How does the Kia Stonic's smart key work?

I recently purchased a Kia Stonic and was curious about how the smart key feature works. Can you provide some insight into how the key communicates with the car and how to properly use it?

The Kia Stonic's smart key uses radio-frequency identification (RFID) technology to communicate with the car's built-in receiver. When you are within a certain range of the car, the key sends a unique signal to the car, allowing you to lock, unlock, or start the vehicle without actually inserting the key into the ignition.

To use the smart key, simply keep it in your pocket or bag while near the car and press the button on the door handle to unlock it. To start the car, press the start/stop button with your foot on the brake. Just make sure to keep the key within range or the car will not start.

One tip I have for you is to always have a spare key nearby in case the battery dies or you accidentally lock your key inside the car. Also, make sure to keep the key away from any other electronic devices as they can interfere with the key's signal.
