The RFID signal transmitted between a key fob and car is unique, encoded and connected to the vehicle's computer. This makes it impossible for criminals with a technological background to hotwire a stolen car equipped with the key fob. Key fobs can also be programmed to send a new frequency signal every time they're used, so the computer that's onboard won't recognise an old one as the "true" signal.

Security

Many people are hesitant to use digital keys for their car due to the fact that they are worried about security. While having a physical key fob on hand may feel more secure, it's important to recognize that digital keys are also more secure than you might think.

Smart keys send a unique encrypted message each time the remote is unlocked.

Just like any battery-operated device, a smart key's battery will eventually be depleted of power. The majority of systems have a backup system to open the car and then start it in the event that the battery fails. The emergency procedure can differ but usually it involves holding the key in proximity to the sensor for the lock on the car or pressing a button that activates the emergency start.
