Description
AUTEL • Key matching adapter MaxiIM G-BOX3
The AUTEL MaxiIM G-BOX3 is an accessory adapter designed for professionals using Autel’s IM608 or IM508 diagnostic tablets (with the XP400Pro programmer) to handle advanced key programming tasks. It enables faster and more secure All Keys Lost (AKL) service for Mercedes-Benz DAS3 CAN EIS/EZS systems, and supports reading and writing ISN data on select BMW DME/DDE control modules. Its build includes comprehensive connections—CAN, K-line, OBDII, DB15, fuse, relay, and 12 V power ports—to suit both on-vehicle and bench workflows with Bosch EDC17/MED17, MD1/MG1, and other ECUs.
