Smart Car Key Security Features

Smart keys communicate with your vehicle all the time, whether in your pocket or on your desk. They talk to each other by using radiofrequency signals.

When the smart key is within range, a computer in your vehicle detects the rolling code projected by the fob of the key and validates it prior to beginning the engine. This helps deter thieves.

Security

Many drivers are skeptical about giving control of their vehicle to a virtual key via a smartphone, with security being among the primary concerns. The good news is that smart car keys have many of the same security features as a traditional fob.

Smart keys unlock and lock the doors by using fingerprint recognition. In order to use the feature, the driver must apply a finger to a sensor placed in or near the door handle or the lock button (depending on the configuration of the vehicle). This is similar to the way a tablet or smartphone with a fingerprint scanner integrated operates.

A smart key can also help protect cars by not sending the exact frequency signal repeatedly. If a fob transmitted the same signal each time it opened a door or remotely opened the trunk, it would allow thieves who are tech-savvy to hotwire vehicles and drive them away. smart car key reprogramming keys emit a distinct signal every time a trunk or door is opened remotely.

Smart keys also can help protect cars from theft at gas stations or other parking spots. Smart keys transmit an extremely low-frequency signal that can only be detected by nearby smart key replacement keys, not by objects or individuals outside the vehicle. The signal is detectable at a distance of 10 cm from a smart key. Therefore, it is impossible to take your vehicle away by picking up an engine.

Convenience

Smart keys will no longer require you to search through your pockets to find a key, or lock the car using a remote. You can unlock your car and start it by tapping on the app on your phone.

Smart keys, in contrast to traditional replacement key for smart car fobs that transmit the signal with low power, communicate with your car using radiofrequency waves. The key fob contains an encrypted chip that the antenna inside your car recognizes. When you are within reach of your vehicle it will unlock the doors or start the engine.

Some smart keys can also store settings for the seat mirrors, the steering wheel and seat, allowing you to set them with a single click. This feature is becoming increasingly well-known, and a rising number of manufacturers are incorporating this feature to their vehicles.

The market for automotive smart keys is growing because of the increasing demand for safety and security features. These features reduce wear and tear on the ignition system of a vehicle and ensure that the driver is the only person who can stop or start the engine. Smart keys also notify the driver if the battery is low which makes it difficult for thieves to take the car.

Certain systems allow you to open the door from a distance if your smart car key programming key battery runs out. However, it's best to have a spare mechanical key hidden in your wallet or else secure.

Autonomy

Certain smart key systems work without a key fob that is in the driver's pockets. Instead, they operate by pressing the trunk release or door handle. These systems also operate when a sensor detects that the driver is nearby.

The idea is to eliminate the necessity of pressing the key fob button while driving, so that drivers can concentrate on driving safely and securely. The technology is already present in some premium vehicles, and is gaining traction among major automakers trying to keep pace with customer demand.

While this feature is convenient but it could be risky in the event that the driver does not take their key fob out of the pocket prior to getting into or out of the vehicle. That's because smart key fobs emit a low-frequency signal that can be picked up by another device that could open the doors or even the trunk. It's a tactic referred to as relay attack, and it's been used by tech-savvy thieves to steal vehicles from motorists at fueling stations as well as parking lots.

Most smart key systems do have a backup system for nearby starting and opening the vehicle in the case of a dead battery. The driver must usually place the dead key fob into a slot, or hold it near a designated area in the cockpit, to start the emergency starter. This usually involves an inductive coil that transfers energy from the key to the vehicle.

Safety

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

As opposed to traditional keys, a smart key fob communicates with the vehicle using radiofrequency signals. It's crucial to remember that your car isn't monitoring you. However, because the key fob sends out these signals, it is possible for a criminal to intercept them and take control of the vehicle.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they open the door or remotely pop the trunk. This means that a criminal with a technologically advanced mind can potentially infiltrate the system and steal your vehicle. Smart car keys emit an encrypted code that changes each time they perform the task. This makes them more difficult hack and harder to exploit by hackers.

Some vehicles allow you to start the car by walking towards it, and pressing a button. These systems, in contrast to traditional ones that require you to insert and turn the keys, are powered by key fob batteries. The key fob transmits a signal to your car's antenna, telling it that you're close. The vehicle will then activate the power doors, and begin its engine.
