What You Should Know About Smart Keys Smart keys – also known as digital keys or information keys enable drivers to access their cars without having to look for a keyhole. Certain vehicles include them as standard features, whereas others offer them as an upgrade option. The technology is more advanced than the traditional key fob, as well. Some systems have emergency starting capabilities that let you open the car and start the engine without having a key fob (or even the traditional one). The best systems also have indicators for batteries that alert you when the battery is running low. Security Smart keys are more practical than traditional keys 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 range of the antenna, it can be used to unlock the doors and start the car, without the need to make use of your phone or push a button. This might seem like an easy feature. However, car thieves can hack into this system and open your doors, or even start the engine. Certain manufacturers employ “rolling code” technology to stop this. This 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 keys. You can also ensure your vehicle is secure by not placing the phone and key in the same pocket. The two devices placed too close together can block the signals, preventing them from sending signals correctly. The KeySmart Pro is a great alternative to this as it has a built-in Tile that helps you locate your phone. If you have the app installed on your iPhone and place the Smart Key near it, the press of its activation button causes the Tile to play an elongated melody and flash an LED. smart car key replacement cost G28CarKeys can be extremely helpful if you have lost your phone in a dark place or even if it's in silent mode. Convenience Smart keys can store and recall personal settings like mirror, seat and steering wheel position. Some, like BMW's Comfort Access, even allow you to start your car without having push the ignition button. Modern smart keys communicate with the car's antennas via radio waves. They transmit an encrypted message that is then interpreted and acted upon by the computer. These signals can be reprogrammed to perform various functions for example, opening and closing the trunk, or engaging the child lock. The technology isn't completely foolproof It is, however, not foolproof. It is possible for cybercriminals to recognize the frequency of a smart key and then steal its unique identification number. Fortunately, the manufacturers have been striving to increase the security of the system. Another feature that is useful is the capability to remotely lock and unlock your vehicle by tapping of the phone's screen. This can help you save time when loading children or cargo and can be especially useful if you're an adult with teenagers who are just learning to drive. One of the best features of a smart key is its sleek and compact design. It's easier to carry than other key organizers that can be large and take up more space than necessary. The KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle that could drive you crazy. Battery Life Smart keys typically last just half as long (two to three years) versus four to six years) as regular fobs. This is due to the fact that smart keys have to communicate with the car more often and at a higher rate to unlock it and start it. Smart keys also drain faster when they are placed near electronic devices like phones, computers and screens that generate electromagnetic fields. Fortunately, all smart keys have battery backup features. According to Open Road Auto Group most smart keys come with blades that can be used as a traditional key for doors in the event the battery of the smart key fails. There is also a special slot that lets you insert traditional keys to start the engine if the smart key is not functioning. A “power saving mode” is another smart key backup. If you misplace your smart key while driving, your vehicle will continue to function 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 have done this correctly, the system will notify the driver that it's not in the right place but nonetheless functional. Cost Smart keys are not always affordable. Many vehicle owners upgrade to smart keys to improve security and convenience. It can be costly to replace an unusable smart key and reprogram your vehicle. Smart keys are similar to regular key fobs but include the capability of a microchip to unlock or lock vehicles without the use of the use of a physical key. The chip transmits a unique code to the car's system that recognizes the code and confirms it prior to starting the engine. This technology has been around for some time, but it's not perfect. There have been a few instances of thieves taking vehicles using this method. There are methods to stop this from happening. One way to prevent this is by using a smart key that has rolling security codes. The code changes each time the key is transmitted. A key fob that features a display screen is also 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, such as locking in, unlocking, and keyless start. It can also communicate with the vehicle using an iPhone. This makes it much easier to operate the vehicle and keep an eye on charging and location. It can even command the car to park itself. This is a great feature for people with limitations in mobility or have disabilities.
