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

Security

Many people are reluctant to adopt digital car keys due to the fact that they worry about security. While having a physical key fob to hand does feel more secure, it's important to know that digital keys are also more secure than you might think.
