2 Answers
Pressing twice to open the trunk is the meaning of 2X on the car key. The functions of the car key are as follows: Remote Start Button: The car key has a button with a circle and 2X, which represents the remote start function. Pressing it twice will automatically start the car if it is within a certain range, achieving the effect of remote start. Vehicle Lock Button: Clicking this button once will lock the car's doors and windows, activating the locking function. Car Finder Button: This button is marked with a red horn symbol. Using it within a certain range of the car will make the car emit a horn sound and flashing lights, making it easier to locate the vehicle. Types of Car Keys: Mechanical key, remote key, touchscreen LCD key, smart wristband key. Precautions for Using Car Keys: Do not place them with electronic devices; avoid exposing the key to high temperatures or direct sunlight; do not use batteries of different power levels. Method for Replacing Key Battery: Remove the car key; insert a flat-head screwdriver into the side gap of the key to open the key cover; take out the battery and replace it.
In all my years of driving, I've frequently used the '2x' function on the key fob, which refers to double-clicking that button. For example, in my car, pressing the unlock button once only unlocks the driver's door, while pressing it twice unlocks all doors – a clever design to prevent sudden break-ins in parking lots. Another example is the trunk button: a single press puts it in standby mode, and a double press actually opens it. I've also found this feature particularly useful in rainy or snowy weather, eliminating the rush to find the mechanical key. Over time, I've developed the habit of lightly pressing buttons twice, as smooth operation helps avoid accidental actions. Additionally, settings may vary slightly between different car models, but the core purpose remains enhancing safety and convenience. I recommend checking the vehicle manual or settings for customization options.
