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

Another way that smart keys can keep cars secure is by not sending the same frequency signal over and over again. If a key sent the same signal every time it locked a door, or remotely opened the trunk, it would allow thieves who are tech-savvy to use hotwires to take them away. Fortunately, this isn't an issue because smart keys emit a distinct encrypted signal each time an opening is made on a door or the trunk is opened remotely.

Smart keys can also prevent cars being stolen at gas stations or other parking spots.

This makes them difficult to crack and more difficult to be exploited by smart thieves.

Some vehicles allow you to start the car by walking up to it, and pressing a button.
