Autel G‑Box 3 Mercedes All‑Key‑Lost & BMW ISN Adapter

The Autel G-BOX3 is a dedicated programming adapter compatible with the Autel MaxiIM IM608 and MaxiIM IM508 tablets, used in conjunction with the XP400 Pro programmer. It is designed to assist with key programming on Mercedes-Benz DAS3 CAN EIS/EXS vehicles in all-keys-lost scenarios, and supports DME/DDE ISN reading and writing in Boot Mode on compatible BMW vehicles. Bench method programming is also supported. All-keys-lost password calculations are performed approximately 4 to 8 times faster than standard methods.

Autel G‑Box 3 Specification

Autel G-Box3 VS Autel G-Box2

The two adapters are very similar in function — both handle Mercedes-Benz All Keys Lost and BMW DME/DDE ISN work. The main differences are:

1. IM508 programmer requirement — G-Box 2 pairs with the XP400, while G-Box 3 requires the newer XP400 Pro.
2. Repeated EIS insertions — G-Box 2 eliminates this only for W216 and W164 models from 2009 onwards, while G-Box 3 extends this improvement across all supported models.
3. Generation — G-Box 3 is the newer release and is better positioned for customers already using or upgrading to the XP400 Pro.
