What You Should Know About Smart Keys Smart keys, also known as digital keys or information key can allow drivers to gain access to their vehicle without the need to use traditional keyholes. Some vehicles have them as standard equipment, while others offer them for upgrade. The technology is much more advanced than the traditional key fob too. Some systems let you start your vehicle without the traditional key fob, or even an actual key. The most effective models also have indicators for the battery that alert you in advance when the battery is about to expire. Security Smart keys are a lot more convenient than traditional key fobs, and they come with added security and safety features. They make use of radio-frequency identification or RFID, to communicate with the computer system in your car. An antenna mounted on your car will detect the signal of the key when it is in distance, allowing you unlock your doors and start the engine without having to pull out your phone or press a button. This may seem like an easy feature. However, car thieves are able to penetrate this system and open your doors, or even start the engine. Certain manufacturers use “rolling code” technology to stop this. This code is projected from the key to the starter and verified by the car's computer prior starting. This stops thieves from creating multiple copies of keys. Another way to ensure that your car secure is to ensure that you don't place the mobile phone and the key in the same pocket. Putting the two devices too close could block signals, preventing them from communicating properly. The KeySmart Pro is a great option because it comes with a built-in Tile that helps to 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 is a lifesaver in the event that you lose your phone in a dark space or even when it is on silent mode. Convenience Smart keys can be used to store and remember personal settings like mirror, seat and steering wheel positions. Some, such as BMW's Comfort Access, even allow you to start your car without having hit the ignition button. Modern smart keys utilize radio waves to communicate with antennas inside the car. They transmit an encrypted signal that is interpreted by the car's computer. These signals can be reprogrammed for different functions, including opening and closing the trunk, or activating the child's lock. This technology is not foolproof. Cybercriminals with the right skills can steal the unique identification number of the smartkey, by spotting the frequency of its transmission. Fortunately, companies have been striving to increase the security of the system. An important feature is the ability to remotely lock and unlock your vehicle by pressing the screen of your phone. This will save time when loading children or cargo. This can be especially beneficial if you're an adult with teenagers who are still learning to drive. One of the best aspects of a smart key is its sleek and compact design. It's easier to carry than other key organizers that can be heavy and take up more space than is necessary. The KeySmart is quiet and easy to use, removing that annoying jingle. Battery Life Typically smart keys last just half the time as regular fobs that have key blades (two to three years versus four to six). This is because smart keys need to communicate with the car more often and at a higher rate to unlock it and start it. Smart keys also drain faster when put close to electronic devices that generate electromagnetic fields such as screens, computers and phones. The majority of smart keys have batteries backup options. According to Open Road Auto Group, they come with an emergency blade that functions as an old-fashioned key to open the door of the driver in case the smart key fob batteries die. Most have a slot that a traditional key can be put in to start the engine in the event that the smart key fob isn't functioning or is dead. Another smart key backup feature is known as a “power saving mode.” If you don't remember to carry your smart key while driving, you'll be able to drive your vehicle for as long as the engine isn't running. To accomplish this, you should place the smart key flatly against the steering column of your vehicle while pressing the ignition button once. If you have done this correctly, your system will notify the driver that the key is not working but it is still functional. Cost Smart keys aren't always cheap. Many car owners upgrade their keys to smart ones to enhance security and convenience. It can be costly to replace a lost smart key and reprogram your car. Smart keys look similar to normal key fobs, however they contain a microchip, which can unlock, lock or start a car without having a physical key. The chip transmits a unique code to the vehicle's computer system, which recognizes it and verifies it before beginning the engine. This technology has been in use for a while but it's not perfect. There have been numerous instances of thieves stealing vehicles using this method. There are ways to prevent this from occurring. One method to stop this is by using an electronic key that contains rolling security codes. The code is changed each time the key is sent. A key fob with a display screen is also extremely expensive. BMW's Display Key is an example of this kind of smart key. smart car key fob can perform the usual functions of a key fob such as locking, unlocking and keyless start, but it can also transmit commands from a smartphone to the systems of the vehicle. This makes it much easier to operate the vehicle and keep an eye on charging and location. It can even instruct the car to park itself. This is a great feature if you have physical limitations or disabilities.
