How to Start the Car Without a Key?

When the key is near the main door, the ID of the key chip automatically matches the ID of the engine. After successful pairing, the car door will open. The detection system inside the car will immediately recognize the smart card. Simply press the one-button start button (or knob) inside the car to start the vehicle normally.
I'm really into researching little car tricks, especially those designs that allow starting without a key. Many cars nowadays come with keyless start functionality—just keep the key on you, approach the car's sensing area, press a button, and the engine roars to life. Many brands like Toyota and Honda have this as standard, while more premium ones like BMW and Mercedes even offer remote engine start via a mobile app, which is super convenient. I remember the last time I drove my friend's Tesla—I unlocked and started it directly with my phone without even taking out the key. However, some older cars require modifications to use this feature, but the upgrades aren’t too expensive; I’d recommend asking a professional auto shop. Also, in the future, we might see fingerprint or facial recognition for starting cars, but the current technology is already quite mature with high security, so there’s no need to worry about theft. Overall, this tech makes life much simpler and driving out more hassle-free.
