Why Smart Car Key Programming Is Much More Hazardous Than You Think
Vehicle Smart Key Technology
Smart keys in vehicles allow the driver to unlock and start the car simply by pressing the door handle or putting the key in the pocket. It also allows various other adjustments, including seat position as well as internal temperature settings and mirror position.
This could also raise security concerns.
Security
Smart keys are electronic keys that communicate with the vehicle using one of the antennas that are embedded in the vehicle to open doors and to start the engine. Smart key fobs, in contrast to traditional keys, which emit the same frequency each time they're used, transmit encrypted signals which are only compatible with the vehicle to which they belong to. This makes it harder for criminals with a technological edge to intercept or fake the signal, and use your key to steal your car.
For example, Mercedes' system -known as Keyless Go -- has an internal transponder which can identify the key of the driver. The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also turns on the engine by pressing a button on its key.
Additionally certain smart keys- like those from BMW -- have individual user settings that let the driver adjust the mirrors, seat and the steering wheel's position as well as audio preferences with the click of the button. They also have a backup lock that prevents the vehicle from running without the key.
This technology helps keep drivers from locking their cars, especially when they are rummaging through their purses or backpack to locate keys in a parking lot packed with strangers or on a busy street with high rates of crime. Many systems also notify drivers when their keys are low on battery, although this feature is dependent on the manufacturer.
Convenience
The smart key is ideal for those who are in a hurry to get to their destination. By pressing the button on the trunk release or door handle, you can unlock, lock and open your vehicle. The key fob will also connect to your phone to keep track of charging, location and other information about the vehicle, says Popular Mechanics.
You shouldn't lock your keys in the car. The key fob communicates with an antenna inside the vehicle to determine if the key is in range. If it's not, the engine will not start. This will stop thieves from the vehicle and stealing its parts.
BMW reports that the smart key makes use of rolling codes to ward off hacking and cloning. A computer within the vehicle reads the code and confirms it prior to launching the engine. A majority of systems also have a mechanical backup that is an invisible key blade to be used for styling purposes.
Modern smart keys can also tell which keys are in use and adjust the vehicle settings accordingly, notes How Stuff Works Electronics. For instance, if you start the car while holding the key fob in the palm of your hand the windows and sunroof can be opened to let air circulate through the cabin. You can also set the speed limit which will only be in effect when the car is started using the chosen key, which could be useful if you loan your car to a novice driver.
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 do this simply press and hold the lock button while pressing the unlock button.
This will make it impossible for your smart key fob to transmit or receive radio waves. This will dramatically extend the life of your battery. You can always restart this function by pressing the unlock and lock buttons again.
Some smart key s include anti-theft features to prevent them from being stolen by thieves. For instance, Mercedes-Benz smart keys use rolling codes to block unauthorised vehicle access. When a smart key is inserted in the ignition, a computer in the car confirms the code in milliseconds before beginning the engine. BMW makes use of a Display Key that has a small LCD color screen. This allows drivers to lock their cars, open them, and even start them without taking the smart key from their pocket.

Special Cases
Although smart keys aren't security-wise, they can be used to deter thieves. Smart keys employ rolling security codes that prevent hackers, and when put in the ignition, the car's computer checks the code in milliseconds. Mercedes-Benz developed this technology, which is currently used by luxury car manufacturers.
A smart key system will continue to work even if it is not possible to remember the key in the trunk or leave it at an establishment. Certain systems will also inform the driver when the battery is running low. Certain brands provide key covers designed specifically for smart keys, to shield the fob from damage.
