What You Should Know About Smart Keys Smart keys – also known as digital keys or information keys – permit drivers to use their vehicles without fumbling around with the keyhole. Some vehicles have them as standard features, while others offer them for upgrade. The technology is also more advanced than a traditional key fob. Some systems let you start your vehicle without a traditional key fob or even an actual key. The most effective systems also have indicators for the battery that warn you when the battery is running low. Security Smart keys are more practical than traditional keys and also come with additional security and safety features. They connect to the computer system in 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 having to use a phone or push the button. This may seem like an easy feature. However, criminals are able to get into the system and unlock your doors and even start the engine. Certain manufacturers employ “rolling code” technology to prevent this. The code is projected from the key to the starter, and then verified by the car's computer prior the car starts. This prevents thieves from creating multiple copies of the key. You can also keep your car safe by not putting your phone and the key in the same pocket. Putting the two devices too close together could block signals, which can stop the devices from communicating properly. 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 app installed and press the activation button, it will trigger the Tile to play a brief tune and flash an LED. This can be a lifesaver in the event that you lose your phone in a dark place or even when it is in silent mode. Convenience In addition to locking and unlocking your vehicle smart keys can also save and recall personal settings such as seat, mirror and steering wheel alignment. Some, like BMW's Comfort Access, even allow you to start your vehicle without having to push the ignition button. Modern smart keys use radio waves to communicate with antennas inside the car, generating an encrypted, unique signal that is processed by the car's computer. These signals can be modified to perform different functions for example, opening and closing the trunk or engaging the child lock. This technology isn't foolproof. It is possible for hackers with sophisticated technology to pick up the frequency transmission of an intelligent key and get its unique identification number. Fortunately for us, the industry has been striving to increase the security of the system. Another benefit is the ability to remotely lock and unlock your vehicle with a tap of the phone's screen. This feature can save you time when loading cargo or children. It's particularly useful for parents of teenagers who are learning to drive. The sleek and compact design of the smartkey is among its best features. This makes it much easier to carry compared to other key organizers that are bulky and take up more space than is necessary. The KeySmart is quiet and easy to use, removing the annoying jingle. Battery Life Smart keys usually last only half as long (two to three versus four to six years) as regular fobs. Smart keys must communicate with the car at a much higher frequency and more frequently in order to unlock and start the vehicle. Smart keys will also drain faster when they are located close to electronic devices such as phones, computers or screens that generate electromagnetic fields. Most smart keys come with battery backup options. According to Open Road Auto Group, most have an emergency blade that functions as an ordinary key to unlock the door of the driver in case the smart key fob battery fails. Most have a slot where an old-fashioned key can be used to start the engine in the event that the smart key fob is not working or dead. Another smart key backup feature is called the “power saving mode.” If you do not take your smart key while driving, you are able to drive your car for as long as the engine isn't running. To accomplish this, you must place the smart key flatly against the steering column of your vehicle while pressing the ignition button one time. If you have done this correctly, the system will notify the driver that it is low on the key, but still functional. Cost Smart keys are not always affordable. Many car owners upgrade to smart keys to increase convenience and security. If you have lost a smart key it can cost a fortune to replace it and also reprogramme the car. Smart keys are like regular keys but come with a microchip that can unlock, lock, or start a vehicle without a physical key. The chip transmits a unique number of digits to the vehicle's computer system, which recognizes the code and confirms it prior to beginning the engine. This technology has been around for a while however it's not yet perfect. There have been several cases of thieves taking vehicles using this method. There are ways to prevent this from happening. One option is to utilize smart keys that have rolling security codes that alters the code every time it's sent. A key fob with a display screen can also be extremely expensive. BMW's Display Key, a smart key of this kind is a prime example. Its color LCD touchscreen can perform the standard functions of a key fob like locking, unlocking, and keyless start, but it can also transmit commands from an iPhone to the system of the vehicle. G28 Car Keys makes it easier to use the vehicle, and keep the track of its charging and location. It can even instruct the car to park itself. This is a fantastic feature for people with handicaps or mobility issues.
