What You Should Know About Smart Keys Smart keys – also referred to digital keys or information keys allow drivers to access their vehicles without having to search for a keyhole. Some vehicles have them as standard features while others provide them as an upgrade. 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 a key. The most effective systems also have indicators for batteries that alert you when the battery is running low. Security Smart keys are more convenient than traditional key fobs as they have additional security and safety features. They connect to the computer system in your car through radio-frequency identification (RFID). An antenna inside your car receives the signal from your key when it is in the range, which allows you to unlock your doors and start your engine without having to pull out your phone or press the button. This might seem like an ideal feature. However, car thieves can hack into this system and open your doors, or even start the engine. Some manufacturers use a technology known as “rolling codes” that prevent this from happening. The code is projected by the key onto the starter, and is then verified by the computer in the car before it begins. This is to prevent thieves from creating multiple copies of keys. You can also keep your car secure by not placing your phone and the key in the same pocket. The signals can be blocked if the two devices are too close. The KeySmart Pro has a built in Tile that can help you locate your phone. If you have the app installed on your iPhone and you place the Smart Key near it, pressing its activation button causes the Tile to play short melodies and flash an LED. This could be life-saving should you lose your phone, or it's on silent mode. Convenience Smart keys can save and remember personal settings such as seat, mirror and steering wheel settings. Certain smart keys, such as BMW's Comfort Access system, allow you to start the car without having to touch the ignition button. Modern smart keys communicate with the car's antennas through radio waves. They send a unique encrypted message which is interpreted and then acted upon by the computer. These signals can be programmed for different functions, including opening and closing the trunk or activating the child's lock. This technology is not foolproof. Tech-savvy thieves can intercept the unique identification number of the smartkey, by spotting its frequency transmission. Fortunately, companies are trying to make the system more secure. Another benefit is the ability to remotely lock and unlock your vehicle with a tap of the phone's screen. This feature will help you save time when loading cargo or children. It's especially helpful if you have teenage kids who are learning to drive. The sleek compact design of the smartkey is among its greatest features. This makes it easier to carry than other key organizers that are heavy and take up a lot more space than necessary. The KeySmart is quiet and comfortable to use, and eliminates that annoying jingle. Battery Life Typically smart keys last about just half the time as regular keys with blades (two to three years, versus four to six). This is because the smart keys must communicate with the car more frequently and at a higher frequency to unlock it and start it. Smart keys can also be drained faster when they are placed near electronic devices such as computers, phones and screens that produce electromagnetic fields. Fortunately, most smart keys come with batteries backup features. According to Open Road Auto Group, most come with an emergency blade that works as a traditional key to unlock the door of the driver in the event that the smart key fob batteries die. Many also have a separate slot that allows you to insert an old-fashioned key to turn on the engine if the smart key is is not working. A “power saving mode” is another smart key backup. If you misplace your smart key while driving, your vehicle will continue to run even if it's not in operation. To accomplish this, you need to place the smart key flat against the steering column of your vehicle and then pressing the ignition button once. If you've done this correctly, the system will inform the driver that it's not in the right place but still functioning. Cost Smart keys are not always inexpensive. Many car owners upgrade their keys to smart ones to enhance security and convenience. It can be costly to replace a lost smart key and reprogram your car. Smart keys look similar to regular keys, but they contain a microchip which allows you to unlock, lock or start a car that does not have a physical key. The chip transmits a unique number of digits to the vehicle's computer system, which recognizes it and verifies it before beginning the engine. This technology has been around for a while, but isn't completely the perfect solution. This method has been used by thieves to steal vehicles in several cases. The good news is that there are solutions to prevent this from happening. One way to prevent this is to use an electronic key that contains rolling security codes. The code is changed each time the key is used. A key fob with display screens is extremely expensive. BMW's Display Key is an example of this kind of smart key. Its color LCD touchscreen can perform the usual functions of a key fob such as locking, unlocking and keyless start but it also transmit commands from an iPhone to the system of the vehicle. This makes it easier to operate the vehicle, and keep the track of its charging and the location of its battery. It can even command the vehicle to park itself. This is a great feature for people with limited mobility or disabilities.
