What You Should Know About Smart Keys Smart keys, also known as keys that are digital or information keys enable drivers to get into their vehicle without having to fiddle with a traditional keyhole. Some vehicles have them as standard features, while others allow them to be upgraded. The technology is also more modern than a traditional fob. Certain systems let you start your car without the traditional key fob, or even an actual key. The most reliable systems also have indicator lights for batteries that notify you when the battery is low. Security Smart keys are more convenient than traditional fobs and also come with additional security and safety features. They communicate with the computer system of your car by using radio-frequency identification (RFID). An antenna in your car will detect the signal of the key when it's in range, allowing you to unlock your doors and start the engine without needing to pull out your phone or press the button. Although this might sound like a convenient feature however, car thieves can hack into the system to unlock your doors and start the engine. Some manufacturers use a technology known as “rolling codes” to prevent this from occurring. The code is projected by the key onto the starter, and then verified by the computer of the car prior to it starting. This is to prevent thieves from creating multiple copies of the keys. Another method to keep your car secure is to make sure that you do not place the key and mobile phone in the same pocket. The two devices placed too close together could block signals, which can stop them from communicating correctly. The KeySmart Pro has a built in Tile that helps you locate your phone. If you have the application installed on your iPhone and you put the Smart Key near it, the press of its activation button triggers the Tile to emit short melodies and flash an LED. This can be a lifesaver in case you've lost your phone in a dark place or even if it's in silent mode. Convenience In addition to locking and unlocking your vehicle smart keys can also store and recall individual settings, such as seat, mirror and steering wheel positioning. Certain smart keys, like BMW's Comfort Access system, allow you to start your car without pressing the ignition button. Modern smart keys communicate with car's antennas through radio waves. They transmit a unique encrypted message that is interpreted and acted upon by the computer. These signals can be programmed to perform various functions such as opening and closing the trunk or activating an electronic child 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 striving to improve the security of the system. Another great feature is the ability to remotely lock or unlock your vehicle using a simple tap of the phone's screen. This feature will save you time when loading cargo or children. It's particularly helpful for parents of teenagers who are learning to drive. The sleek, compact design of a smartkey is one of its greatest features. This makes it much easier to carry than other key organizers that are bulky and take up more space than they need. The KeySmart is also quiet and comfortable to carry, and eliminates the annoying jingle that could make you shiver. Battery Life Smart keys generally last about half the time (two to three years versus four to six years) as traditional fobs. Smart keys need to communicate with the car at a much higher frequency and at a higher frequency to unlock and start the car. Smart keys also drain faster when placed near electronic devices that produce 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 a blade that can be used as a traditional key for doors in the event 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 not functioning. Another feature that smart keys offer is referred to as an “power saving mode.” If you forget to bring your smart key while driving, you can still drive your car as long as the engine isn't running. To accomplish smart car key programming , you need to place the smart key flatly against the steering column of your vehicle while pressing the ignition button one time. If you've done this correctly, your system should inform the driver that the key is in use but it is still functional. Cost While many vehicle owners are upgrading to smart keys for convenience and increased security However, it's important to realize that these features aren't cheap. It can be expensive to replace the lost smart keys and reprogram your car. Smart keys look like regular keys, but they contain a microchip, which allows you to unlock, lock or start a car without having a physical key. The chip transmits an unique code to the vehicle's system, which detects and validates the code prior to starting the engine. This technology has been around for some time, but it's not yet perfect. There have been numerous instances of thieves taking vehicles using this method. There are ways to stop this from happening. One option is to utilize an intelligent key with rolling security codes that alters the code each time it's sent. A key fob that has a display screen is also very expensive. BMW's Display Key, a smart key of this kind is a good example. Its LCD color screen serves all the functions of a typical key fob, like locking the door, unlocking it, and keyless start. However, it is also able to transmit commands to the vehicle using smartphones. This makes it easier to operate the vehicle, and also keep on top of its charging status and the location of its battery. It can even command the car to park itself. This is a great feature for those with handicaps or mobility issues.
