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

A smart key can also ensure the safety of vehicles by not sending the exact frequency signal repeatedly. If a fob sent a signal every time it opened or unlocked a trunk remotely, it will allow tech-savvy thieves to connect cars to hotwires and take them away. Thankfully, this is not an issue because smart keys emit a different encrypted signal each when the door is opened or the trunk is opened remotely.

Smart keys can also protect cars from theft at gas stations or other parking spaces.
