Car Battery Dead and Can't Unlock the Door with Key?

For foldable keys, you can unfold the key and use it to unlock the door. Smart keys usually have a key head inside; you just need to find the place to open it. Precautions for using remote keys are as follows: 1. Do not place the key together with electronic devices like mobile phones or computers. 2. Do not throw the key around. The circuit board inside the key is relatively fragile, and prolonged rough handling can easily damage it. 3. If the key gets wet, do not shake it or press any buttons. Open the key casing and use a hairdryer to dry it; otherwise, water may spread across the entire circuit board. 4. Try to avoid using metal key covers. Metal materials can partially block the signal of the smart key. 5. Smart keys are sensitive to high temperatures and direct sunlight. Please do not place the smart key on the dashboard. As a product made of chips, plastic, and metal, exposure to high temperatures and direct sunlight will accelerate the aging of the smart key.
When I first bought my car, I also encountered a situation where the car had no power and couldn't open the door. I was so anxious. Later, I figured out that most key fobs actually have a hidden mechanical key as a backup solution. Flip your remote key over and carefully look for a small button or latch on the side. Press it firmly, and you can pull out a thin metal key blade. Then, locate the inconspicuous small square cover behind the door handle and gently pry it open with the tip of the key to reveal the keyhole. Last time, I was stuck in a parking lot late at night and solved the problem this way—the whole process took just five minutes. But opening the door isn't the end of it; remember to check the battery condition immediately or get a jump-start from another car. If you delay too long and the entire car loses power, you won't even be able to close the windows, which would be troublesome. It's best to develop a habit of keeping the mechanical key separately in your wallet for emergencies, saving you the hassle when unexpected situations arise.
