To access the feature, the driver has to place their finger on a sensor placed in or near the door handle or the lock button (depending on the vehicle configuration). This is similar to the way a tablet or smartphone with a fingerprint scanner embedded functions.

Another way that a smart key keeps cars safer is by not sending the same frequency signal over and over again. If a fob broadcasted the same signal each time it unlocked the door remotely or opened the trunk, it would let thieves who are adept at technology to connect vehicles to hot wires and take them away. Thankfully, this is not an issue since smart keys emit a distinct encrypted signal each time an opening is made on a door or the trunk is remotely opened.

Smart keys also help prevent cars being stolen at gas stations and other parking spaces. This is because they transmit an extremely low-frequency signal that could be picked up by the smart key in close proximity, however, not by any other person or objects outside of the vehicle. The signal can only be identified within 10 cm of the smart key, which means it is not possible for anyone to steal your car just by stealing a transmission from a nearby fob.

This feature is helpful, but it can also be risky if the driver does not take the key fob out of their pocket prior to entering or leaving the vehicle. The reason is that smart key fobs emit a low-frequency signal that can be picked up by another device that can unlock the doors or open the trunk. This is a technique called a relay, and it's used by hackers to steal cars at fueling stations as well as parking spaces.

However, most smart key systems include an alternative method of opening and starting the vehicle in the event that the battery goes out.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal every time they open the door or remotely open the trunk. This means that a hacker could potentially penetrate the system and take your vehicle. Smart car keys, however, put out a different encrypted signal each time they perform this function. This makes them harder to break and more difficult to exploit by tech-savvy thieves.

Certain vehicles allow you to start your car by simply walking up to it and pressing the button.
