Car keyless start system means starting the vehicle without taking out or turning a physical key. The key can be kept in a bag or pocket, and the engine can be ignited by pressing a button inside the car or turning a knob. Below is more information about the keyless start system: 1. Types of keyless start: Button type: The ignition button is located within easy reach on the center console, hence also known as "one-button start," such as in BMW and Mercedes-Benz; Knob type: Generally located at the original key slot, but without the need to insert the car key, simply turning the knob can start the engine, such as in Nissan and Mazda. 2. Opening and closing doors: Normally, when the key is within an effective detection distance of about 1.5 meters from the main door, the ID of the key chip will automatically match with the engine's ID. After successful pairing, the car door will open without the need for a key. When the driver leaves the vehicle, the door locks will automatically engage and enter an anti-theft state. However, if the smart key runs out of battery, there is a sensor button on the vehicle's door handle, as well as a keyhole, for use in case the smart card is damaged or out of power. 3. Starting and stopping the vehicle: When entering the car, the vehicle's detection system will immediately recognize the smart card. After confirmation, the car's computer will enter a working state, and then simply pressing the one-button start button (or knob) inside the car can normally start the vehicle. Similarly, when the vehicle needs to be parked and turned off, just press the one-button start button (or knob) after the car comes to a complete stop to shut down the engine.
The keyless start system is one of my favorite car features, especially practical when rushing to work every day. In the past, I had to dig through my bag for the key before driving, but now just carrying the key near the car door and pulling the handle automatically unlocks it. Once inside, stepping on the brake and pressing the button with a lightning symbol on the center console makes the engine roar to life. This system relies on a small chip in the car key and sensors in the car body confirming each other's signals. The most convenient part is not having to free up a hand to take out the key when opening the door or starting the car, especially in winter when holding a coffee cup. However, my wife once left the key in the trunk, and the car automatically locked, requiring us to find the spare key to open it—something to remind everyone to be careful about.
