What You Should Know About Smart Keys Smart keys, also referred to as digital keys or information key enable drivers to get into their vehicle without the need to use the traditional keyhole. Some vehicles come with them as standard features, while others offer them as an upgrade option. The technology is far more advanced than the traditional key fob, too. Certain systems let you start your car without the traditional key fob, or even an actual key. The most effective ones also have battery indicators that notify you in advance when the battery is about to run out. Security Smart keys are more practical than traditional keys and also come with additional security and safety features. They communicate with the computer system in your car by using radio-frequency identification (RFID). An antenna on your car will detect the signal of the key when it's within distance, allowing you unlock your doors and start your engine without having to pull out your phone or press a button. While this may sound like a great idea, car thieves can also 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 by the key onto the starter, and then verified by the computer of the car prior to its start. This helps prevent thieves from making multiple copies of the keys. Another way to ensure that your vehicle secure is to ensure that you don't put 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 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 app installed and press the activation button, it will cause the Tile to play a brief tune and flash an LED. This is a lifesaver when you've lost your phone in a dark space or even when it is in silent mode. Convenience Smart keys are able to store and remember personal settings like seat, mirror and steering wheel settings. Certain smart keys, like BMW's Comfort Access system, allow you to start the car without pressing the ignition button. Modern smart keys utilize radio waves to communicate with antennas within the car. They transmit an encrypted signal that is then interpreted by the car's computer. These signals can be reprogrammed to perform different functions like opening and closing the trunk or engaging the child lock. This technology is not foolproof However, it is not foolproof. Cybercriminals with the right skills can steal the unique identification number of a smartkey through the frequency of its transmission. Fortunately, manufacturers have been striving to increase 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 especially helpful when you have teenagers who are learning to drive. One of the best aspects of a smart key is its sleek and compact design. This makes it easier to carry than other key organizers which can be 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 that annoying jingle that can make you shiver. Battery Life Typically smart keys last only half as long as regular fobs with key blades (two to three years versus four to six). Smart keys need to communicate with the car at a faster rate and more frequently to unlock and start the car. Smart keys also consume more energy when placed close to electronic devices that generate electromagnetic fields such as phones, computers, and screens. The majority of smart keys have batteries backup options. According to smart car key coding G28 come with a blade that can be used as a traditional key for doors in the event that the battery of the smart key fob fails. They also have a slot where you can insert an old-fashioned key to turn on the engine if the smart key is dead or not functioning. Another smart key backup feature is called an “power saving mode.” If you don't remember to carry your smart key with you while driving, you can still drive your vehicle 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 will inform the driver that the key is depleted but it is still functional. Cost Many car owners are switching to smart keys for greater convenience and increased security It's important to remember that the cost of these features isn't always low. It can be costly to replace a lost smart key and reprogram your car. Smart keys appear like regular keys, however they contain a microchip which can unlock, lock or start a car without having a physical key. The chip transmits a unique number of digits to the vehicle's system, which recognizes it and validates it prior to starting the engine. This technology has been around for a while, however it is not perfect. There have been a few instances of thieves taking vehicles using this method. There are ways to prevent this from occurring. One method to avoid this is by using the smart key which has rolling security codes. The code is changed each time the key is sent. A key fob with display screens can be extremely expensive. BMW's Display Key is an example of this kind of smart key. Its LCD color screen performs all the functions that are found on a standard key fob like locking, unlocking, and keyless start. However, it can also communicate with the vehicle through a smartphone. This makes it easier to operate the vehicle and keep the track of charging locations and battery levels. It can even instruct the vehicle to park itself. This is a fantastic feature for people with physical limitations or disabilities.
