5 Reasons Smart Car Key Programming Is Actually A Good Thing
Vehicle Smart Key Technology
The technology of smart keys in automobiles allows drivers to open and start their vehicle by simply touching the door handle or by putting the key into the pocket. It also enables a range of other adjustments, such as seat positions, internal temperature settings, stereo presets, and mirror positioning.
However, this could also result in security issues.
Security
Smart keys are computerized key fobs that communicate with the vehicle through an embedded antenna to unlock doors and activate the motor. Smart keys, unlike conventional keys that emit the same frequency every time they're used, transmit encrypted signals which are only compatible with the particular car to which they belong to. This makes it harder for thieves with the latest technology to steal or spoof the signal and use the key to steal your car.
For instance, Mercedes' system -known as Keyless Go -- has an internal transponder, which identifies the key of the driver. The Smart Key automatically unlocks and opens the doors and tailgate when it is within 1.5 meters. It also allows you to start the engine by pressing the key.
Furthermore there are smart keys that- like those from BMW have their own user settings that let the driver adjust seat, mirrors and the steering wheel's position as well as audio preferences at the touch of the button. They also come with a backup lock that prevents the vehicle from starting without the key.
This technology assists drivers from locking their vehicles, particularly when fumbling in a purse or backpack for keys in a parking area filled with strangers or on a busy street with high crime rates. Many systems also notify drivers when the key is low on battery, although this feature differs by manufacturer.
Convenience
The smart key is ideal for those in a rush to get somewhere. You can lock, unlock and start your car by pressing a button on the door handle or the trunk release. The key fob will communicate with your phone to keep track of charging, location and other information about the vehicle, according to Popular Mechanics.
You can't accidentally lock your keys in the car. The key fob communicates with the antenna inside the vehicle to determine if it's within range. If it's not, the engine won't not start. This will deter thieves who could steal your vehicle in order to sell the parts.
BMW reports that the smart key makes use of rolling codes as well to stop cloning and hacking. The computer inside the vehicle reads the code and confirms it prior to launching the engine. The majority of systems also have a mechanical backup in the form of an invisible key blade to enhance the appearance of the.
Modern smart keys also detect which key is in use and adjust the vehicle settings accordingly, notes How Stuff Works Electronics. If you switch on the vehicle while holding the key in your palm, for example the windows as well as the sunroof will open to allow air circulation to the interior. You can also set a speed limit which will only be applied when the car is powered by the chosen key. This feature could be useful when you lend your car to a driver who has little experience.
Battery Life
If you're looking for a way to get more mileage out of your vehicle's smart key, or just want to make sure it won't die during a trip to the grocery store, you can activate an auto manufacturer-specific feature called Power Saving Mode. To activate this feature, hold the lock button down and then press the unlock button.
This will make it impossible for your smart key fob from having to send or receive any radio waves. This will significantly increase the battery's life. You can reactivate this feature by pressing the unlock and lock buttons once more.
Certain smart keys also have anti-theft capabilities that protect them from being copied by thieves. Mercedes-Benz smart keys utilize rolling codes to block unauthorised access. When a smart key is inserted into ignition, a computer within the car validates the code in milliseconds prior to beginning the engine. BMW uses a Display Key that has a tiny LCD color screen. This allows drivers to lock their cars, unlock their doors, and start them without taking the smart key from their pocket.

Special Cases
While smart keys are not theft-proof, they do help to discourage thieves. Smart keys use rolling security codes to protect against hacking, and when placed in the ignition, the car's computer can verify the code within milliseconds. This technology was developed by Mercedes-Benz and is now utilized by many automobile brands that are luxury.
A smart key system will work even if you don't remember the key in your trunk or leave it in the restaurant. Certain systems will also notify the driver if the battery is not fully charged. Certain brands also offer keys with covers specifically designed for smart keys, to shield the fob from damage.
