Key fobs can perform all of these functions via radio transmissions between the car key fob and the car, using low-power wireless technology. This is a great option for drivers who are constantly in motion and don't have much time to spare.

A smart key is typically shaped more like a plastic card than an actual key, and it can be used to open the trunk or car's doors when the fob's button is pressed. Some even come with a built-in touchscreen to allow drivers to control certain settings on their vehicle, including audio and climate.

The RFID signal sent between the key fob and the car is unique, encrypted and tied to the onboard computer making it nearly impossible for tech-savvy thieves to connect a stolen vehicle equipped with one. They can also be programmed to transmit a different frequency signal every time they're used, so that the computer doesn't recognize the old one as the genuine signal.

Security

A lot of people are hesitant to adopt digital car keys due to the fact that they worry about security. While having a physical fob on hand may feel safer, digital keys are actually more secure than people believe.

Smart keys transmit a distinct, encrypted message every time the remote is unlocked.

Like any other battery-powered device the battery in a smart key will eventually run out of juice. Most systems come with backup systems to unlock the car and then start it in case the battery fails. The emergency method can vary, but it usually involves holding the key in proximity to the sensor for the lock on the car or pressing a button which activates the emergency starter.
