What You Should Know About Smart Keys Smart keys – also referred to digital keys or information keys permit drivers to use their vehicles without fumbling around with the keyhole. Some vehicles come with them as standard features, while others allow them to be upgraded. The technology is better than the traditional key fob, as well. Some systems let you start your vehicle without the traditional key fob or even an actual key. The best ones also come with battery indicators that notify you in advance when the battery is about to expire. Security Smart keys are more convenient than traditional fobs and come with additional security and safety features. They communicate with the computer system in your car via radio-frequency identification (RFID). If the key is within the range of the antenna, it can be used to unlock the doors and start the car, without the need to make use of your phone or press the button. While this may seem like a convenient feature but car thieves are also able to hack into the system to open your doors and then start the engine. Some manufacturers use “rolling code” technology to ward off this. This code is projected from the key to the starter, and then verified by the car's computer prior to starting. This stops thieves from creating multiple copies of the keys. Another way to ensure that your vehicle secure is to ensure that you do not place your mobile phone and key in the same pocket. The two devices placed too close together can block the signals, thus preventing them from communicating correctly. The KeySmart Pro has a built in Tile that helps you locate your phone. When you place the Smart Key next to your iPhone with the application installed and press the activation button, it will trigger the Tile to play a short tune and flash an LED. This can be life-saving in the event that you lose your phone in a dark space or even when it is in silent mode. Convenience In addition to locking and unlocking your car, a smart key can also store and recall personal settings such as seat, mirror and steering wheel position. Certain smart keys, such as BMW's Comfort Access system, allow you to start the car without having to touch the ignition button. Modern smart keys use radio waves to communicate with antennas within the car. They transmit an encrypted signal that is read by the car's computer. The signals can be reprogrammed to perform various functions for example, opening and closing the trunk or activating an electronic child lock. This technology is not foolproof. Tech-savvy thieves can intercept the unique identification number of the smartkey by detecting the frequency of its transmission. Thankfully, the manufacturers are striving to improve the security of the system. One of the most useful features is the ability to remotely lock and unlock your car by pressing the screen of your phone. This feature will help you save time when loading cargo or children. It's particularly helpful when you have teenagers who are learning to drive. The sleek compact design of a smartkey is among its best features. This makes it easier to carry than other key organizers that can be heavy and take up a lot more space than they need. The KeySmart is quiet and easy to use, eliminating that annoying jingle. Battery Life Typically, smart keys last only half as long as regular fobs that have key blades (two to three years versus four to six). This is because the smart keys must communicate with the car more often and at a higher rate to unlock it and start it. Smart keys also drain more energy when put close to electronic devices that generate electromagnetic fields like phones, computers and screens. Fortunately, smart key for car come with batteries backup features. According to Open Road Auto Group most smart keys come with blades that can be used as a traditional door key in the event that the battery of the smart key dies. They also have a slot that lets you insert traditional keys to start the engine if the smart key is is not working. Another feature that smart keys offer is called the “power saving mode.” If you do not take your smart key while driving, you can still drive your car as long as the engine isn't running. To do this, simply place the smart key flat on the steering column and press the ignition button. If you've done this correctly, the system should notify the driver that it's low on the key, but still functioning. Cost Although many car owners are switching to smart keys for convenience and increased security It's important to understand that these features can be expensive. It can be costly to replace an unusable smart key and reprogram your car. Smart keys are like regular key fobs but include a microchip that can unlock, lock, or start vehicles without the use of a physical key. The chip transmits a unique code to the vehicle's system, which identifies and validates the code prior starting the engine. This technology has been in use for a while however it's not completely. There have been a few instances of thieves stealing vehicles using this method. The good news is that there are solutions to prevent this from happening. One method to stop this is to use an electronic key that contains rolling security codes. The code changes each time the key is transmitted. A key fob with display screens is very expensive. BMW's Display Key, a smart key of this kind is a good example. Its color LCD screen performs all the functions of a traditional key fob, such as locking or unlocking the key, as well as keyless start. It can also send commands to the vehicle through the smartphone. This makes it easier to operate the vehicle and keep on top of its charging status and the location of its battery. It is also able to command the vehicle to park itself which is a wonderful feature for those with limited mobility or disabilities.
