Vehicle Smart Key Technology The technology of smart keys in vehicles enables drivers to unlock and start their car by just touching the door handle, or placing the key into the pocket. It also permits a variety of other adjustments, including seat positions as well as internal temperature settings mirror positioning and stereo presets. However, it could also lead to security concerns. Security Smart keys are electronic keys that communicate with vehicles via one of the antennas that are embedded in the vehicle to open the doors and start the engine. Unlike conventional keys, which emit the same frequency signal each time they are activated, smart keys transmit encrypted signals that are specific to the specific vehicle they belong to. This makes it harder for tech-savvy thieves to fake or intercept the signal and use the key to steal your car. For example, Mercedes' system — called Keyless Go — has an internal transponder, which identifies the key of the driver. When the Smart Key comes within 1.5 meters of a car, it automatically unlocks the door and tailgate and starts the engine when the key's button is press. Furthermore certain smart keyslike those made by BMW have their own user settings that let the driver alter the seat, mirrors, the steering wheel's position and audio preferences at the push of a button. They also come with a backup lock, which prevents the vehicle from starting if the key is not in the ignition. This technology prevents drivers from being unable to lock their vehicle, especially when searching in the bag or purse for keys in a parking lot with strangers or on a busy street where crime is high. Many systems will also alert drivers if the key battery is depleted, though this feature varies by manufacturer. Convenience The smart key is perfect for those trying to get to their destination. By pressing the button on your trunk release lever or door handle, you can open, lock and begin your vehicle. Popular Mechanics explains that the key fob can also be used to monitor charging location, charging status, and other vehicle information. A big benefit is that you aren't able to accidentally lose your keys. The key fob communicates with an antenna inside the vehicle to determine if it's within range. If it's not, the engine will not start. This will deter thieves from the vehicle and stealing parts of it. The smart key also uses rolling codes to protect against hacking attempts and cloning, according to BMW. A computer in the vehicle is able to recognize the code and verifies it before starting the engine. A majority of systems also have a mechanical backup in the form of an invisible key blade to be used for styling purposes. Modern smart keys also know the type of key being used and adjust the car settings in accordance with the key's use, according to How Stuff Works Electronics. For example, if you turn on the car holding the key fob in the palm of your hand, the windows and sunroof can be opened to let the cabin air dry. You can also set a speed limit that will only be in effect when the car is started with the selected key, a feature that could be useful when loaning your car to an inexperienced 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, hold the lock button until you release it and press the unlock button. This will disable your smart key fob from transmitting or receiving any radio waves which will increase its battery's life considerably. You can always reactivate the function by pressing both the lock and unlock buttons again. Certain smart keys come with anti-theft capabilities that prevent them from being stolen by thieves. Mercedes-Benz smart keys employ rolling codes to prevent access by anyone who is not authorized to use it. When the smart key is inserted in the ignition, a computer within the car validates the code in milliseconds prior to beginning the engine. BMW uses a similar method with its Display Key, which includes a small LCD color touchscreen on the smart key for convenience, and allows drivers to lock or unlock their cars without ever removing it from their pockets.
