Smart Car Key Security Features A smart key communicates with your vehicle on a constant basis whether it's in your pocket or on your desk. They talk to each other by using radiofrequency signals.

Security Many drivers aren't keen to give control of their car to a virtual fob via the phone. Security is among the primary concerns. The good news is that a smart car key can be used with much of the same security features as the traditional fob. Smart keys can lock and unlock the doors with fingerprint recognition. To use the feature, a driver must put their finger on a sensor located near or inside the lock button or door handle (depending on the configuration of the vehicle). This is similar to how a smartphone or tablet with a fingerprint scanner integrated functions. Another way that smart keys can keep cars secure is by not sending the same frequency signal over and over again. If a smart key sends a signal each time it opened or locked a trunk remotely, this will allow tech-savvy thieves to wire cars to take them away. Smart keys emit a unique signal every time a trunk or door is opened remotely. Smart keys can also help in preventing theft of cars at gas stations or other parking spaces. Smart keys emit the signal at a low frequency that can only be picked up by nearby smart keys, not by people or other objects outside the vehicle. This signal can only be recognized within 10 cm of the smart key, which means it is impossible for someone to steal your car just by picking up a signal from a nearby fob.

However, many smart key systems include a backup method for opening and starting the car if the battery dies. The driver will usually put the dead key in an opening, or keep it close to a specific area in the cockpit, to activate the emergency starting system.
