What You Should Know About Smart Keys Smart keys – sometimes called digital keys or information keys – let drivers access their vehicles without fumbling with a keyhole. Some vehicles have them as standard equipment, while others have them available for upgrade. The technology is also more advanced than a traditional key fob. Some systems let you start the vehicle without the traditional key fob or even a key. The most effective ones also come with battery indicators that alert you in advance when the battery is about to expire. Security Smart keys are more convenient than traditional key fobs and come with additional security and safety features. They make use of radio-frequency identification, or RFID, to communicate with the computer system in your car. If the key is within the range of the antenna it can be used to unlock the doors and start the car without needing to make use of your phone or push a button. While this may seem like a useful feature however, car thieves can hack into the system to open your doors and then start the engine. smart car key case employ a method known as “rolling codes” that prevent this from occurring. This code is projected from the key to the starter and then verified by the car's computer prior to the car starts. This prevents thieves from creating multiple copies of the key. You can also keep your car secure by not putting the phone and keys in the same pocket. Placing the two devices too close to each other could block signals, preventing them from transmitting correctly. The KeySmart Pro is a great alternative to this as it comes with a built-in Tile that helps you find your phone. If you have the app installed on your iPhone and you put the Smart Key near it, a press of its activation button causes the Tile to play an elongated melody and flash an LED. This is a lifesaver should you lose your phone or it's in silent mode. Convenience In addition to locking and unlocking your car smart keys can also be used to store and recall individual settings, such as mirror, seat and wheel positioning. Some, such as BMW's Comfort Access, even allow you to start your car without having press the ignition button. Modern smart keys communicate with car's antennas using radio waves. They transmit a unique encrypted message that is interpreted and then acted upon by the computer. These signals can be programmed for various purposes, including opening and closing the trunk or engaging locks for children. This technology is not foolproof. It is possible for thieves with a technological edge to be able to identify the frequency of an intelligent key and get its unique identification number. Fortunately, companies have been trying to enhance the security of the system. A great feature is that you can remotely lock and unlock your vehicle by tapping the screen of your smartphone. This can help you save time when loading children or cargo. It can be especially beneficial if you're an adult with teenagers who are still learning to drive. One of the best features of a smart key is its sleek and compact design. It is much more convenient to carry than other key organizers that are heavy and take up more space than needed. The KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle that could cause you to become agitated. Battery Life Typically smart keys last only half as long as regular keys with blades (two to three years, versus four to six). Smart keys must communicate with the car at a much higher frequency and more frequently to unlock and start the vehicle. Smart keys also consume more energy when placed close to electronic devices that generate electromagnetic fields like screens, computers and phones. Fortunately, the majority of smart keys come with battery backup functions. According to Open Road Auto Group most smart keys come with blades that can be used as a traditional door key in the event that the battery of the smart key dies. Many also have a separate slot that lets you insert an old-fashioned key to start the engine if the smart key is not working. Another smart key backup feature is called an “power saving mode.” If you forget to take your smart key while driving, you can drive your car as long as the engine isn't running. In order to do this, you have to lay the smart key flat against the steering column of your vehicle, while pressing the ignition button once. If you have done this correctly, your system will inform the driver that the key is depleted but it is still functional. Cost While many car owners are switching to smart keys for convenience and added security It's important to remember that these features aren't always cheap. If you lose a smart-key, it can cost a significant amount to replace it and reprogramme your car. Smart keys are similar to regular key fobs but include a microchip that can unlock or lock an automobile without the need for 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 in use for some time however it's not completely. This method has been used by thieves to steal vehicles in several cases. There are ways to stop this from happening. One method to avoid this is to use a smart key that has rolling security codes. The code changes each time the key is sent. A key fob with a display screen is also very expensive. BMW's Display Key is an example of this kind of smart key. Its LCD color touchscreen performs the usual functions of a key fob, such as locking, unlocking, and keyless start but it can also send commands from smartphones to the systems of the vehicle. This makes it easier to operate the vehicle and keep track of charging and location. It can even command the car to park itself. This is an excellent option for those with limitations in mobility or have disabilities.
