What You Should Know About Smart Keys Smart keys – also known as digital keys or information keys – enable drivers to access their cars without fumbling with a keyhole. Certain vehicles come with them as standard features while others offer them for upgrade. The technology is more advanced than the traditional key fob, as well. Certain systems come with emergency starting capabilities that allow you open the car and start the engine without a key fob (or even an old-fashioned one). The best models also have indicators for the battery that warn you in advance when the battery is about to expire. Security Smart keys are more comfortable than traditional fobs and include additional security and safety features. They connect to the computer system in your car through 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 use a phone or push a button. This could be a convenient feature. However, car thieves are able to get into the system and open your doors, or even start the engine. Some manufacturers use “rolling code” technology to stop this. The code is projected from the key to the starter and then verified by the computer in the car prior to the car starts. This prevents thieves creating multiple copies of the keys. You can also ensure your vehicle is secure by not placing your phone and the key in the same pocket. If you place the two devices too close to each other can block the signals, thus preventing the devices from communicating properly. The KeySmart Pro has a built in Tile that can help you locate your phone. If you have the app installed on your iPhone and you put the Smart Key near it, pressing its activation button causes the Tile to emit a short melody and flash an LED. This could be lifesaving if you've lost your phone, or it's on silent mode. Convenience Smart keys are able to store and retrieve personal settings, like seat, mirror and steering wheel position. Some smart keys, like BMW's Comfort Access system, allow you to start your car without pressing the ignition button. Modern smart keys communicate with the car's antennas by using radio waves. They transmit an encrypted message that is read and acted upon by the computer. These signals can be modified to perform different tasks like opening and closing the trunk or engaging a child lock. smart car key recoding isn't completely foolproof However, it's not completely foolproof. It is possible for thieves with a technological edge to detect the frequency transmission of the smart key and steal its unique identification number. Fortunately, the manufacturers have been working to improve the security of the system. An important feature is that you can remotely lock and unlock your car by tapping the screen of your smartphone. This will save time when loading up your kids or cargo. It can be particularly beneficial if you're parents of teenagers who are just beginning to learn how to drive. The sleek slim design of the smartkey is among its best features. It is much more convenient to carry than other key organizers that can be bulky and take up more space than they need. The KeySmart is quiet and easy to use, removing the annoying jingle. Battery Life Typically smart keys last about just half the time as regular keys with blades (two to three years, versus four to six). This is due to the fact that the smart keys communicate with the car more often and at a higher rate to unlock and turn it on. Smart keys also consume more power when placed near electronic devices that produce electromagnetic fields, such as phones, computers and screens. The majority of smart keys have batteries backup options. According to Open Road Auto Group, most come with an emergency blade that functions as traditional keys to unlock the door of the driver in the event that smart key fob's batteries fail. Most also have a special slot that lets you insert the traditional key to start the engine if the smart key is dead or is not working. Another feature that smart keys offer is referred to as a “power saving mode.” If you forget to take your smart key while driving, you can drive your vehicle as long as the engine isn't running. To do this, 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 it correctly, your system will inform the driver that the key is low but it's still functioning. Cost While many vehicle owners are converting to smart keys for greater convenience and security It's important to remember that these features aren't cheap. If you have lost a smart key it can cost a fortune to replace it and reprogramme your car. Smart keys appear like regular keys, however they contain a microchip which can unlock, lock, or start a car that does not have a physical one. The chip transmits a unique code to the vehicle system, which detects and validates the code prior to starting the engine. This technology has been in use for some time but it's not perfect. This method has been used by thieves to rob vehicles in a variety of cases. The good news is that there are ways to prevent this from happening. One option is to utilize a smart key that has security codes that roll, which alters the code each time it's used. A key fob that has a display screen can also be extremely costly. BMW's Display Key is an example of this kind of smart key. Its LCD color screen serves all the functions of a traditional key fob like locking in, unlocking, and keyless start. However, it can also communicate with the vehicle through a smartphone. This allows you to use the vehicle and keep on top of its charging status and the location of its battery. It can even instruct the vehicle to park itself which is a wonderful feature for people with limited mobility or disabilities.
