Car keys can be replaced. Below are the functions of car keys: Closing windows after turning off the engine: Press and hold the lock button on the remote key to close the windows. Some ordinary family cars may also be equipped with this function. Finding the car in a parking lot: Some car keys have a dedicated car-finding button. For certain vehicles, pressing the lock button twice will make the car emit a beeping sound to indicate its location, making it easier to find the car quickly in crowded parking areas. Automatically opening the trunk: Many car models have a trunk-opening button on the remote key. Press and hold the trunk unlock button, and the trunk will open automatically. Keyless entry: You need to carry the car key. When the key is near the car, it will automatically match the car's decoder. Press the unlock button on the car door handle to unlock the car.
