To use this feature, the driver has to place their finger on the sensor near or inside the lock button or door handle (depending on vehicle configuration). This is similar to how a tablet or smartphone that has a fingerprint scanner embedded works.

A smart key could also make cars safer by not sending the same frequency signal repeatedly. If a fob transmitted the same signal every time it unlocked a door or remotely opened the trunk, this would allow tech-savvy thieves to wire vehicles and make them disappear. Fortunately, this isn't an issue as smart keys emit a unique encrypted signal each time a door is opened or the trunk is opened remotely.

Smart keys also prevent vehicles from being taken by thieves at fuel stations and other parking areas. Smart keys send an extremely low-frequency signal that can only be detected by nearby smart car keys keys, and not by objects or individuals outside the vehicle. The signal is detectable only within 10 cm of the smart key. This means it is impossible to steal your vehicle just by taking a transmission.

Smart keys, in contrast to traditional keys that transmit the signal with low power that communicates with your car using radiofrequency waves. The key fob is equipped with an encrypted chip which the antenna in your vehicle detects. When you get within of the car's range it will open the doors and/or start the engine.

Some smart keys can also save settings for the seats and mirrors as well as the steering wheel that allow you to alter them with a single click. This feature is becoming increasingly well-known, and a rising number of manufacturers are incorporating this to their vehicles.

The market for car smart keys is growing rapidly due to the rising demand for safety and security features.

This is because smart key fobs emit an ultra-low-frequency signal that could be picked up by another device that can unlock the doors or open the trunk. This is known as relay and has been used by tech-savvy criminals to steal cars at fuel stations and parking spaces.

However, many smart key systems include a backup method for opening and re-starting the vehicle if the battery dies. The driver must usually place the dead key fob inside the slot, or place it near a designated space in the cockpit to activate the emergency start system.
