The Reasons Smart Car Key Programming Is More Dangerous Than You Thought
Vehicle Smart Key Technology
Smart keys for vehicles allow a driver to unlock and start the car by touching the door handle or placing the key in the pocket. It also allows a variety of other adjustments including the position of the seat as well as internal temperature settings and mirror position.
However, it could also cause security issues.
Security
Smart keys are computerized key fobs that communicate with the vehicle via an embedded antenna. This allows them to unlock doors and activate the motor. Smart key fobs, as opposed to traditional keys, which emit the same frequency each time they're pressed, send encrypted signals which are only compatible with the specific car to which they belong. This makes it harder for thieves with advanced technology to detect or spoof the signal, and use your key to steal your vehicle.
For instance, Mercedes' system -known as Keyless Go -- has an internal transponder that identifies the driver's key. When the Smart Key comes within 1.5 meters of a vehicle, it automatically unlocks the tailgate and door and the engine will start when a button on the key is pressed.
Additionally certain smart keys- like those from BMW have their own user settings that allow the driver to adjust the mirrors, seat and steering wheel position and audio preferences at the push of the button. They also come with a backup lock that blocks the vehicle from starting without the key.
This technology stops drivers from accidentally locking their vehicles and causing damage to their vehicle, particularly when searching the bag or purse for keys on parking lots with people who are not familiar with the area or where crime is high. Many systems will also alert drivers if the key battery is depleted, though this feature may differ from manufacturer to the manufacturer.
Convenience
The smart key is perfect for those who are in a hurry to get somewhere. By pressing the button on the trunk release lever or door handle, you can open, lock and start your vehicle. Popular Mechanics explains that the key fob can also be used for tracking charging or location as well as other information about your vehicle.
You shouldn't lock your keys in the car. The key fob communicates with an antenna inside the vehicle to determine if it is within range. If it's not, the engine will not start. This will deter thieves who would take your vehicle and sell its parts.
BMW reports that the smart key employs rolling codes, as well as to prevent hacking and cloning. The computer inside the vehicle can recognize and verify the code before starting the motor. Most systems also have a mechanical backup that is an unnoticed key blade to enhance the appearance of the.
Modern smart keys can also tell the key that is being used and adjust the car settings in line with the use of the key, says How Stuff Works Electronics. If you turn on your vehicle while holding the key in your hand, for example windows and the sunroof will be opened to let air circulate the interior. You can also set up an automatic speed limit that will only be activated when the vehicle is powered by the specified key. This feature is useful if you are lending your car to someone with no experience.
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, hold the lock button, then press the unlock button.
This will stop your smart key fob from sending or receiving radio signals and will increase the battery's life by a significant amount. It is possible to reactivate the function by pressing both the unlock and lock buttons again.
Certain smart keys have anti-theft functions that prevent them being stolen by thieves. Mercedes-Benz smart keys utilize rolling codes to stop unauthorized access. When the smart key is put in the ignition, a computer in the car validates the code in milliseconds before beginning the engine. BMW offers a similar system with its Display Key, which features an LCD touchscreen on the smart key to make it easier, and enables drivers to lock or unlock their cars without ever removing it from their pockets.

Special Cases
While smart keys aren't safe from theft, they do assist to hinder thieves. Smart key fobs use rolling security codes to protect against hackers, and when put in the ignition, the car's computer checks the code in milliseconds. Mercedes-Benz invented this technology, which is now used by luxury car manufacturers.
A smart key system will work even if you don't remember the key in the trunk or leave it in the restaurant. Some systems will alert the driver when the battery is running low. Certain brands have key covers specifically made for smart keys that keep the key safe from harm.
