To utilize the feature, a person must put their finger on the sensor in or near the lock button or door handle (depending on the configuration of the vehicle). This is similar to how a smartphone or tablet with an embedded fingerprint scanner works.

Another way that smart keys can keep cars safer is by not sending the same frequency signal over and over again. If a fob transmitted the same signal each time it unlocked a door or remotely opened the trunk, it would let thieves who are adept at technology to wire vehicles and remove them. Smart keys emit a different signal each time a trunk or door is opened remotely.

Smart keys can also help protect cars from theft at gas stations and other parking areas. Smart keys send a low-frequency signal that can only be picked up by nearby smart car key replacement keys, not by any other objects that are not within the vehicle. The signal is only detected within 10 cm of the smart key. Therefore, it is not possible for someone to steal your car just by picking up a transmission from a fob that is nearby.

The key fob comes with an encrypted chip that the antenna in your car recognizes. When you get within proximity to your car it will open the doors and/or start the engine.

Some smart keys can also store settings for the steering wheel, mirrors, and the seat. You can then alter them by pressing one button. This feature is becoming more popular, and a greater amount of manufacturers are adding this to their vehicles.

The automotive smart key market is growing due to the increasing demand for safety and security features. These features help reduce the wear and tear on a car's ignition system and ensure that the driver is the only person who can stop or restart the engine.

Although this feature is convenient, it can be dangerous in the event that the driver does not take their key fob out of the pocket prior to going into or out of the car. That's because smart key fobs emit low-frequency signals that can be detected by a device that could open the doors or even the trunk. This is a tactic known as a relay attack, and it's been used by thieves with the latest technology to take vehicles from motorists at fueling stations as well as in parking areas.

However, all smart key systems come with a backup method for opening and restarting the vehicle in the event that the battery goes out. The driver typically has to place the dead key in an opening or keep it near a special area of the cockpit to trigger an emergency start system, which typically consists of an inductive coil that transmits energy from the key to the car.

Open Road Auto Group explains that traditional key fobs send out the same frequency signal every time they open the door, or remotely open the trunk. This means that a criminal with a technological edge could gain access to the system and steal your vehicle. Smart car keys emit an encrypted message every time they perform some function. This makes them more difficult crack and more difficult to be exploited by smart thieves.

Certain vehicles allow you to start the car by walking towards it, and pressing a button. These systems, in contrast to traditional models that require you to insert and turn the keys and are powered by key fob batteries.
