Smart Car Key Security Features

Smart keys communicate with your car every day, whether in your pocket or on your desk. They communicate with each other using radiofrequency waves.

If the smart key is within reach, the computer inside your car will recognize and verify the rolling code projected from the key fob before starting the vehicle. This helps to deter thieves.

Security

Many drivers are skeptical about handing over control of their vehicle to a virtual key on a smartphone, with security being one of the most important concerns. The good news is a smart key has many of the same features as a traditional car fob.

For starters, smart keys make use of fingerprint recognition to lock and unlock doors. To use the feature, the driver has to place their finger on a sensor placed in or near the door handle or lock button (depending on the vehicle configuration). This is similar to how a phone or tablet with an embedded fingerprint scanner function.

Smart keys can also make cars safer by not sending the exact same frequency signal repeatedly. If a key sent an individual signal each time it was unlocked or opened the trunk remotely, this would enable tech-savvy thieves use hotwires to connect cars and drive them away. Thankfully, this is not an issue because new smart car key keys emit a unique encrypted signal each when doors are opened or the trunk is remotely opened.

Smart keys also help in preventing theft of cars at gas stations or other parking spaces. Smart keys send the signal at a low frequency that can only be picked up by nearby smart car replacement key keys, and not by any other objects that are not within the vehicle. The signal can only be detected within 10 centimeters of the smart key, which means it is virtually impossible for someone to steal your car by picking up a signal from a fob that is nearby.

Convenience

Smart keys eliminate the need to search your pockets for keys, or lock the vehicle using remote. You can unlock your car and start it by pressing the app on your smartphone.

Smart keys, unlike traditional key fobs that emit a low power signal and communicate with your car through radiofrequency signals. The key fob contains an encrypted chip that the antenna inside your vehicle recognizes. If you are within distance of your vehicle, it will open the doors and start the engine.

Some smart keys also store settings for the seat and mirrors as well as the steering wheel which allows you to adjust them by pressing a single button. This feature is becoming increasingly well-known, and a rising number of manufacturers are incorporating this feature to their vehicles.

The automotive smart key market is booming due to increasing demand for safety and security features. These features decrease the wear and tear on the ignition system of a car and guarantee that only the driver can start or stop the engine. Smart keys also notify the driver if the battery is not fully charged and makes it less difficult for thieves to take the vehicle.

Certain systems will also allow you to unlock your door from a distance in the event that the smart key battery dies. It is recommended to keep a backup key in your wallet or other safe location.

Autonomy

Rather than an actual key fob that needs to be carried by the driver to unlock or start a car, smart car key fob programming key systems work when the car door handle or the trunk release button is pressed. These systems also operate when a sensor detects the driver is nearby.

The idea is to remove the necessity of pressing the key fob button while driving, so that drivers can concentrate on driving safely and secure. The technology is available in a few premium cars and is gaining popularity with mainstream automakers who are working to meet consumer requirements.

This feature is helpful however it can be risky if a driver forgets to take the key fob out of their pocket before leaving or entering the vehicle. The reason is that smart key fobs emit an ultra-low-frequency signal that could be picked up by another device that can open the doors, or even pop the trunk. This is known as relay and has been used by cyber-savvy criminals to steal cars from fueling stations as well as parking spaces.

The majority of smart key systems come with a backup system for opening and starting the vehicle in the case of the battery being dead. The driver should usually insert the dead key fob inside a slot, or hold it close to a specific area in the cabin to trigger the emergency starting system. This usually involves an inductive coil that transmits energy from the car to the key.

Safety

The smart key has a built-in feature of security that locks your vehicle when you leave. It can even shut down the engine and unlock the trunk if you've left the keys inside. This will stop you from being locked out of your vehicle in a dangerous location or when you are running the errands.

Smart key fobs communicate with vehicles using radiofrequency signals, which is different from conventional keys. While it's important to remember that your vehicle isn't spying on your, the fact that the key fob transmits these signals makes it possible for criminals to intercept these signals and gain control of the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they open the door or remotely open out the trunk. This means that a criminal with a technological edge could possibly infiltrate the system and steal your vehicle. Smart car keys generate an encrypted code that changes each time they perform a function. This makes them more difficult crack and more difficult to exploit by tech-savvy thieves.

Some vehicles allow you to start the vehicle by walking up to it, pressing a button. Contrary to traditional models which require you to insert and turn the key in order to start, these systems are powered by a key fob battery. The key fob sends an indication to the car's signal to tell it that you are close, and the car will then open its power doors and start the engine.
