To utilize the feature, the driver must apply a finger to the sensor located in or near the door handle or lock button (depending on the vehicle configuration). This is similar to the way smartphones and tablets with the fingerprint scanner inside works.

Another way that a smart key keeps vehicles safe is by not sending the same frequency signal over and over again. If a fob broadcasted the same signal every time it locked the door remotely or opened the trunk, this could let thieves who are adept at technology to hotwire vehicles and drive them away. smart key replacement keys emit a distinct signal each time a trunk or door is opened remotely.

Smart keys also prevent the theft of cars by thieves at fuel stations and other parking lots.
