What do the function buttons on the Song Plus car key mean?

The function buttons on the Song Plus car key are conventional functions for locking, unlocking, and opening/closing the trunk. Conventional functions: The Song Pro car key has a button with a vehicle pattern. Pressing it twice in succession will open the trunk door, and pressing it twice again will close the trunk door. This design prevents accidental opening of the trunk door, improving safety to some extent. Hidden function: The hidden function is auto window roll-up upon locking. First, with the vehicle powered on, roll all four windows up to the highest point, then hold the lock button for more than 10 seconds. This will successfully activate the auto window roll-up function when locking. When the windows are not fully raised, the owner can press the lock button on the car key after getting out of the vehicle, and the windows will automatically roll up while the car locks.
I've been driving the BYD Song Plus for a while, and its key design is quite user-friendly. The main button has a lock icon—a short press locks the doors, while a long press automatically closes the windows to prevent rainwater leakage. The unlock button features an unlock icon; a single click opens only the driver's door, while a double-click unlocks the entire vehicle, enhancing security by preventing strangers from rushing in. There's also a button with a rear car pattern—holding it for 2 seconds opens the trunk, which is very convenient when parking for shopping. Another button with a horn icon triggers the lights to flash and the horn to beep with a single press, making it easy to locate the car in a parking lot. At the bottom of the key, there's a small groove where a mechanical key can be pulled out for emergency use if the battery dies, allowing access to the driver's door. I frequently use these features, especially the car-finder button in supermarket parking lots—it saves me from wandering around searching for my car. Regularly replacing the battery ensures responsiveness, so don't wait until it's dead to act.
As a car owner, I find the buttons on the Song Plus key fob quite practical. The circular lock button: press once to lock the doors, double press to activate the anti-theft system. The unlock button opens all doors with two quick presses, saving effort. The trunk button: hold it down to directly open the hatchback, making loading luggage easy. The special 'i' letter button activates the quick-response vehicle finder function with a single press, great for locating your car at night. Best of all is the remote start button, which lets you warm up the car for a few minutes in cold weather before getting in. The mechanical key hidden on the side is used for manual unlocking when the battery runs low - a common issue. I recommend replacing the CR2032 battery every two years to maintain responsiveness. Avoid exposing the fob to water or high temperatures to prevent button failure. These small designs significantly enhance daily driving convenience.
