What Are the Hidden Functions of Car Keys?
1 Answers
In addition to the daily use of locking and unlocking the vehicle, car keys also have some hidden functions, mainly in five scenarios: 1. Window closing function after turning off the engine. For drivers who have already exited the vehicle, pressing or holding the lock button can automatically close the windows. 2. Automatic trunk opening. Many keys have a trunk button; pressing and holding or double-clicking the trunk unlock button can automatically open the trunk. 3. Remote window opening. 4. Opening a single door. Pressing the unlock button can open only the driver's door, while other doors remain locked. 5. The small piece of paper on the car key. This serves as proof for key replacement in case the key is lost.
