Smart keys lock and unlock the doors by using fingerprint recognition. To use the feature, the driver has to place their finger on the sensor near or inside the door knob or lock handle (depending on vehicle configuration). This is similar to how to unlock a smart car without a key a smartphone or tablet with an embedded fingerprint scanner functions.

A smart keys for cars key can also help protect cars by not transmitting the exact frequency signal repeatedly. If a key sent an alert each time it opened or locked a trunk remotely, it will allow tech-savvy thieves to use hotwires to connect cars and remove them. Smart keys emit a distinct signal each time a trunk or door is opened remotely.

Smart keys also stop cars from being stolen by thieves at fueling stations and other parking areas. Smart keys emit a low frequency signal that can only be picked up by nearby smart keys, not by objects or individuals outside the vehicle. The signal is detectable just within 10 cm of a smart key. Thus, it is impossible to take your vehicle away by taking the transmission.

Convenience

Smart keys eliminate the need to dig through your pockets to find a key or even lock the vehicle using a remote. Instead, just tap on your phone's app to unlock or start the engine, and then drive away!

Smart keys, unlike traditional key fobs, which transmit the signal with low power, communicate with your car through radiofrequency signals. The key fob comes with an encrypted chip that the antenna inside your car can recognize. If you are within the proximity to your vehicle, it will open the doors and start the engine.

Some smart keys also save settings for the seats or steering wheel, as well as mirrors, allowing you to set them by pressing a single button. This feature is becoming increasingly well-known, and a rising number of manufacturers are adding this feature to their vehicles.

Smart key fobs emit low-frequency signaling that can be picked up by other devices that open doors or even pop the boot. This is a tactic known as a relay attack and it's been used by tech-savvy thieves to steal vehicles from motorists at fuel stations, as well as parking spaces.

However, the majority of smart key systems offer an alternate method of opening and restarting the vehicle if the battery dies.
