming tool with the XP400 Pro programmer included. It also does all-system diagnostics and 40+ maintenance services, so it covers both key work and everyday shop diagnostics. The S Pro upgrade brings a faster Rockchip RK3566 processor, 4GB RAM, 64GB storage, Android 11 and dual-band Wi-Fi over the older IM508. It suits locksmiths and independent shops that program keys across many brands; it is not a tool for casual DIY owners.
