1 Answers
The solution for a car key that is hard to insert is: crush pencil lead and apply it to the keyhole. The steps are: 1. Use a knife to scrape the pencil lead into powder; 2. Put the powdered pencil lead into a plastic tube and blow it into the keyhole; 3. Repeat the above steps until the car key can be inserted and removed smoothly. The working principle of a car key is: it emits a weak radio wave from the owner, which is received by the car antenna. After the electronic controller identifies the signal code, the system's actuator performs the action of unlocking or locking. The functions of a car key include: 1. Remote locking and unlocking; 2. Long-press the lock button after turning off the engine to close the windows; 3. Press the horn-shaped button to locate the car.
