A smart car key fob replacement key is usually shaped more like a plastic card than a key, and can be used to open the trunk or car's doors when a button on the fob is pushed. Some smart keys feature touchscreens that allow drivers to control the vehicle's setting, including audio and climate.

The RFID signal that is transmitted between a key fob and car is unique, encoded, and connected to the vehicle's computer. This makes it nearly impossible for hackers with the right skills to connect a stolen vehicle equipped with the key fob. The fobs can also be programmed to send the same frequency signal each time they're used, so the computer in the car won't be able to recognize an old one as the "true" signal.

Security

Many people are hesitant adopt digital keys as they are worried about security. While having a physical key fob in hand can feel more secure however, digital keys are more secure than many believe.

Most systems are designed with a backup method to open and start the car in the event of a battery failure. The emergency method may differ, but it usually involves holding the key within the proximity to the lock sensor on the car or pressing a button which activates the emergency starter.
