Security

Many drivers are hesitant about handing control of their vehicle to a digital key on a smartphone, with security being one of the most important concerns. The good news is that smart car keys have much of the same security features as traditional fobs.

Smart keys can lock and unlock the doors through fingerprint recognition. To access the feature, the driver must apply a finger to the sensor located in or near the door handle or the lock button (depending on the configuration of the vehicle). This is similar to the way smartphones and tablets with a fingerprint scanner integrated operates.

A smart key can also help protect cars by not transmitting the exact frequency signal repeatedly. If a fob sent an individual signal each time it opened or unlocked the trunk remotely, this would enable tech-savvy thieves wire cars to drive them away. Fortunately, this isn't an issue because smart keys emit an encrypted signal every when a door is opened or the trunk is opened remotely.

Smart keys also prevent cars from being stolen by thieves at fuel stations as well as other parking spots. This is because they send an extremely low-frequency signal that could be detected by an adjacent smart key but not by people or objects that are not within the vehicle. The signal can only be detected within 10 centimeters of the smart key, which means it is not possible for someone to steal your car by picking up a transmission from a nearby fob.

Convenience

Smart keys, unlike traditional key fobs, which transmit the signal with low power and communicate with your car via radiofrequency waves. The key fob comes with an encrypted chip that the antenna in your car can recognize. If you are within distance of your vehicle, it will unlock the doors and begin the engine.

Some smart keys also store settings for the seats or steering wheel, as well as mirrors, allowing you to set them by pressing a single button. This feature is becoming increasingly popular and a growing number of manufacturers are introducing it to their automobiles.

The market for car smart keys 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 has the ability to start or stop the engine.

The idea is to make it unnecessary to press the key fob button while driving, so drivers can concentrate on driving safely and securely. The technology is already in use in some high-end vehicles, and it's growing in popularity with major automakers trying to keep up with the customer demand.

While this feature is convenient however, it can be a risk when the driver fails to take their key fob out of the pocket prior to entering or exiting the vehicle. Smart key fobs emit low-frequency signaling that can be detected by other devices that open doors or even pop the boot. It's a tactic called relay attack, and has been used by thieves who are tech-savvy to take vehicles from motorists at fueling stations, as well as in parking lots.

Most smart key systems do include a backup mechanism to open and start the vehicle in the event of an insufficient battery. The driver typically has to place the dead key fob into a slot or put it in a designated part of the cockpit to trigger an emergency start system, which typically consists of an inductive coil which transfers energy from the key to the vehicle.

Safety

The smart key will stop the vehicle from being operated and unlock the trunk the keys remain in the trunk. This prevents you from getting locked from your car in an unsafe area or while completing on errands.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock the door or remotely open out of the trunk. This means that a criminal with a technologically advanced mind could be able to penetrate the system to take your vehicle. Smart car keys, however, put out an encrypted signal that is different each time they are used. This makes them much more difficult to crack, and more difficult for tech-savvy thieves to exploit.

Some vehicles also allow you to start your car by simply walking towards it and pressing the 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's battery. The key fob transmits a signal to your car's antenna, letting it know that you're in close proximity. The car will activate the power doors and begin its engine.
