What You Should Know About Smart Keys Smart keys, also referred to as keys that are digital or information keys can allow drivers to gain access to their vehicle without the need to use a traditional keyhole. Certain vehicles have them as standard features, while others offer them as an upgrade option. The technology is more advanced than the traditional key fob, as well. Certain systems have emergency start capabilities that let you open the car and start the engine without a key fob (or even an old-fashioned one). 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 convenient than traditional key fobs and also come with additional security and safety features. They connect to the computer system of your car using radio-frequency identification (RFID). An antenna mounted on 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. This might seem like an ideal feature. However, thieves are able to penetrate this system and unlock your doors or even 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 is then verified by the computer in the car prior to its start. This stops thieves from creating multiple copies of keys. You can also ensure your vehicle is secure by not putting the phone and key in the same pocket. The signals could be blocked when the two devices are placed too close. 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, pressing the activation button will trigger the Tile to play a brief tune and flash an LED. This can be extremely helpful in case you've lost your phone in a dark space or even if it is on silent mode. Convenience In addition to locking and unlocking your vehicle, a smart key can also save and recall individual settings, such as mirror, seat and wheel alignment. Certain smart keys, like BMW's Comfort Access system, allow you to start the car without pressing the ignition button. Modern smart keys communicate with car's antennas through radio waves. They send a unique encrypted message that is read and then acted upon by the computer. These signals can be reprogrammed to perform a variety of functions, such as opening and closing the trunk or engaging an electronic child lock. This technology isn't completely foolproof. It's possible for tech-savvy thieves to pick up the frequency of a smart key and intercept its unique identification number. Fortunately, smart forfour key programming G28CarKeys are working to make the system more secure. Another useful feature is the capability to remotely lock and unlock your vehicle by tapping of the phone's screen. This feature can help you save time when loading children or cargo. It's particularly helpful if you have teenage kids who are learning to drive. One of the most appealing features of a smart key is its sleek compact design. This makes it much easier to carry than other key organizers, which can be clunky and take up more space than needed. The KeySmart is also quiet and easy to carry, removing the annoying jingle that can cause you to become agitated. Battery Life Smart keys typically last just half as long (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 rate to unlock and begin the. Smart keys can also be drained faster when they are placed near electronic devices such as computers, phones and screens that generate electromagnetic fields. Fortunately, many smart keys come with batteries backup features. According to Open Road Auto Group most smart keys have blades that can be used as a traditional key for doors in the event the battery of the smart key fob dies. The majority of them have a slot in which an old-fashioned 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 misplace your smart key while driving, your vehicle will still run until it is not running. To accomplish this, you should place the smart key flatly against the steering column of your vehicle before pressing the ignition button one time. If you do this correctly, your system should notify the driver that the key is depleted but it is still functional. Cost Smart keys are not always inexpensive. Many car owners upgrade their keys to smart ones to enhance security and convenience. It can be expensive to replace an unusable smart key and reprogram your car. Smart keys are like regular keys but come with the capability of a microchip to unlock or lock vehicles without the use of the use of a physical key. The chip transmits an unique code to the vehicle system, which detects and validates the key before beginning the engine. This technology has been in use for a while however it's not perfect. This technique has been used by thieves to rob vehicles in numerous instances. The good news is that there are solutions to stop this from occurring. One option is to use an intelligent key with rolling security codes, which changes the code every time it's used. A key fob that features a display screen is also very expensive. BMW's Display Key is an example of this kind of smart key. Its LCD color screen performs all the functions of a standard key fob like locking, unlocking, and keyless start. However, it can also communicate with the vehicle from the smartphone. This makes it much easier to operate the vehicle and keep track of charging and location. It can even instruct the vehicle to park itself which is an excellent feature for people with limited mobility or disabilities.
