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 having to fiddle with a traditional keyhole. Certain vehicles include them as standard features, whereas others offer them as an upgrade option. The technology is much more advanced than the traditional key fob as well. Some systems let you start the car without the traditional key fob or even the use of a key. The best ones also have battery indicators that alert you in advance when the battery is about to run out. Security Smart keys are more efficient than traditional key fobs and come with added security and safety features. They utilize radio-frequency identification or RFID, to connect with your car's computer system. An antenna in your car reads the signal from the key when it is within range, allowing you to unlock your doors and start your engine without having to pull out your phone or press a button. Although this might sound like a useful feature however, car thieves can hack into the system to open your doors and start the engine. Some manufacturers use “rolling code” technology to block this. 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 keep your car safe is to make sure that you do not put your mobile phone and key in the same pocket. Placing the two devices too close to each other can block the signals, which can stop the devices from communicating properly. The KeySmart Pro is a great alternative to this as it comes with a built-in Tile that lets you find your phone. If you have the application installed on your iPhone and you put the Smart Key near it, pressing its activation button triggers the Tile to emit an elongated melody and flash an LED. This can be extremely helpful in case you've lost your phone in a dark room or even when it is in silent mode. Convenience In addition to locking and unlocking your vehicle, a smart key can also be used to store and recall individualized settings like mirror, seat and wheel positioning. Certain smart keys, like BMW's Comfort Access system, allow you to start the car without having to touch the ignition button. Modern smart keys use radio waves to communicate with antennas within the car. They transmit an encrypted, unique signal that is read by the car's computer. The signals can be reprogrammed for different functions, including opening and closing the trunk or activating the lock of a child. This technology isn't 100% secure, however. Tech-savvy thieves can intercept the unique identification number of the smartkey by detecting the frequency of its transmission. Fortunately, manufacturers have been striving to increase the security of the system. One of the most useful features is that you can remotely lock and unlock your car by tapping the screen of your smartphone. This allows you to save time when loading children or cargo, and is particularly beneficial if you're an adult with teenagers who are just learning to drive. One of the best aspects of a smart key is its sleek slim design. This makes it much simpler to carry than other key organizers, which can be clunky and take up more space than needed. The KeySmart is quiet and easy to use, eliminating that annoying jingle. Battery Life Typically, smart keys last only half as long as regular keys with key blades (two to three years, versus four to six). Smart keys need to communicate with the car at a higher frequency and more frequently to unlock and start the car. Smart keys can also be drained faster when they are placed near electronic devices like computers, phones and screens that emit electromagnetic fields. Most smart keys come with batteries backup options. According to Open Road Auto Group, the majority of them have an emergency blade that acts as a traditional key to open the door for the driver in case the smart key battery dies. The majority of them have a slot in which a traditional key can be put in to start the engine in the event that the smart key fob isn't working or is dead. A “power saving mode” is a second smart key backup. If you forget your smart key while driving, your car will continue to function until it is not in operation. To accomplish this, you need to place the smart key flat against the steering column of your vehicle, while pressing the ignition button one time. If you've done this correctly, your system will inform the driver that the key is in use but it's still functioning. Cost Smart keys are not always affordable. Many vehicle owners upgrade their keys to smart ones to improve convenience and security. If you lose a smart-key, it can cost a significant amount to replace it and also reprogramme the car. Smart keys appear like regular keys, however they contain a microchip, which can be used to unlock, lock or start a vehicle without a physical one. The chip transmits a unique code to the vehicle system, which recognizes and verifies the code before starting the engine. This technology has been in use for a while but it's not completely. There have been smart car key fob replacement of thieves stealing cars using this method. There are ways to prevent this from occurring. One way to avoid this is by using a smart key that has rolling security codes. The code is changed each time the key is used. A key fob with an LCD screen can be very expensive. BMW's Display Key, a smart key of this type, is a prime example. Its color LCD screen performs all the functions of a standard key fob, like locking the door, unlocking it, and keyless start. It can also send commands to the vehicle from smartphones. This allows you to use the vehicle, and keep track of its charging and whereabouts. It can even instruct the car to park itself. This is an excellent feature for those with physical limitations or disabilities.
