Vehicle Smart Key Technology
The smart key technology in vehicles allows a driver to unlock and start the car by pressing the door handle or putting the key in the pocket. It also permits a variety of other adjustments such as the position of the seat, internal temperature settings and mirror positioning.
This can also cause security worries.
Security
Smart keys are advanced computerized key fobs that communicate with a vehicle via one of the antennas in the car to open the doors and smart car keys begin the engine. In contrast to conventional keys that emit the identical frequency signal each time they are used, smart keys transmit encrypted signals that are only compatible with the specific car they belong to. This makes it much more difficult for tech-savvy criminals to intercept or spoof the signal, and then use your key to steal your vehicle.

Furthermore certain smart keys- like those from BMW have their own user settings that let the driver adjust the seat, mirrors and the steering wheel’s position and audio preferences at the click of one button. They also have a backup lock that blocks the vehicle from starting if it is not connected to the key.
This technology prevents drivers from accidentally locking their cars, particularly when fumbling in a purse or backpack to locate keys in a parking area filled with strangers or on a busy street with high rates of crime. Many systems will also alert drivers when the battery of their key is low, though this feature may differ from manufacturer to the manufacturer.
Convenience
If you’re in a hurry to get to a place, the smart key makes entering your vehicle as easy as it can be. By pressing the button on the trunk release or door handle, you can open, lock and begin your vehicle. Popular Mechanics explains that the key fob can also be used for tracking charging, location, and other information about your vehicle.
A big benefit is that you don’t lock yourself out. The key fob communicates with the antenna inside the vehicle to determine if it’s within range. If it’s not, the engine will not start. This will stop thieves from taking your vehicle and then selling parts of it.
The smart key also makes use of rolling codes to prevent hacking attempts and cloning, says BMW. The computer in the vehicle recognizes and verifies the code prior to launching the motor. Many systems also have a mechanical backup that is an unnoticed key blade to be used for styling purposes.

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, hold down the lock button and press the unlock button.
This will stop your smart key fob’s smart device from being able to send or receive any radio waves. This will significantly extend the life of its battery. You can always restart this feature by pressing the unlock and lock buttons again.
Some smart keys include anti-theft functions that prevent them being copied by thieves. Mercedes-Benz smart keys use rolling codes to stop the unauthorized access. The computer in the car will check the code every millisecond after the smart key is introduced. BMW uses a Display Key with a small LCD color screen.

Another useful feature is that many smart key systems will continue to function even if the user has forgotten the key in the trunk or left it at the restaurant or if it is lost on hiking. Some systems will alert the driver when the battery is not fully charged. Certain brands provide key covers specifically made for smart keys that keep the key safe from damage.
