The RFID signal sent between the key fob to a car is unique, secure and connected to the onboard computer which makes it nearly impossible for hackers with the latest technology to connect a stolen vehicle equipped with one. These key fobs can be programmed to transmit the same frequency signal each time they're used. This means that the computer onboard won't recognize an old one as the "true" signal.
Security
Many people are reluctant to use digital keys for their car due to the fact that they are concerned about security. While having a physical key fob at hand might feel more secure the digital keys are more secure than most people believe.
