What You Should Know About Smart Keys Smart keys, also referred to as keys that are digital or information keys, allow drivers to access their vehicle without the need to use the traditional keyhole. Certain vehicles have them as standard features, while others offer them as an upgrade option. The technology is also more advanced than a traditional key fob. Some systems let you start your car without the traditional key fob or even a key. The most reliable systems also have battery indicators which warn you when the battery is low. Security Smart keys are a lot more practical than traditional key fobs as they have additional security and safety features. They utilize radio-frequency identification or RFID, to communicate with your car's computer. If the key is within the range of the antenna it is able to unlock the doors and start the car without needing to use your mobile or push the button. While this may sound like a useful feature but car thieves are also able to hack into the system to open your doors and start the engine. Some manufacturers employ a process known as “rolling codes” to prevent this from happening. The code is projected from the key to the starter and then verified by the computer in the car prior to beginning. This prevents thieves from creating multiple copies of the key. Another way to ensure that your car secure is to make sure that you don't place the mobile phone and the key in the same pocket. Signals can be blocked if the two devices are close. The KeySmart Pro is a great option to do this since it comes with a built-in Tile which helps you find your phone. When you place the Smart Key next to your iPhone with the application installed when you press the activation key, 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 or it's on silent mode. Convenience Smart keys can be used to store and remember personal settings including seat, mirror, and steering wheel positions. Some, like BMW's Comfort Access, even allow you to start your car without having press the ignition button. Modern smart keys communicate with the car's antennas by using radio waves. They send a unique encrypted message that is read and acted upon by the computer. These signals can be reprogrammed to perform different tasks, such as opening and closing the trunk or engaging locks for children. The technology isn't 100% secure. Hackers with technical expertise can get the unique identification number of a smartkey by picking up the frequency of its transmission. Fortunately, the manufacturers have been working to improve the security of the system. Another great feature is the ability to remotely lock and unlock your vehicle using a simple tap of the phone's screen. This feature will save you time when loading cargo or children. It's particularly useful in the case of teens who are learning to drive. The sleek slim design of the smartkey is among its most appealing features. It's easier to carry compared to other key organizers that can be large and take up more room than is necessary. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle that could drive you crazy. Battery Life Typically smart keys last for half as long as regular fobs with key blades (two to three years, versus four to six). This is because the smart keys have to communicate with the car more frequently and at a higher speed to unlock and turn it on. Smart keys also drain faster when put near electronic devices that generate electromagnetic fields like phones, computers and screens. The majority of smart keys have battery backup options. According to Open Road Auto Group most smart keys have blades 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 the traditional key to turn on the engine if the smart key is not functioning. Another smart key backup feature is called the “power saving mode.” If you forget to bring your smart key with you while driving, you are able to drive your car for as long as the engine isn't running. To do this, place the smart key flat on the steering column while pressing the ignition button. If you have done this correctly, your system should notify the driver that the key is depleted but it's still functioning. Cost While many vehicle owners are switching to smart keys for greater convenience and security However, it's important to realize that these features aren't always cheap. It can be expensive to replace an unusable smart key and reprogram your car. Smart keys are similar to regular keys, but have the capability of a microchip to unlock, lock, or start vehicles without the use of physically inserted keys. The chip transmits an unique code to the vehicle's system, which detects and validates the key before beginning the engine. This technology has been around for a while, however it isn't completely the perfect solution. This method has been used by thieves to rob vehicles in a variety of cases. There are ways to stop this from occurring. One method is to use an intelligent key with rolling security codes, which alters the code every time it's transmitted. smart car key replacement G28 Car Keys that has an LCD screen is very expensive. BMW's Display Key is an example of this kind of smart key. Its color LCD touchscreen can perform the standard functions of a keyfob such as locking, unlocking and keyless start but it also send commands from an iPhone to the vehicle's systems. This makes it easier to operate the vehicle and keep the track of charging and location. It can even instruct the car to park itself. This is a great feature if you have handicaps or mobility issues.
