When the smart key is in the range of the computer inside your vehicle is able to recognize the rolling code projected by the key fob and validates it prior getting the engine started. This helps deter thieves.

Security

Many drivers are reluctant to hand over control of their vehicle to a virtual fob that is on smartphones. Security is one of the primary concerns. The good news is that a smart car key has many of the same security features as an ordinary fob.

Smart keys are able to lock and unlock the doors through fingerprint recognition. To use the feature, a driver must put their finger on a sensor located near or inside the door knob or lock handle (depending on the vehicle's configuration). This is similar to how a tablet or smartphone with a fingerprint scanner embedded operates.

Another way that smart keys keep vehicles safe is by not sending the same frequency signal over and over again. If a fob transmitted the same signal every time it unlocked the door remotely or opened the trunk, it could let thieves who are adept at technology to wire vehicles and drive them away. Smart keys emit a unique signal each time a trunk or door is opened remotely.

Smart keys can also help in preventing theft of cars at gas stations and other parking areas. Smart keys emit a low-frequency signal that can only be detected by nearby smart key for car keys, and not by people or other objects that are not within the vehicle. The signal is detectable at a distance of 10 cm from a smart key. Therefore, it is impossible to steal your vehicle simply by taking a transmission.

The key fob comes with an encrypted chip that the antenna inside your car recognizes. When you are within range of your car it is able to open the doors and/or start the engine.

Some smart keys also save settings for the seats or steering wheel, as well as mirrors that allow you to alter them with a single click. This feature is becoming more popular and a growing number of manufacturers are incorporating it to their automobiles.

The industry of automotive smart keys is booming because of the increasing demand for security features. These features reduce the wear and tear on the ignition system of a vehicle and ensure that the driver is the sole person who can stop or start the engine. Smart keys can also inform the driver if the battery is not fully charged which makes it difficult for thieves to steal the car.

Some systems let you open the door from a distance if your smart key battery goes out. It's best to keep a backup key in your wallet or another safe location.

Autonomy

Certain smart key systems work without a key fob that is in the pockets of drivers. Instead, they operate by pressing the trunk release or door handle. They also function when a sensor detects the driver is within.

The idea is to eliminate the necessity of pressing the key fob button while driving, so drivers can concentrate on driving safely and securely. The technology is available in certain luxury vehicles, and is growing in popularity with automakers that are working to meet consumer requirements.

This feature is convenient however, it could be risky if a driver isn't careful to take the key fob out of their pocket prior to leaving or entering the vehicle. This is because smart key fobs emit an low-frequency signal which can be picked up by a device that could open the doors, or even pop the trunk. It's a tactic called relay attack, and it's been used by tech-savvy thieves to take cars from drivers at fueling stations and also in parking lots.

However, the majority of smart key systems come with an alternate method of opening and restarting the vehicle when the battery is dead. The driver must usually place the dead key in a slot, or hold it near to a designated area in the cockpit to activate the emergency starting system.

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal each time they open the door or remotely open the trunk. This means a tech-savvy criminal could gain access to the system and take your vehicle. Smart car keys, however, put out an encrypted signal each time they do this. This makes them difficult to break and more difficult to exploit by hackers.

Certain cars allow you to start the car by walking up to it and pressing a button. Unlike traditional models that require you to insert and turn the key and then turn it on, these systems are powered by a key fob battery. The key fob sends an indication to your car's antenna, telling it that you're near. The vehicle will then start the power doors and start its engine.
