Smart Car Key Security Features

Smart keys communicate with your vehicle all the time whether it's in your pocket or sitting on your desk. They talk to each other through radiofrequency waves.

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

Security

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

Smart keys, for instance, utilize fingerprint recognition to lock and unlock doors. To utilize the feature, a driver must place 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 function.

Smart keys can also help protect cars by not sending the same frequency signal repeatedly. If a fob sent the same signal each time it unlocked doors or remotely opened the trunk, this could let thieves who are adept at technology to hotwire vehicles and remove them. Fortunately, this isn't a problem because smart keys emit an encrypted signal each time the door is opened or the trunk is opened remotely.

smart fortwo key fob keys also help prevent the theft of cars by thieves at fuel stations as well as other parking spots. Smart keys emit the signal at a low frequency that can only be picked up by nearby smart keys, not by other objects or people that are not within the vehicle. This signal can only be identified within 10 cm of the smart key. Therefore, it is difficult for someone to steal your car just by grabbing a transmission from a nearby fob.

Convenience

Smart keys eliminate the need to search your pockets for a key, or lock the car using a remote. Instead, just tap on your phone's app to unlock the car or start the engine. Then, drive away!

Smart keys, unlike traditional key fobs, which transmit an extremely low power signal that communicates with your car through radiofrequency waves. The key fob is equipped with an encrypted chip that the antenna inside your vehicle detects. If you reach the range of your car it will open the doors and/or begin the engine.

Some smart keys also store settings for the seat, mirrors and steering wheel, allowing you to set them by pressing a single button. 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 growing due to the increasing demand for security features. These features decrease the wear and tear on the ignition system of a car and ensure that only the driver has the ability to start or stop the engine. Smart keys can also alert the driver if the battery is running low and makes it more difficult for thieves to steal the car.

Certain systems let you open the door remotely if the battery of your smart car key fob programming key runs out. It is best to keep a spare mechanical key in your wallet or a safe location.

Autonomy

Certain smart key systems function without a key-fob in the pockets of the driver. Instead, they operate by pressing the trunk release button or door handle. These systems can also be activated when an sensor detects the driver's proximity.

The idea is to eliminate pressing a key fob when driving so that drivers can focus on driving safely and securely. The technology is available in some premium vehicles, and it's growing in popularity with mainstream automakers trying to keep up with customer demand.

While this feature can be useful however, it can also be dangerous if the driver forgets to take their key fob out of the pocket before entering or exiting the vehicle. That's because smart key fobs emit a low-frequency signal that can be detected by a different device that could open the doors or even the trunk. It's a tactic referred to as a relay attack, and it's been used by thieves with a technological advantage to take vehicles from motorists at fueling stations and even in parking areas.

The majority of smart car key coding key systems include a backup mechanism for opening and starting the vehicle in the case of a dead battery. The driver will usually put the dead key fob in an opening, or keep it close to a specific area in the cabin to start the emergency starter. This typically involves an inductive coil that transfers energy from key to car.

Safety

The smart key has built-in security features that locks the vehicle after you leave. It can even shut down the engine and open the trunk if you've locked the keys inside. This will keep you from being locked out of your car in a dangerous area or while running an errand.

As opposed to traditional keys, a smart key fob communicates with the vehicle using radiofrequency signals. It's important to remember that your car is not tracking you. However, since the key fob transmits these signals, it's possible for a criminal intercept these signals and control the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock a door or remotely pop out of the trunk. This means that a cyber-savvy criminal can potentially infiltrate the system and take your vehicle. Smart car keys generate an encrypted message every time they complete an action. This makes them much harder to hack, and also more difficult for thieves who are tech-savvy to exploit.

Certain vehicles allow you to start the car by walking right up to it, pressing the button. These systems, in contrast to traditional models that require you to insert and turn the keys they are powered by key fob batteries. The key fob transmits a signal to the car's antenna tell it that you are close to the vehicle, and it can then turn on its power doors and start the engine.
