What You Should Know About Smart Keys Smart keys – sometimes called digital keys or information keys let drivers access their vehicles without fumbling with a keyhole. Certain cars come with them as standard features, while others offer them as an upgrade option. The technology is also more advanced than a standard key fob. Some systems let you start the vehicle without the traditional key fob or even an actual key. The best models also have indicators for the battery that warn you in advance when the battery is about to expire. Security Smart keys are a lot more useful than traditional keys as they have added security and safety features. They make use of radio-frequency identification or RFID, to communicate with your car's computer. An antenna on your car detects the signal from the key when it's within distance, allowing you unlock your doors and start your engine without needing to pull out your phone or press the button. smart forfour key programming may seem like an excellent feature. However, thieves can penetrate this system and unlock your doors or even start the engine. Certain manufacturers employ a method called “rolling codes” which prevent this from occurring. This code is projected by the key onto the starter and later verified by the computer in the car prior to it starting. This prevents thieves creating multiple copies of the keys. Another way to keep your car secure is to make sure that you don't place your mobile phone and key in the same pocket. Putting the two devices too close together can block the signals, thus preventing them from communicating properly. The KeySmart Pro is a great option to do this since it comes with a built-in Tile that lets you locate your phone. If you have the application installed on your iPhone and place the Smart Key near it, a press of its activation button causes the Tile to emit an unintentional melody and flash an LED. This could be lifesaving when you've lost your phone or it's in silent mode. Convenience Smart keys can be used to store and recall personalized settings including seat, mirror and steering wheel position. Certain smart keys, like BMW's Comfort Access system, allow you to start the vehicle without having to press the ignition button. Modern smart keys utilize radio waves to communicate with antennas inside the car, sending an encrypted signal that is interpreted by the car's computer. The signals can be reprogrammed for different functions, including opening and closing the trunk or activating a child's lock. The technology isn't 100% secure. It's possible for tech-savvy thieves to detect the frequency transmission of an intelligent key and get its unique identification number. Fortunately, manufacturers are trying to improve the security of the system. Another benefit is the ability to remotely lock or unlock your vehicle by tapping of the phone's screen. This feature can help you save time when loading cargo or children. It's particularly useful for parents of teenagers who are learning to drive. One of the best aspects of a smart key is its sleek slim design. This makes it much easier to carry than other key organizers, which are bulky and take up more space than necessary. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle which can make you shiver. Battery Life Smart keys generally last just half as long (two to three years, versus four to six years) as regular fobs. This is because smart keys communicate with the car more often and at a higher rate to unlock and turn it on. Smart keys also consume more energy when put close to electronic devices that generate electromagnetic fields, such as phones, computers and screens. Fortunately, all smart keys have battery backup functions. According to Open Road Auto Group most smart keys have blades that can be used as a traditional key for doors in the event the battery of the smart key fob dies. Most have a slot that the traditional key can be put in to start the engine in the event that the smart key fob is not functioning or is dead. A “power saving mode” is a different smart key backup. If you forget your smart key while driving, your vehicle will continue to run until it is not in operation. To achieve this, you need to place the smart key flat against the steering column of your vehicle while pressing the ignition button once. If you've done it correctly, the system should notify the driver that it is low on the key, but still functioning. Cost While many car owners are switching to smart keys for convenience and added security It's important to remember that the cost of these features isn't always low. If you lose a smart key it could cost you a fortune to replace it and then reprogramme your vehicle. Smart keys look similar to regular keys, however they have a microchip that allows you to unlock, lock or start a vehicle without a physical key. The chip transmits a unique code to the vehicle system, which recognizes and validates the code prior to beginning the engine. This technology has been around for some time however it's not perfect. This technique has been employed by thieves to steal cars in a variety of cases. There are ways to stop this from happening. One method to avoid this is by using the smart key which has rolling security codes. The code changes every time the key is sent. A key fob with an LCD screen can be very expensive. BMW's Display Key, a smart key of this type, is a good example. Its LCD color screen performs all the functions of a standard key fob, such as locking the door, unlocking it, and keyless start. But it can also communicate with the vehicle through an iPhone. This makes it much easier to operate the vehicle and keep an eye on charging and location. It can even instruct the vehicle to park itself this is a fantastic feature for people with limited mobility or disabilities.
