What Are the Hidden Functions of Car Keys?

[MacWillow]

Here are the detailed introductions to the hidden functions of car keys: 1. Close windows after turning off the engine: Press and hold the lock button on the remote key to close the windows. This feature may also be available on ordinary family cars. 2. Find the car in a parking lot: Some car keys have a dedicated car-finding button. For certain vehicles, pressing the lock button twice in succession will make the car emit a very loud honking sound to indicate its location, making it easier to quickly find the car in crowded parking areas. 3. Automatically open the trunk: Many car models have a trunk-opening button on the remote key. Press and hold the trunk unlock button to automatically open the trunk. 4. Child safety lock: Mostly located on the rear doors, it requires a mechanical key to lock.
