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 the need to use the traditional keyhole. Certain vehicles have them as standard features, while others offer them as an upgrade option. The technology is also more sophisticated than a traditional key fob. Some systems have emergency starting capabilities that allow you open the car and start the engine without having a key fob (or even an old-fashioned one). The most reliable systems also have indicator lights for batteries that notify you when the battery is low. Security Smart keys are a lot more efficient than traditional key fobs, and they come with additional security and safety features. They communicate with the computer system of your car using radio-frequency identification (RFID). When the key is within the range of the antenna, it can be used to unlock the doors and start the car, without the need to make use of your phone or push a button. This might seem like a convenient feature. However, smart car key repair are able to get into the system and open your doors, or even start the engine. Some manufacturers employ a process known as “rolling codes” to prevent this from happening. The code is projected by the key onto the starter, and later verified by the computer in the car prior to it starting. This is to prevent thieves from creating multiple copies of keys. You can also ensure your vehicle is safe by not putting the key and phone in the same pocket. The signals can 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 when you press the activation key, it will trigger the Tile to play a short tune and flash an LED. This can be extremely helpful in the event that you lose your phone in a dark room or even if it's on silent mode. Convenience Smart keys are able to store and retrieve personal settings, such as seat, mirror and steering wheel positions. Some, such as BMW's Comfort Access, even allow you to start your car without having to hit the ignition button. Modern smart keys utilize radio waves to communicate with antennas in the car, generating a unique encrypted signal that is read by the car's computer. These signals can be reprogrammed to perform different functions, such as opening and closing the trunk, or engaging a child lock. This technology isn't foolproof. It is possible for hackers with sophisticated technology to pick up the frequency of a smart key and intercept its unique identification number. Fortunately, the manufacturers have been trying to enhance the security of the system. A useful feature is that you can remotely lock and unlock your car by pressing the screen of your phone. This feature can save you time when loading children or cargo. It is especially useful if you have teenage kids who are learning to drive. The sleek, compact design of a smartkey is one of its greatest features. This makes it easier to carry than other key organizers that are heavy and take up a lot more space than is needed. The KeySmart is quiet and comfortable to use, eliminating that annoying jingle. Battery Life Smart keys typically last only half as long (two to three versus four to six years) as traditional fobs. The smart keys must communicate with the car at a higher frequency and more frequently to unlock and start the car. Smart keys also drain more energy when put close to electronic devices that generate electromagnetic fields such as screens, computers and phones. Most smart keys come with battery backup options. According to Open Road Auto Group most smart keys have blades that can be used as a traditional door key in the event the battery of the smart key fob fails. A majority have a slot where traditional keys can be placed to start the engine in the event that the smart key fob isn't functioning or is dead. A “power saving mode” is a second smart key backup. If you lose your smart key while driving, your car will continue to run as long as it is not running. In order to do this, you should place the smart key flat against the steering column of your vehicle while pressing the ignition button once. If you have done this correctly, the system will inform the driver that it's low on the key but still functional. Cost While many car owners are converting to smart keys for convenience and increased security, it's important to know that the cost of these features isn't always low. It can be costly to replace the lost smart key or reprogram your car. Smart keys are like traditional key fobs, but they have an embedded microchip that allows you to unlock or lock the vehicle without the need for a physical key. The chip transmits a unique code the car's system that recognizes it and validates it prior to starting the engine. This technology has existed for a while, however it isn't the perfect solution. There have been numerous instances of thieves taking vehicles using this method. The good news is that there are methods to stop this from occurring. One method to avoid this is by using the smart key which has rolling security codes. The code changes every time the key is used. A key fob with a display screen is also extremely expensive. BMW's Display Key, a smart key of this kind, is a prime example. Its LCD color screen serves all the functions that are found on a standard key fob, such as locking or unlocking the key, as well as keyless start. However, it is also able to communicate with the vehicle through smartphones. This allows you to use the vehicle and keep in mind its charging and the location of its battery. It is also able to command the vehicle to park itself. This is a great feature for people with limited mobility or disabilities.
