Can Car Keys Be Controlled by a Mobile Phone?

[PhoebeLee]

This requires the vehicle's 4S dealership to perform a matching interaction between the vehicle and the driver's mobile phone; otherwise, remote control of the vehicle via the phone cannot be achieved. Below is relevant information about car keys: 1. Number of Keys: Vehicles typically come with 2-3 keys. When a new car is handed over to the owner, the salesperson usually reminds the owner to keep the keys safe. 2. Key Code: The key set for a new car consists of 2-3 keys and a metal or plastic tag. On this tag, there is usually a series of numbers, which is the key code. Service centers or manufacturers can use this code to reconfigure keys for the owner.
