What You Should Know About Smart Keys Smart keys, also referred to as keys that are digital or information keys enable drivers to get into their vehicle without having to fiddle with a traditional keyhole. Certain vehicles have them as standard features, and others offer them as an upgrade option. The technology is much more advanced than the traditional key fob, too. Certain systems let you start your car without the traditional key fob, or even the use of a key. The best systems also include battery indicators which warn you when the battery is low. 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 connect with your car's computer system. An antenna mounted on your car will detect the signal of the key when it is in distance, allowing you unlock your doors and start your engine without having to take out your phone or press the button. smart car key fob might seem like an ideal feature. However, car thieves are able to get into the system and unlock your doors and even start the engine. Certain manufacturers employ a technique called “rolling codes” that stop this from occurring. The code is projected by the key onto the starter and later verified by the computer of the car before it starts. This stops thieves from making multiple copies of the key. You can also ensure your vehicle is secure by not putting the key and phone in the same pocket. Putting the two devices too close could block signals, which can stop them from communicating properly. The KeySmart Pro has a built in Tile that helps you locate your phone. When you place the Smart Key next to your iPhone with the application installed by pressing the activation button, it will trigger the Tile to play a short tune and flash an LED. This is a lifesaver when you've lost your phone in a dark space or even when it is in silent mode. Convenience Smart keys can save and recall personal settings including seat, mirror and steering wheel settings. Some, such as BMW's Comfort Access, even allow you to start your vehicle without having to press the ignition button. Modern smart keys utilize radio waves to communicate with antennas within the car, sending an encrypted signal that is interpreted by the car's computer. The signals can be reprogrammed for different functions, including opening and closing the trunk or engaging 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 for us, the industry has been striving to increase the security of the system. A great feature is that you can remotely lock and unlock your car by pressing the screen of your smartphone. This can help you save time when loading up your kids or cargo and can be especially helpful if you are a parent of teens who are just beginning to learn how to drive. The sleek, compact design of a smartkey is among its greatest features. It is much more convenient to carry than other key organizers that can be bulky and take up more space than needed. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and comfortable to carry, and eliminates the annoying jingle that could cause you to be irritable. Battery Life Smart keys typically last about half the time (two to three years, versus four to six years) as regular fobs. This is because the smart keys need to communicate with the car more frequently and at a higher speed to unlock it and start it. Smart keys will also drain faster when placed close to electronic devices, such as phones, computers, and screens that produce electromagnetic fields. Fortunately, the majority of smart keys come with battery backup functions. According to Open Road Auto Group most smart keys come with a blade that can be used as a traditional door key in the event that the battery of the smart key fails. Most have a slot that traditional keys can be used to start the engine in the event that the smart key fob is not working or is dead. Another feature of the smart key backup is known as an “power saving mode.” If you forget to bring your smart key with you while driving, you are able to drive your vehicle as long as the engine is not running. To do this, lay the smart key flat on the steering column and press the ignition button. If you've done this correctly, the system should notify the driver that it is low on the key, but still functioning. Cost Although many car owners are switching to smart keys for convenience and security It's important to understand that these features aren't always cheap. It can be costly to replace an unusable smart key and reprogram your car. Smart keys are similar to traditional key fobs, but they have an embedded microchip that allows you to unlock, lock, or start the vehicle without the need for a physical key. The chip transmits a unique number of digits to the vehicle's computer system, which recognizes it and verifies it before beginning the engine. This technology has been in use for a long time, but isn't yet perfect. This method has been used by thieves to steal vehicles in numerous instances. There are ways to prevent this from occurring. One way is to use a smart key that has rolling security codes, which changes the code each time it is transmitted. A key fob with a display screen can be extremely expensive. BMW's Display Key, a smart key with this kind of display, is an example. Its LCD color touchscreen performs the typical functions of a key fob like locking, unlocking, and keyless start but it can also send commands from smartphones to the car's systems. This allows you to use the vehicle, and also keep the track of its charging and its location. It is also able to command the vehicle to park itself, which is a great feature for people with limited mobility or disabilities.
