To utilize the feature, the driver must apply a finger to the sensor located in or near the door handle or the lock button (depending on the vehicle configuration). This is similar to the way a smartphone or tablet with a fingerprint scanner integrated functions.

Another way that smart keys can keep cars safer is by not sending the same frequency signal repeatedly again. If a fob broadcasted the same signal every time it opened a door or remotely opened the trunk, this would allow tech-savvy thieves to use hotwires to remove them. Thankfully, this is not an issue because smart keys emit a distinct encrypted signal every time the door is opened or the trunk is remotely opened.

Smart keys can also in preventing theft of cars at gas stations and other parking spaces. This is because they transmit an extremely low-frequency signal that could be picked up by an adjacent smart key but not by other people or objects that are not within the vehicle. The signal can only be identified within 10 cm of the smart key. Therefore, it is not possible for anyone to steal your car just by picking up a transmission from a fob that is nearby.

This is a tactic known as a relay attack and has been used by thieves who are tech-savvy to take cars from drivers at fueling stations, as well as parking garages.

However, many smart key systems offer an alternate method of opening and re-starting the vehicle when the battery is dead. The driver should usually insert the dead key fob into a slot, or hold it close to a special area in the cockpit, to start the emergency starter.

Certain vehicles allow you to start the car by walking up to it, and pressing the button. These systems, unlike traditional models that require you insert and turn the keys and are powered by key fob batteries.
