What You Should Know About Smart Keys Smart keys, also referred to as digital keys or information key, allow drivers to access their vehicle without the need to use a traditional keyhole. Certain vehicles come with them as standard features, while others allow them to be upgraded. The technology is also more advanced than a traditional key fob. Some systems allow you to start your car without the traditional key fob or even the use of a key. The most effective ones also have indicators for battery which warn you ahead of time when the battery is about to expire. Security Smart keys are more useful than traditional keys as they have added security and safety features. They communicate with the computer system of your car via radio-frequency identification (RFID). If the key is within the range of the antenna it is able to unlock the doors and start the car without needing to use your phone or push the button. While this may sound like a great idea, car thieves can also hack into the system to unlock your doors and then start the engine. Certain manufacturers employ “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 starting. This stops thieves from making multiple copies of the key. You can also keep your car secure by not placing your phone and the key in the same pocket. Putting the two devices too close could block signals, thus preventing the devices from communicating properly. The KeySmart Pro has a built in Tile that will help you locate your phone. If you have the application installed on your iPhone and you place the Smart Key near it, a press of its activation button triggers the Tile to play short melodies and flash an LED. This can be life-saving in case you've lost your phone in a dark area or even when it is on silent mode. Convenience Smart keys can store and recall personal settings like mirror, seat and steering wheel position. Certain smart keys, for instance BMW's Comfort Access system, allow you to start your car without pressing the ignition button. Modern smart keys communicate with the car's antennas through radio waves. They transmit a unique encrypted message that is interpreted and then acted upon by the computer. The signals can be reprogrammed for various purposes, including opening and closing the trunk or engaging locks for children. This technology isn't foolproof. It is possible for thieves with a technological edge to pick up the frequency transmission of the smart key and steal its unique identification number. Fortunately, manufacturers are striving to improve the security of the system. Another feature that is useful is the ability to remotely lock or unlock your vehicle using a simple tap of the phone's screen. This will save time when loading children or cargo. smart car key replacement can be especially useful if you're a parent of teens who are still learning to drive. One of the best features of a smart key is its sleek, compact design. It is easier to carry than other key organizers that can be large and take up more space than necessary. The KeySmart is also quiet and comfortable to carry, and eliminates the annoying jingle that can make you shiver. Battery Life Typically smart keys last for less than regular fobs with key blades (two to three years, versus four to six). Smart keys need to communicate with the car at a higher frequency and at a higher frequency in order to unlock and start the vehicle. Smart keys can also be drained faster when they are located near electronic devices like phones, computers, and screens that generate electromagnetic fields. The majority of smart keys have batteries backup options. According to Open Road Auto Group, the majority of them come with an emergency blade which functions as traditional keys to open the door of the driver in the event that the smart key fob battery fails. Most have a slot that an old-fashioned key can be placed to start the engine in the event that the smart key fob is not working or dead. A “power saving mode” is another smart key backup. If you lose your smart key while driving, your car will continue to run for even if it's not in operation. To do this, place the smart key flat on the steering column and press the ignition button. If you have done this correctly, the system will inform the driver that it is low on the key, but nonetheless functional. Cost Smart keys are not always inexpensive. Many vehicle owners upgrade to smart keys to enhance security and convenience. It can be costly to replace a lost smart key and reprogram your car. Smart keys are like regular key fobs but include an embedded microchip that allows you to unlock, lock, or start a vehicle without a physical key. The chip sends a unique identifier to the vehicle's system, which recognizes it and verifies it before starting the engine. This technology has been around for some time, but it's not the perfect solution. There have been a few instances of thieves stealing cars using this method. There are methods to stop this from occurring. One option is to utilize smart keys that have security codes that roll, which changes the code every time it is transmitted. A key fob with a display screen can also be very expensive. BMW's Display Key is an example of this kind of smart key. Its LCD color touchscreen serves the basic functions of a key fob like locking, unlocking and keyless start but it can also send commands from a smartphone to the vehicle's systems. This makes it easier to use the vehicle, and also keep in mind its charging and the location of its battery. It is also able to command the vehicle to park itself, which is a great feature for people with limited mobility or disabilities.
