Car key, unlike door key, besides open door outside this foundation function, return the function of science and technology that can increase produce the expected result of main body of car of a few promotion.
Grow the Che Jian that press a lock for instance, car window can be closed after flameout. Should say this function is too practical. For instance your car window did not close severe, and right now a cloudburst already came, so, you can grow the Che Jian that press a lock, remote control closes car window below eave.
Opposite, if think remote control drives window, can try long press Suo Jian, partial model has this function.
Some car keys have the button that find a vehicle, also having car is to lock up Che Jian to press continuously, car can cry flute and double shine indicate the position. This searchs car function namely. But the only car that press a lock also is met flashlight, cry flute, so I feel this function it doesn't matter can say.
Still have for instance mothball compartment key-press, can open mothball box by two, this is commonner also.
