Security

Many drivers are hesitant to give control of their vehicle to a virtual fob via a smartphone. Security is among the most important concerns. The good news is that a smart key has many of the same features as a traditional car fob.

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

Smart keys can also make cars safer by not sending the exact same frequency signal repeatedly. If a smart key sends a signal every time it opened or unlocked a trunk remotely, this allows thieves with a technological advantage to hotwire cars and eliminate them. Fortunately, this isn't a problem because smart car key programming near me keys emit a unique encrypted signal every time a door is opened or the trunk is remotely opened.

Smart keys also protect the theft of cars by thieves at fueling stations and other parking spaces. Smart keys emit a low frequency signal that can only be detected by nearby smart fortwo key programming keys, and not by people or other objects outside the vehicle. The signal can be recognized within 10 cm of the smart key, meaning it is difficult for anyone to steal your car by grabbing a transmission from a fob that is nearby.

Convenience

Smart keys will no longer require you to dig through your pockets to find a key or to lock your vehicle using remote. You can open your car door or start it by tapping the app on your smartphone.

Contrary to traditional key fobs that transmit a low-power signal, smart keys communicate with your vehicle via radiofrequency waves. The key fob comes with an encrypted chip that the antenna inside your car can recognize. If you reach the range of your car it will open the doors and/or start the engine.

Some smart keys can also save settings for the steering wheel, mirrors, and the seat. Then, you can change them by pressing a single button. This feature is becoming increasingly popular, and a growing number of manufacturers are adding this feature to their vehicles.

The automotive smart key market is growing rapidly due to the rising demand for security and safety features.

This feature is convenient however it can be risky if the driver isn't careful to remove the key fob from their pocket before leaving or entering the vehicle. The reason is that smart key fobs emit low-frequency signals that can be picked up by another device that can unlock the doors or open the trunk. It's a tactic referred to as relay attack, and it's been employed by tech-savvy thieves to steal vehicles from motorists at fuel stations, as well as in parking spaces.

The majority of smart key systems come with a backup method to start and open the vehicle in the case of the battery being dead.

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal each time they unlock the door or remotely pop the trunk. This means that a cyber-savvy criminal could be able to gain access to the system to steal your vehicle. Smart car keys, however, send out an encrypted signal each time they do this. This makes them harder to hack and harder to be exploited by smart thieves.

Certain vehicles also allow you to start your car by simply walking up to it and pressing the button. These systems, unlike conventional models that require you insert and turn the keys and are powered by key fob batteries.
