Vehicle Smart Key Technology

Smart keys for vehicles allow drivers to open and start the car by grabbing the door handle or placing the key in the pocket. It also allows for many other adjustments like seat position as well as internal temperature settings and mirror positioning.

This can also lead to security concerns.

Security

Smart keys are key fobs that are computerized that communicate with vehicles through an embedded antenna to unlock doors and activate the motor. In contrast to conventional keys that emit the same frequency signal each time they are pressed, smart key fobs transmit encrypted signals that are specific to the car they belong to. This makes it much more difficult for criminals with a technological edge to intercept or spoof the signal, and then use your key to steal your car.

Mercedes' Keyless Go system for instance, has an internal transponder that identifies the driver's key. When the Smart Key comes within 1.5 meters of a car it instantly unlocks the door and tailgate and starts the engine when a button on the key is hit.

Certain smart keys, like those made by BMW are also equipped with user-specific settings, which allow the driver to adjust the seat, mirrors, steering wheel position, and audio preferences with the push of a button. They also have a backup lock that blocks the vehicle starting without the key.

This technology prevents drivers from not locking their cars properly and causing damage to their vehicle, particularly when searching backpacks or purses for keys in parking lots with strangers or on a busy street where crime is high. Many systems will also alert drivers if the key battery is low, but this feature can vary by manufacturer.

Convenience

The smart key is ideal for those who are in a hurry to get to their destination. You can lock, unlock and start your car simply by pressing a button on the door handle or the trunk release.

BMW reports that the smart key makes use of rolling codes in order to ward off hacking and cloning. The computer in the vehicle is able to recognize and verify the code before starting the motor. Most systems also have a backup mechanical system in the form of the key blade, which is hidden to serve as a styling tool.

How Stuff Works Electronics notes that modern smart keys can also detect the keys in use and adjust vehicle settings in line with the use of the key. If you turn on the vehicle while holding the key in your palm, for example windows and the sunroof will be opened to let air circulate the interior. You can also set a speed limit that will only be used when the vehicle is powered by the chosen key. This feature is useful if you're loaning your car to someone with no 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, press and hold the lock button while pressing the unlock button.

This will prevent your smart key fob's smart chip from sending or receiving any radio signals that could extend its battery life significantly. You can always reactivate the function by pressing the unlock and lock button again.

Certain smart keys have anti-theft capabilities that prevent them from being stolen by thieves. Mercedes-Benz smart key uses rolling codes to prevent access by anyone who is not authorized to use it. When a smart key is inserted into the ignition, a computer in the car confirms the code in milliseconds before it starts the engine. BMW also has a similar system with its Display Key, which includes an LCD touchscreen on the smart key for ease of use and lets drivers lock and unlock their cars without ever removing it from their pockets.
