The RFID signal sent between the key fob and the vehicle is unique, encrypted and linked to the computer in the car, making it almost impossible for tech-savvy thieves to wire a stolen vehicle equipped with one. These fobs are also programmable to transmit a different frequency signal each time they're used so that the computer doesn't recognize the old one as the real signal.

Security

Many people are hesitant to make the switch to digital car keys due to the fact that they worry about security. While having a physical fob in hand can feel safer however, digital keys are more secure than most people believe. The digital keys are encrypted and the signal they transmit to a car can be verified by an onboard computer. The car won't begin in the event that the smart key fob is compromised.

Smart keys transmit a unique encrypted signal each when the vehicle is unlocked or remotely opened.

Like any other battery-powered device, a smart key's battery will eventually deplete its juice. Most of the systems are designed with a backup strategy to open and start the car in the event that the battery fails. The emergency method varies in the majority of cases, but it involves keeping the key within the range of the car's lock sensor or pressing a button on the key that triggers the emergency start.
