What You Should Know About Smart Keys Smart keys, also known as digital keys or information keys, allow drivers to access their vehicle without the need to use traditional keyholes. Some vehicles come with them as standard features while others have them available for upgrade. The technology is more advanced than the traditional key fob, too. Certain systems come with emergency starting capabilities that allow you to open the car and start the engine without having a key fob (or even an ordinary one). The best ones also have battery indicators that alert you in advance when the battery is about to expire. Security Smart keys are more efficient than traditional fobs, and also 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 car smart key is within range of the antenna it can be used to unlock the doors and start the car without having to use your phone or push the button. While this may sound like a useful feature however, car thieves can hack into the system to unlock your doors and then start the engine. Some manufacturers employ a process known as “rolling codes” which prevent this from happening. The code is projected by the key onto the starter, and then verified by the computer of the car prior to its start. This helps prevent thieves from making multiple copies of the keys. You can also keep your car secure by not placing the phone and key in the same pocket. If you place the two devices too close can block the signals, thus preventing the devices from communicating properly. The KeySmart Pro is a great option for this because it comes with a built-in Tile that helps to locate your phone. If you have the app installed on your iPhone and you place the Smart Key near it, the press of its activation button triggers the Tile to emit an unintentional melody and flash an LED. This can be life-saving in the event that you lose your phone in a dark space or even when it is on silent mode. Convenience In addition to locking and unlocking your car Smart keys can also store and recall individual settings, such as mirror, seat and wheel positions. Some, like BMW's Comfort Access, even allow you to start your car without having push the ignition button. Modern smart keys communicate with car's antennas by using radio waves. They transmit an encrypted message that is then interpreted and acted upon by the computer. These signals can be reprogrammed to perform different tasks, such as opening and closing the trunk, or activating children's locks. The technology isn't 100% secure. Cybercriminals with the right skills can steal the unique identification number of a smartkey by picking up the frequency of its transmission. Fortunately, companies are trying to improve the security of the system. An important feature is the ability to remotely lock and unlock your car by tapping the screen of your phone. This lets you save time when loading up your kids or cargo. This can be especially beneficial if you're a parent with teenage kids who are just beginning to learn how to drive. The sleek slim design of the smartkey is among its most appealing features. This makes it much easier to carry than other key organizers that can be bulky and take up more space than is needed. The KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle that can cause you to be irritable. Battery Life Smart keys are typically just half as long (two to three years versus four to six years) as traditional fobs. Smart keys must communicate with the car at a much higher frequency and more frequently to unlock and start the vehicle. Smart keys also drain more energy when placed near electronic devices that generate electromagnetic fields, such as screens, computers and phones. Most smart keys come with battery backup options. According to Open Road Auto Group, the majority of smart keys have an emergency blade which functions as a traditional key to unlock the door of the driver in the event that the smart key fob battery fails. Most also have a special slot that lets you insert an old-fashioned key to turn on the engine if the smart key is not working. Another feature that smart keys offer is called the “power saving mode.” If you don't remember to carry your smart key with you while driving, you can drive your vehicle for as long as the engine is not running. To do this, you have to lay the smart key flat against the steering column of your vehicle and then pressing the ignition button once. If you've done this correctly, the system will notify the driver that the key is not working but still operational. Cost Although many car owners are converting to smart keys for greater convenience and increased security However, it's important to realize that these features aren't always cheap. If you lose a smart-key, it can cost a significant amount to replace it and then reprogramme your vehicle. Smart keys are like regular keys, but have a microchip that can unlock, lock, or start vehicles without the use of a physical key. The chip transmits an unique code to the vehicle system, which detects and validates the code prior beginning the engine. This technology has been in use for some time but it's not yet perfect. There have been many instances of thieves stealing vehicles using this method. There are ways to prevent this from occurring. One way is to use smart keys that have rolling security codes that changes the code every time it's sent. A key fob that features display screens is very expensive. BMW's Display Key, a smart key of this type, is a good example. Its LCD color screen can perform all the functions of a typical key fob, including locking or unlocking the key, as well as keyless start. It can also communicate with the vehicle using a smartphone. This makes it easier to operate the vehicle and keep track of charging and location. It is also able to command the vehicle to park itself. This is a great feature for people with physical limitations or disabilities.
