The RFID signal transmitted between the key fob and the vehicle is unique, secure and connected to the onboard computer which makes it nearly impossible for thieves who are tech-savvy to connect a stolen car equipped with one. The fobs can also be programmed to transmit a different frequency signal each time they're used so that the onboard computer doesn't recognize that old one as the authentic signal.

Security

Many people are reluctant to switch to digital keys for cars because they are concerned about security. While having a physical key fob in hand can feel more secure but digital keys are more secure than many think.
