The RFID signal that is transmitted between the car and a key fob is unique, encoded, and connected to the car's onboard computer. This makes it impossible for tech-savvy criminals to hotwire a stolen car equipped with a key fob. These fobs can also be programmed to transmit a New Car Key Fob frequency signal every time they're used, so the onboard computer won't recognize an old one as the "true" signal.

Security

Many people are reluctant to make the switch to digital car keys because they worry about security. While having a tangible key fob on hand may feel more secure, it's important to recognize that digital keys are also more secure than you think. They're encrypted and the signal that they transmit to a vehicle is verified by a computer onboard. The car won't start if the smart fob is stolen.

Most systems are designed with a backup strategy to open and start the car when the battery is not working. The emergency method can vary however, it is usually holding the key within the proximity to the sensor for the lock on the car or pressing a key button which activates the emergency starter.
