What You Should Know About Smart Keys Smart keys – also referred to digital keys or information keys – permit drivers to use their vehicles without having to search for a keyhole. Some vehicles have them as standard features, whereas others have them available for upgrade. The technology is better than the traditional key fob, too. Some systems have emergency starting capabilities that allow you open the car and start the engine without a key fob (or even an ordinary one). The most reliable systems also have indicator lights for batteries that notify you when the battery is running low. Security Smart keys are a lot more convenient than traditional key fobs, and they come with additional security and safety features. smart car key not working connect to the computer system in your car through radio-frequency identification (RFID). An antenna on your car detects the signal from the key when it is within distance, allowing you unlock your doors and start the engine without taking out your phone or press the button. This might seem like an excellent feature. However, car thieves are able to get into the system and unlock your doors and even start the engine. Certain manufacturers employ a method called “rolling codes” which prevent this from occurring. The code is projected by the key onto the starter and then checked by the computer in the car before it begins. This stops thieves from creating multiple copies of the keys. Another method to keep your vehicle secure is to ensure that you don't put the mobile phone and the key in the same pocket. The signals could be blocked if the two devices are placed too close together. The KeySmart Pro is a great option because it comes with a built-in Tile which helps to locate your phone. When you place the Smart Key next to your iPhone with the application installed by pressing the activation button, it will cause the Tile to play a brief tune and flash an LED. This can be life-saving when you've lost your phone in a dark area or even if it is on silent mode. Convenience In addition to locking and unlocking your car Smart keys can also be used to store and recall individual settings such as mirror, seat and wheel positioning. Some smart keys, like BMW's Comfort Access system, allow you to start the car without pressing the ignition button. Modern smart keys utilize radio waves to communicate with antennas inside the car, transmitting a unique encrypted signal that is then interpreted by the car's computer. The signals can be reprogrammed to perform different tasks like opening and closing the trunk, or engaging an electronic child lock. This technology isn't 100% secure It is, however, not foolproof. It is possible for thieves with a technological edge to pick up the frequency of the smart key and steal its unique identification number. Fortunately, manufacturers have been working to improve the security of the system. Another feature that is useful is the possibility to remotely lock and unlock your vehicle using a simple tap of the phone's screen. This feature will save you time when loading cargo or children. It's especially helpful in the case of teens who are learning to drive. The sleek, compact design of a smartkey is among its greatest features. It is easier to carry than other key organizers, which can be bulky and take up more space than they need. The KeySmart is quiet and comfortable to use, eliminating that annoying jingle. Battery Life Smart keys generally last only half as long (two to three years) versus four to six years) as traditional fobs. The smart keys have to communicate with the vehicle at a greater rate and more frequently to unlock and start the car. Smart keys also consume more energy when placed near electronic devices that create electromagnetic fields such as phones, computers and screens. Fortunately, many 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 that the battery of the smart key fob fails. Most also have a special slot where you can insert traditional keys to start the engine in the event that the smart key is dead or not working. A “power saving mode” is another smart key backup. If you forget your smart key while driving, your car will still run even if it's not in operation. 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 have done this correctly, the system will inform the driver that the key is low but is functional. Cost Smart keys aren't always inexpensive. Many vehicle owners upgrade to smart keys to enhance security and convenience. It can be costly to replace an unusable smart key and reprogram your car. Smart keys look like regular keys, but they contain a microchip, which can be used to unlock, lock or start a car without having a physical key. The chip transmits an unique code to the vehicle's system, which detects and validates the code prior to starting the engine. This technology has existed for a long time, but is not fully developed. This technique has been employed by thieves to steal vehicles in a variety of cases. The good news is that there are ways to prevent this from occurring. One method is to use a smart key with rolling security codes, which alters the code each time it is transmitted. A key fob that has 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 traditional key fob like locking, unlocking, and keyless start. It can also send commands to the vehicle using smartphones. This makes it easier to operate the vehicle, as well as keep on top of its charging status and its location. It can even command the vehicle to park itself, which is a great feature for people with limited mobility or disabilities.
