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 vehicles have them as standard features, while others offer them as an upgrade option. The technology is also more advanced than a traditional key fob. Some systems have emergency starting capabilities that allow you open the car and start the engine without a key fob (or even an ordinary one). The most effective ones also have indicators for battery which warn you ahead of time when the battery is about to run out. Security Smart keys are more convenient than traditional fobs and also come with additional security and safety features. They connect to the computer system in your car using radio-frequency identification (RFID). An antenna mounted on your car reads the signal from the key when it is in the range, which allows you to unlock your doors and start your engine without having to pull out your phone or press the button. While this may sound like a convenient feature however, car thieves can hack into the system to unlock your doors and then start the engine. Some manufacturers use “rolling code” technology to prevent this. This code is projected from the key to the starter, and then verified by the car's computer before the car starts. This is to prevent thieves from creating multiple copies of the keys. Another way to keep your vehicle secure is to ensure that you don't put your mobile phone and key in the same pocket. The signals can be blocked when the two devices are close. The KeySmart Pro is a great option for this because it has a built-in Tile that lets you locate your phone. When you place the Smart Key next to your iPhone with the application installed by pressing the activation button, it will trigger the Tile to play a short tune and flash an LED. This could be lifesaving should you lose your phone or if it's on silent mode. Convenience In addition to locking and unlocking your car Smart keys can also save and recall individual settings such as mirror, seat and wheel positions. Some, like BMW's Comfort Access, even allow you to start your vehicle without having to push the ignition button. Modern smart keys utilize radio waves to communicate with antennas within the car, generating a unique encrypted signal that is interpreted by the car's computer. The signals can be reprogrammed to perform various functions, such as opening and closing the trunk, or engaging a child's lock. This technology is not foolproof. Cybercriminals with the right skills can steal the unique identification number of a smartkey by picking up its frequency transmission. Fortunately, manufacturers are trying to improve the security of the system. Another useful feature is the ability to remotely lock or unlock your vehicle by tapping of the phone's screen. This feature will help you save time when loading children or cargo. It's particularly useful when you have teenagers who are learning to drive. The sleek and compact design of the smartkey is among its greatest features. This makes it easier to carry than other key organizers that are heavy 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 drive you crazy. Battery Life Typically, smart keys last less than regular fobs with key blades (two to three years versus four to six). The smart keys must communicate with the vehicle at a greater frequency and more frequently in order to unlock and start the car. Smart keys can also be drained faster when they are located close to electronic devices, such as phones, computers, and screens that produce electromagnetic fields. Fortunately, all smart keys have battery backup features. According to Open Road Auto Group, they come with an emergency blade that functions as a traditional key to open the door for the driver in the event that smart key fob batteries die. There is also a special slot where you can insert an old-fashioned key to turn on the engine if the smart key is dead or is not working. Another feature that smart keys offer is called a “power saving mode.” If you do not take your smart key while driving, you can drive your car as long as the engine is not running. To do this simply lay the smart key flat on the steering column while pressing the ignition button. If you've done this correctly, your system should inform the driver that the key is in use but it's still functioning. Cost While many vehicle owners are switching to smart keys for convenience and added security However, it's important to realize that these features aren't cheap. It can be expensive to replace a lost smart key and reprogram your car. Smart keys resemble regular keys, but they contain a microchip, which can unlock, lock or start a car without a physical one. The chip sends a unique identifier to the vehicle's computer system, which recognizes it and confirms it prior beginning the engine. smart car key programming has been in use for a while, but isn't completely yet perfect. There have been a few instances of thieves stealing cars using this method. There are ways to prevent this from happening. One way to prevent this is to use a smart key that has rolling security codes. The code changes each time the key is transmitted. A key fob with an LCD screen is very expensive. BMW's Display Key is an example of this type of smart key. Its LCD color screen serves all the functions of a typical key fob, like locking, unlocking, and keyless start. However, it is also able to communicate with the vehicle from smartphones. This makes it easier to operate the vehicle and keep track of charging and location. It can even tell the vehicle to park itself this is a fantastic feature for those with limited mobility or disabilities.
