This is similar to how a phone or tablet equipped with an embedded fingerprint scanner operates.

Another way that a smart key market key keeps vehicles safe is by not sending the same frequency signal repeatedly again. If a key sent the same signal every time it opened doors or remotely opened the trunk, this could allow thieves who are tech-savvy to hotwire vehicles and drive them away. Thankfully, this is not an issue as smart keys emit a different encrypted signal each when an opening is made on a door or the trunk is remotely opened.

The key fob has an encrypted chip that the antenna in your car smart key can recognize. If you are within the range of your vehicle, it will unlock the doors and start the engine.

Certain smart keys also store settings for the steering wheel, mirrors, and seats. You can then alter them by pressing one button. This feature is becoming more popular and a growing number of manufacturers are introducing it to their vehicles.
