What You Should Know About Smart Keys Smart keys, also known as digital keys or information keys can allow drivers to gain access to their vehicle without the need to use the traditional keyhole. Some vehicles come with them as standard features while others offer them for upgrade. The technology is also more advanced than a standard key fob. Some systems allow you to start your car without the traditional key fob or even a key. The best 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 fobs and also come with additional security and safety features. They communicate with the computer system of your car by using radio-frequency identification (RFID). An antenna inside your car detects the signal from the key when it is within distance, allowing you unlock your doors and start the engine without having to take out your phone or press a button. While this may sound like a useful feature however, car thieves can hack into the system to unlock your doors and start the engine. Certain manufacturers employ a technique called “rolling codes” that prevent this from occurring. The code is projected by the key onto the starter, and then verified by the computer of the car prior to it starting. This prevents thieves creating multiple copies of the keys. Another way to ensure that your vehicle secure is to ensure that you do not place the key and mobile phone in the same pocket. If you place the two devices too close together could block signals, stopping them from communicating correctly. The KeySmart Pro is a great option to do this since it has a built-in Tile which helps you locate your phone. When you place the Smart Key next to your iPhone with the app installed and press the activation button, it will trigger the Tile to play a short tune and flash an LED. This could be life-saving in the event that you lose your phone or it's in silent mode. Convenience Smart keys are able to store and retrieve personal settings, like seat, mirror and steering wheel position. Some, like 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 by using radio waves. They send a unique encrypted message that is then interpreted and then acted upon by the computer. These signals can be reprogrammed for different functions, including opening and closing the trunk or activating the lock of a child. The technology isn't 100% secure. Criminals with a sophisticated technology can steal the unique identification number of a smartkey through its frequency transmission. Fortunately, manufacturers are trying to make the system more secure. Another useful feature is the ability to remotely lock or unlock your vehicle using a simple tap of the phone's screen. This can help you save time when loading up children or cargo and can be especially beneficial if you're parents of teenagers who are just learning to drive. One of the most appealing features of a smart key is its sleek, compact design. This makes it easier to carry than other key organizers, which can be heavy and take up more room than needed. The KeySmart is quiet and easy to use, eliminating that annoying jingle. 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 must communicate with the car more frequently and at a higher rate to unlock and begin the. Smart keys also drain more energy when put close to electronic devices that generate electromagnetic fields like computers, phones and screens. Fortunately, most 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 door lock in the event the battery of the smart key fails. A majority have a slot where traditional keys can be inserted to start the engine in the event that the smart key fob is not working or is dead. A “power saving mode” is a different smart key backup. If you forget your smart key while driving, your car will continue to function regardless of whether it's not in operation. To do this, lay the smart key flat on the steering column and press the ignition button. If you've done it correctly, the system will inform the driver that the key is in use but it is still functional. Cost Smart keys are not always affordable. Many owners of vehicles upgrade to smart keys to enhance security and convenience. smart key for car can be expensive to replace the lost smart key or reprogram your car. Smart keys look similar to regular keys, but they have a microchip that can unlock, lock or start a car that does not have a physical key. The chip transmits an unique code to the vehicle's system, which recognizes and verifies the code before starting the engine. This technology has been around for a while but it's not yet perfect. There have been a few instances of thieves stealing vehicles using this method. The good news is that there are solutions to prevent this from happening. One option is to use a smart key that has rolling security codes that alters the code each time it's used. A key fob with display screens is very expensive. BMW's Display Key is an example of this type of smart key. Its LCD color screen performs all the functions of a typical key fob, like locking the door, unlocking it, and keyless start. It can also send commands to the vehicle through smartphones. This makes it much easier to operate the vehicle and keep an eye on charging and location. It can even command the vehicle to park itself which is an excellent feature for those with limited mobility or disabilities.
