What to Do When the Car Key Fails to Start the Engine?
2 Answers
The methods to handle a car key that fails to start the engine are: 1. Press the button on the side of the key to remove the mechanical key; 2. Insert the key into the door handle of the driver's side and open the door; 3. Place the car key near the lower right corner of the steering wheel and press the start button. Car keys are categorized into: 1. Traditional mechanical keys that enable the opening and closing of the car door; 2. Remote control keys that allow the door to be opened or closed with a light press of a button; 3. Keys that combine both the key and remote control functions, enabling the opening and closing of the door through active button pressing; 4. Keys that, in addition to active button pressing, incorporate a passive working mode, allowing the door to be opened or closed without pressing any buttons.
I just experienced this last month! My first thought was to check if the button battery in the remote key was dead. At that time, my car didn't respond at all, and even the dashboard didn't light up. Later, I tried using the mechanical key to open the door lock, only to find the steering wheel was locked. After struggling for a while, I remembered that with older cars, sometimes you need to turn the key while simultaneously turning the steering wheel left and right to unlock it. If that doesn't work, try using an emergency power source to jump-start the car—it might be that the car battery is drained. Another easily overlooked issue is signal interference in the induction area, such as keeping your phone and key in the same pocket, which can disrupt the signal. The safest option is still to call for roadside assistance; professional equipment can detect fault codes faster and more accurately.
