Smart Car Key Security Features

Smart keys communicate with your car continuously, whether they're in your pocket or on your desk. They talk to each other through radiofrequency waves.

When the smart key is within range, the computer in your car detects and validates the rolling code projected from the key fob before starting the vehicle. This can deter thieves.

Security

Many drivers aren't comfortable the transfer of control of their vehicle to a virtual key that is stored on a smartphone, with security being among the most important concerns. The good news is a smart key has many of the same features that a traditional car fob does.

For starters, smart keys make use of fingerprint recognition to lock and unlock doors. To utilize the feature, a driver must place their finger on the sensor near or inside the door knob or lock handle (depending on vehicle configuration). This is similar to how a smartphone or tablet with an embedded fingerprint scanner functions.

Smart keys can also make cars safer by not sending the exact same frequency signal repeatedly. If a fob sent a signal every time it opened or locked a trunk remotely, it will allow tech-savvy thieves to hotwire cars and remove them. Fortunately, this isn't an issue since smart keys emit an encrypted signal each when doors are opened or the trunk is opened remotely.

Smart keys also stop cars from being taken away by thieves at fueling stations as well as other parking spots. This is because they send the signal at a low frequency that can be detected by a nearby smart key, but not by other people or objects that are not within the vehicle. The signal can be detected within 10 cm of the smart car replacement key key, meaning it is virtually impossible for someone to steal your car by stealing a transmission from a fob that is nearby.

Convenience

Using smart keys eliminates the need to dig through your pockets to locate the key or secure your car using the remote control. Instead, simply tap your phone in the app to unlock or start the engine and drive away!

Contrary to traditional key fobs that transmit a low-power signal, smart key repair keys connect to your vehicle through radiofrequency waves. The key fob contains an encrypted chip that the antenna inside your car can recognize. When you are within range of your vehicle, it will open the doors and start the engine.

Certain smart keys also save settings for the steering wheel, mirrors and seat. You can then set them by pressing one button. This feature is becoming increasingly popular, and a growing number of manufacturers are incorporating this to their vehicles.

The automotive smart key market is booming due to increasing demand for security and safety features. These features reduce the wear and tear on the ignition system of a vehicle and ensure that only the driver is able to start or stop the engine. Smart keys also notify the driver if the battery is in low, making it harder for thieves to steal the vehicle smart key.

Some systems will also allow you to unlock your door from a distance in the event that the battery for your smart key fails. However, it's advisable to have a backup mechanical key that you can keep in your wallet or other safe.

Autonomy

Rather than a key fob that must be carried by the driver to unlock or start a car, smart key systems operate when the car door handle or the trunk release button is hit. They also function when a sensor senses the driver is in close proximity.

The idea is to avoid the need to use a key fob while driving, so that drivers can concentrate on driving safely and secure. The technology is currently available in a few luxury cars and is gaining popularity among automakers of all kinds who are trying to meet customer demands.

While this feature is convenient, it can be dangerous in the event that the driver does not take their key fob from the pocket before entering or exiting the vehicle. The reason is that smart key fobs emit low-frequency signals that can be detected by a different device that can unlock the doors or open the trunk. It's a tactic referred to as relay attack, and it's been used by thieves who are tech-savvy to steal cars from drivers at fuel stations, as well as parking garages.

However, most smart key systems include an alternate method of opening and starting the vehicle if the battery dies. The driver is required to put the dead key fob into a slot or hold it near a special space in the cockpit, to trigger an emergency start system, which typically consists of an inductive coil that transfer energy from the key to the car.

Safety

The smart key has a built-in feature of security that will lock your vehicle when you leave. The smart key can shut down the vehicle and unlock the trunk even when keys are in the trunk. This will prevent you from being locked out of your car in a dangerous area or when you are running errands.

Contrary to conventional keys smart key fob connects to the vehicle using radiofrequency signals. It's important to keep in mind that your car is not spying on you. However, since the key fob transmits these signals, it is possible for a criminal to intercept them and control the vehicle.

Open Road Auto Group explains that traditional key fobs send out the same frequency signal every time they unlock the door, or remotely open the trunk. This means that a hacker could hack into the system and steal your vehicle. Smart car keys emit an encrypted code that changes each time they perform a function. This makes them harder to penetrate and more difficult to be exploited by thieves with a technological edge.

Certain vehicles also allow you to start your car by simply walking up to it and pressing the button. These systems, in contrast to traditional models that require you insert and turn the keys to start the car, are powered by key fob batteries. The key fob will send an indication to the car's signal to signal it that you're near, and the car can then activate its power doors and begin the engine.
