The RFID signal that is transmitted between a key fob and car is unique, encoded, and connected to the car's onboard computer. This makes it almost impossible for tech-savvy criminals to connect a stolen vehicle equipped with a key fob. These fobs are also programmable to send a different frequency signal every time they're used, to ensure that the computer doesn't recognize that old one as the genuine signal.

Security

Many people are reluctant to adopt digital keys as they are concerned about security. While having a physical key fob in your hand can feel more secure, it's important to know that digital keys are more secure than you think.

Most systems come with an emergency system that allows you to open the car's doors and start it if the battery is not able to function.
