Smart keys for vehicles allow drivers to unlock and start the car by touching the door handle or placing the key in the pocket. It also permits various other adjustments including seat position, internal temperature settings and mirror positioning.

Security
Smart keys are computerized key fobs that communicate with vehicles through an embedded antenna. It can unlock doors and activate the motor. In contrast to conventional keys that emit the identical frequency signal each time they are pressed, smart key fobs transmit encrypted signals that only match the car they belong to. This makes it more difficult for thieves with a technological edge to impersonate or intercept the signal and use the key to take your car.
For instance, Mercedes' system -known as Keyless Go -- has an internal transponder that identifies the driver's keys. The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also starts the engine by pressing the key.
Additionally certain smart keyssuch as those from BMW have their own user settings that let the driver adjust the seat, mirrors and the position of the steering wheel as well as audio preferences at the touch of the button. They also have a backup lock that prevents the vehicle starting without the key.
This technology helps drivers avoid being unable to lock their vehicle especially when looking in a purse or a backpack for keys on an open parking lot with strangers, or on a street where crime is high. Many systems will also inform drivers if the key battery is low, though this feature varies from manufacturer the manufacturer.
Convenience
The smart key is perfect for those on the move and need to get somewhere. You can lock, unlock and start your car by pressing a button on the door handle or trunk release. Popular Mechanics explains that the key fob can also be used to monitor charging location, charging status, and other information about your vehicle.
You can't accidentally lock your keys inside the car. The key fob is connected to an antenna inside the vehicle to determine if it's within the range. If not, the engine will not start. This can deter thieves who may steal your car to sell its parts.
The smart key also employs rolling codes to deter hacking attempts and cloning, says BMW. A computer in the vehicle recognizes the code and confirms it before starting the engine. Most systems have a mechanical backup system in the form of an unnoticed key blade.
How Stuff Works Electronics notes that modern smart key s also detect the key used and adjust the car settings in line with the use of the key. If you turn on the vehicle while holding the key in your palm, for example the windows as well as the sunroof can be opened to allow fresh air to enter the interior.

This feature can be beneficial if you're lending your vehicle to a driver who has no prior 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 activate it, hold the lock button, then press the unlock button.
This will stop your smart key fob's smart chip from sending or receiving radio waves which will increase its battery's life by a significant amount. It is possible to reactivate the function by pressing the unlock and lock buttons again.
Some smart keys also have anti-theft capabilities that protect them from being copied by thieves. For instance, Mercedes-Benz smart keys use rolling codes to prevent unauthorized vehicle access. The car's computer examines the code in milliseconds after the smart key is introduced. BMW uses a Display Key that has a small LCD screen with a color.
