What's New in Key Tool Max Pro?
Newly Added OBD Module
The KEY TOOL MAX and MINI OBD TOOL were once a powerful combination, allowing users to complete various tasks via wireless connection. With the MAX PRO, an OBD cable is now included, enabling direct connection to the vehicle’s OBDⅡ port. This eliminates the need to purchase a separate MINI OBD TOOL for immobilizer programming and other functions. Additionally, a wired connection provides greater security and reliability with minimal risk.
Built-in CAN_FD Module, Expanded Function
For immobilizer programming, the MAX PRO features a built-in CAN_FD module, enabling it to program a wide range of CAN_FD vehicles, including models like Cadillac CT4/CT5 and Buick GL8, Encore, and more. Xhorse provides free, continuous software updates, ensuring that support for additional car models keeps expanding for maximum convenience.
Battery Test Module
Combining the needs of automotive locksmiths with our innovations, KEY TOOL MAX PRO features a new battery test module. By simply connecting to the leakage detection cable, users can test whether a remote battery is having electric leakage (range: 1μA~35μA) and detect the voltage of a remote battery (range: 0V~36V).
NEW - BMW CAS3/Toyota Models Programming
To make it a more powerful and competitive tool, KEY TOOL MAX PRO is projected to add the programming feature of BMW CAS3 and some Toyota models soon. As always, Xhorse provides continuous software upgrades for this cutting-edge device, with more features and vehicle support expected in the future.
