Cadillac XT5 key fob function explanation: Press the lock button (round button), then hold it down to remotely start the vehicle. First press the lock button once, then hold the remote start button to start the car. This ensures that the vehicle can only be remotely started when it is locked, enhancing security. However, this function must first be enabled in the central control interface before the key fob can start the vehicle. 2. The remote key utilizes the wireless remote control function of the central locking system, allowing doors to be unlocked or locked from a distance without inserting the key into the lock. The key fob combines the functions of a traditional key and a remote, enabling locking/unlocking and starting the car via active buttons. A mechanical key is embedded within the remote key for emergencies. In addition to active button operation, passive operation is also supported, allowing doors to be unlocked/locked without pressing any buttons, further improving efficiency and significantly enhancing security.
