Vehicle Smart Key Technology The smart key technology that is found in automobiles allows drivers to open and start their car by just touching the door handle, or by putting the key into the pocket. It also permits a variety of other adjustments, including seat position the internal temperature setting and mirror position. However, this could create security concerns. Security Smart keys are key fobs that are computerized which communicate with the vehicle through an embedded antenna. It can unlock doors and begin the motor. Unlike conventional keys, which emit the identical frequency signal each time they are pressed, smart key fobs transmit encrypted signals that are specific to the specific car they belong to. This makes it difficult for tech-savvy thieves to spoof or intercept the signal and use the key to steal your car. Mercedes' Keyless Go system for instance, comes with an internal transponder, which can identify the driver's keys. When the Smart Key comes within 1.5 meters of a vehicle, it automatically unlocks the tailgate and door, and the engine starts when a button on the key is pressed. Furthermore there are smart keys that- like those from BMW have their own user settings that let the driver adjust seat, mirrors and steering wheel position and audio preferences at the touch of the button. They also have the backup lock, which stops the vehicle from running without the key. This technology helps drivers avoid getting their car locked accidentally, especially when searching in a purse or a backpack for keys in an open parking lot with people who are not familiar with the area or where crime is high. Many systems will also alert motorists when the battery for their key is depleted, though this feature may differ from manufacturer to the manufacturer. Convenience If you're in a hurry to get somewhere 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 lock, unlock and start your vehicle. Key fobs can also connect to your phone to keep track of charging, location and other information about the vehicle, says Popular Mechanics. A major benefit is that you aren't able to accidentally get locked out. The key fob connects to an antenna in the vehicle to determine if it's within the range. If it's not, the engine will not start. This will stop thieves from absconding with your vehicle and selling parts of it. BMW reports that the smart key employs rolling codes, as well as to ward off hacking and cloning. The computer inside the vehicle recognizes the code and verifies it prior to launching the engine. Most systems also have a mechanical backup in the form of an invisible key blade to serve as a styling tool. Modern smart keys also know which keys are in use and adjust the settings of the vehicle as needed, according to How Stuff Works Electronics. If you turn on your vehicle while holding the key in your palm for instance the windows as well as the sunroof will open to allow air circulation to the interior. You can also set up a speed limit which will only be used when the vehicle is powered by the specified key. This feature can be useful if you're loaning your vehicle to a person who has no prior 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 it, press down the lock button and press the unlock button. This will block your smart key fob from transmitting or receiving radio signals and will increase the battery's life by a significant amount. You can always restart this function by pressing the unlock and lock buttons again. Certain smart keys come with anti-theft features to prevent them from being stolen by thieves. Mercedes-Benz smart key uses rolling codes to stop unauthorized access. The computer in the car examines the code in milliseconds after the smart key is introduced. BMW makes use of a Display Key that has a tiny LCD color screen. This allows drivers to lock their vehicles, unlock them, and even start them without taking the smart key from their pockets.
