The RFID signal that is sent between the key fob and the vehicle is unique, encrypted and linked to the onboard computer, making it almost impossible for thieves who are tech-savvy to connect a stolen vehicle equipped with one. The fobs can also be programmed to send a different frequency signal every time they're used, to ensure that the computer doesn't recognize the old one as the real signal.

Security

A lot of people are hesitant to adopt digital keys as they are concerned about security.
