Security

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

Smart keys, for instance, utilize fingerprint recognition to unlock and lock doors. To use the feature, the driver needs to apply a finger to the sensor that is placed near the door handle or lock button (depending on the vehicle's configuration). This is similar to how a smartphone or tablet with an embedded fingerprint scanner operates.

Another way that smart keys help keep cars safer is by not sending the same frequency signal over and over again. If a smart key sends an individual signal each time it was unlocked or opened a trunk remotely, it will allow tech-savvy thieves to connect cars to hotwires and remove them. Smart keys emit a unique signal each time a trunk door is opened remotely.

Smart keys also help prevent vehicles from being taken by thieves at fuel stations and other parking spaces. Smart keys emit the signal at a low frequency that can only be detected by nearby smart keys, not by people or other objects outside the vehicle. The signal can be detected only within 10 cm of a smart key. This means it is impossible to steal your vehicle by simply picking up a transmission.

Convenience

Smart keys eliminate the need to dig through your pockets for keys or to lock your car using remote. You can unlock your car or begin it by tapping the app on your smartphone.

In contrast to traditional key fobs that transmit a low-power signal smart keys communicate with your vehicle using radiofrequency signals. The key fob has an encrypted chip that the antenna inside your vehicle detects. When you are within range of your car it will open the doors and/or start the engine.

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

The automotive smart key market is growing because of the increasing demand for safety and security features. These features minimize the wear and tear on the ignition system in a car and ensure that the driver is the only person who has the ability to stop or start the engine. Smart keys also notify the driver when the battery is in low and make it more difficult for thieves to steal the vehicle.

Certain systems let you open the door from a distance if your smart key for cars key battery goes out. It is recommended to keep a spare mechanical key in your wallet, or in a secure location.

Autonomy

Rather than a key fob that must be in the driver's pocket to open or start a car, smart key systems function when the car door handle or the trunk release button is pressed. These systems also operate when a sensor detects the driver is near.

The goal is to stop the need to use a key fob while driving, allowing drivers to focus on driving safely and secure. The technology is already available in a few luxury vehicles, and it's gaining popularity among major automakers trying to keep pace with customer demand.

This feature is useful however, it could be risky if someone does not take the key fob out of their pocket prior to leaving or entering the vehicle. Smart key fobs emit low-frequency signals that could be picked up by other devices that open doors or pop the boot. It's a tactic referred to as relay attack, and it's been employed by thieves with the latest technology to take vehicles from motorists at fueling stations, and even in parking garages.

Most smart key systems do have a backup system to start and open the vehicle in the event of an insufficient battery. The driver must usually place the dead key fob into a slot or hold it near a designated area in the cabin to activate the emergency start system. This usually involves an inductive coil which transfers energy from the key to the car.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they unlock the door or remotely pop the trunk. This means a tech-savvy criminal could possibly gain access to the system and steal your vehicle. Smart car keys emit a different encrypted code every time they perform the task. This makes them much harder to crack, and more difficult for thieves who are tech-savvy to make use of.

Certain vehicles allow you to start the car by walking up to it, pressing a button. In contrast to traditional models that require you to insert and turn the key to start the engine, these systems are powered by a key fob battery. The key fob will send an alert to the car's radio to notify it that you're close to the vehicle, and it will then be able to open its power doors and begin the engine.
