The Mercedes me app by Mercedes-Benz can indeed track the vehicle's location, but it should be clarified that this function primarily targets the vehicle itself rather than the physical location of the car key. Through the app, car owners can view the precise real-time location of their Mercedes-Benz vehicles equipped with a GPS system on a map, and it supports operations such as remote locking and air conditioning activation. For locating the original factory key, the standard remote key does not have a built-in GPS module, but users can install third-party positioning devices on their own to enable tracking. Regarding key management, if the digital key function is enabled (e.g., some models support mobile phone Bluetooth keys), the key status can be indirectly monitored through the mobile phone, such as safety reminders like vehicle departure alerts. Overall, Mercedes-Benz's smart connectivity technology centers on the vehicle, and key positioning is an extended requirement that needs to be achieved through specific configurations or additional solutions.
