Smart keys, for instance, use fingerprint recognition to lock and unlock doors. To make use of this feature, a person must place their finger on a sensor near or inside the lock button or door handle (depending on the vehicle's configuration). This is similar to how a phone or tablet with an embedded fingerprint scanner functions.

Another way that smart keys help keep vehicles safe is by not sending the same frequency signal repeatedly again. If a fob sent the same signal every time it locked the door remotely or opened the trunk, this would let thieves who are adept at technology to use hotwires to take them away. Thankfully, this is not a problem because smart keys emit a different encrypted signal each when a door is opened or the trunk is remotely opened.

Smart keys also help prevent the theft of cars by thieves at fueling stations and other parking lots. This is because they transmit an extremely low-frequency signal that could be detected by a nearby smart key, but not by other people or objects that are not within the vehicle.

The key fob is equipped with an encrypted chip that the antenna inside your car recognizes. If you are within the reach of your vehicle it will unlock the doors or start the engine.

Certain smart keys also store settings for the steering wheel, mirrors and seat. Then, you can change them by pressing a single button. This feature is becoming more popular and a rising number of manufacturers are adding it to their automobiles.

These features help reduce the wear and tear of the ignition system of a car and ensure that the driver is the sole person who can stop or start the engine.

Autonomy

Rather than an actual key fob that needs to be kept in the pocket of the driver to unlock or start a car, smart key systems work when the door handle or trunk release button is pressed. These systems also operate when a sensor senses the driver is within.

The idea is to make it unnecessary to press a key fob button while driving, allowing drivers to concentrate on driving safely and secure. The technology is available in some premium vehicles, and it's gaining popularity among major automakers who are trying to keep up with customer demand.

Smart key fobs emit low-frequency signals that can be detected by other devices that can unlock doors or open the boot. This is known as relay and has been used by tech-savvy criminals to steal cars at fuel stations and parking spaces.

However, most smart key systems have a backup method for opening and restarting the vehicle if the battery dies. The driver is required to place the dead key fob into a slot or hold it close to a specific area in the cockpit, to start the emergency starter.

While it's crucial to be aware that your vehicle isn't spying on you however, the fact that the key fob sends these signals makes it possible for a criminal to intercept them and gain control of the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock doors or remotely pop out of the trunk. This implies that a hacker could gain access to the system to steal your vehicle. Smart car keys, however, send out a different encrypted signal each time they use this function. This makes them more difficult break and more difficult to be exploited by thieves with a technological edge.

Certain vehicles allow you to start the car by walking up to it and pressing a button. These systems, in contrast to traditional models that require you to insert and turn the keys, are powered by key fob batteries. The key fob sends a signal to the car's antenna to tell it that you are close, and the car will then open its power doors and begin the engine.
