Smart Car Key Programming Tips That Will Change Your Life
Vehicle Smart Key Technology
The smart key technology that is found in automobiles allows drivers to open and start their vehicle by simply touching the door handle or placing the key into the pocket. It also allows a variety of other adjustments like the position of the seat the internal temperature setting and mirror positioning.
However, it could also create security concerns.
Security
Smart keys are key fobs that are computerized that communicate with vehicles via an embedded antenna. This allows them to unlock doors and start the motor. Smart key fobs, as opposed to traditional keys that emit the same frequency each time they're pressed, send encrypted signals which are only compatible with the vehicle to which they belong. This makes it harder for criminals with a technological edge to intercept or fake the signal and use your key to steal your vehicle.
Mercedes' Keyless Go system for instance, has an internal transponder which identifies the driver's key. The Smart Key automatically unlocks and opens the doors and tailgate when it is within 1.5 meters. It also turns on the engine by pressing a button on its key.
Furthermore, some smart keys -- like those from BMW include individual user settings that allow the driver to adjust the seat, mirrors and steering wheel position and audio preferences at the push of the button. They also have a backup lock that will stop the car from starting if the key is not in the ignition.
This technology assists drivers from locking their cars, particularly when they are rummaging through their purses or backpack to find keys in a parking space packed with strangers or on a busy street with high crime rates. Some systems will also notify motorists when the battery for their key is low, but this feature may differ from manufacturer to the manufacturer.
Convenience

How Stuff Works Electronics notes that modern smart keys also detect the key being used and adjust the vehicle settings according to the situation. If you start the vehicle while holding the key in your hands, for example the windows as well as the sunroof will be opened to let air circulate the interior. You can also set up a speed limit that will only be activated when the car is powered by the specified key. This feature is beneficial if you're lending your vehicle to a driver who is not experienced.
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, hold down the lock button and press the unlock button.
