What You Should Know About Smart Keys Smart keys – sometimes called digital keys or information keys – enable drivers to access their cars without fumbling around with the keyhole. Certain vehicles come with them as standard equipment, while others offer them for upgrade. The technology is much more advanced than the traditional key fob too. Certain systems come with emergency starting capabilities that let you open the car and start the engine without the need for a key fob (or even an old-fashioned one). The best ones also have battery indicators that notify you in advance when the battery is about to expire. Security Smart keys are more efficient than traditional key fobs as they have additional security and safety features. They communicate with the computer system of your car by using radio-frequency identification (RFID). When the key is within range of the antenna it is able to unlock the doors and start the car without needing to make use of your phone or press the button. It may appear to be an easy feature. However, car criminals are able to penetrate this system and unlock your doors and even start the engine. Certain manufacturers employ a technique called “rolling codes” to prevent this from happening. This code is projected from the key to the starter and verified by the car's computer before beginning. This stops thieves from creating multiple copies of keys. Another method to keep your car safe is to ensure that you do not place your mobile phone and key in the same pocket. Signals can be blocked if the two devices are too close together. The KeySmart Pro is a great option to do this since it has a built-in Tile that lets to 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 triggers the Tile to play an elongated melody and flash an LED. This can be a lifesaver in case you've lost your phone in a dark place or even if the phone is in silent mode. Convenience Smart keys are able to store and recall personal settings including seat, mirror and steering wheel position. Certain smart keys, for instance BMW's Comfort Access system, allow you to start your car without having to touch the ignition button. Modern smart keys communicate with the car's antennas through radio waves. They transmit an encrypted message that is read and processed by the computer. The signals can be reprogrammed for various purposes, including opening and closing the trunk, or engaging the lock of a child. This technology is not foolproof. It is possible for cybercriminals to recognize the frequency of an intelligent key and get its unique identification number. Fortunately, manufacturers have been trying to enhance the security of the system. One of the most useful features is that you can remotely lock and unlock your car by tapping the screen of your smartphone. This feature will save you time when loading cargo or children. It's especially helpful when you have teenagers who are learning to drive. The sleek and compact design of the smartkey is one of its most appealing features. It is easier to carry than other key organizers that are bulky and take up more space than they need. The KeySmart is quiet and easy to use, eliminating that annoying jingle. Battery Life Typically smart keys last about less than regular keys with blades (two to three years versus four to six). Smart keys must communicate with the car at a faster frequency and at a higher frequency to unlock and start the car. Smart keys can also be drained faster when placed close to electronic devices such as phones, computers, and screens that emit electromagnetic fields. Fortunately, all smart keys come with battery backup features. According to Open Road Auto Group, most come with an emergency blade that acts as an ordinary key to open the door for the driver in case the smart key fob's batteries fail. The majority of them have a slot in which traditional keys can be put in to start the engine in the event that the smart key fob isn't working or is dead. G28 saving mode” is a different smart key backup. If you misplace your smart key while driving, your car will continue to run regardless of whether it's not running. To do this simply lay the smart key flat on the steering column while pressing the ignition button. If you've done it correctly, your system will notify the driver that the key is not working but is functional. Cost Although many car owners are converting to smart keys for greater convenience and security However, it's important to realize that these features can be expensive. It can be costly to replace the lost smart keys and reprogram your vehicle. Smart keys appear like regular keys, however they have a microchip that can be used 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 starting the engine. This technology has been in use for a while, but isn't completely perfect. This method has been employed by thieves to rob vehicles in various instances. There are methods to stop this from happening. One option is to use a smart key that has rolling security codes that changes the code every time it's transmitted. A key fob with display screens is very expensive. BMW's Display Key is an example of this type of smart key. Its LCD color touchscreen does the basic functions of a keyfob such as locking, unlocking and keyless start but it also transmit commands from smartphones to the vehicle's systems. This allows you to use the vehicle, and also keep track of its charging and location. It can even command the vehicle to park itself this is a fantastic feature for those with limited mobility or disabilities.
