The RFID signal transmitted between the car and a key fob is unique, encoded and linked to the car's onboard computer. This makes it impossible for hackers with the right skills to connect a stolen vehicle equipped with the key fob. These key fobs can 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 reluctant to make the switch to digital car keys because they fear security. While having a physical key fob to hand does feel safer, it's important to realize that digital keys are more secure than you might think.
