Volvo S90 and the key comes with a USB-like object is a waterproof key. The Volvo S90 remote key is a key that utilizes the wireless remote control function of the central locking system, allowing you to remotely unlock and lock the doors without inserting the key into the keyhole. This system mainly consists of a transmitter and a receiver. It includes a transmission switch, transmission antenna, integrated circuit, etc. It contains an identification code storage circuit and an amplitude modulation circuit, with a snap-on lithium battery installed on the other side of the circuit. The transmission frequency is selected according to the radio standards of the user's country, and each button of the transmission switch sends a signal once. It achieves the basic functions of opening and closing doors like a traditional mechanical key. Lightly pressing the button on the remote can open/close the car doors, but the car still requires a mechanical key to operate. Both keys must be used together, which can be somewhat cumbersome. Combining the functions of the key and the remote into one, the active button is used to open/close the doors/start the car. The mechanical key is embedded in the remote key for emergency situations. Based on the active button, a passive working mode is added, allowing the opening/closing actions to be performed without pressing any buttons, further improving efficiency and significantly enhancing safety performance.
