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 come with them as standard features, whereas others offer them as an upgrade option. The technology is also more sophisticated than a traditional key fob. Certain systems come with emergency starting capabilities that allow you open the car and start the engine without the use of a key fob (or even an ordinary one). The most effective ones also come with battery indicators that warn you in advance when the battery is about to expire. Security Smart keys are more efficient than traditional key fobs, and they come with additional security and safety features. They communicate with the computer system in your car through radio-frequency identification (RFID). An antenna in your car receives the signal from your key when it's in the range of the key, allowing you to unlock your doors and start your engine without having to take out your phone or press a button. While this may seem like a useful feature but car thieves are also able to hack into the system to open your doors and then start the engine. Certain manufacturers employ “rolling code” technology to block this. This code is projected by the key onto the starter, and then verified by the computer of 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 putting the phone and key in the same pocket. The signals can be blocked if the two devices are close. The KeySmart Pro is a great option because it has a built-in Tile that lets to locate your phone. If you have the application installed on your iPhone and place the Smart Key near it, a press of its activation button causes the Tile to emit a short melody and flash an LED. This could be lifesaving should you lose your phone or if it's on silent mode. Convenience Smart keys can be used to store and retrieve personal settings, including seat, mirror, and steering wheel positions. Some, like BMW's Comfort Access, even allow you to start your car without having to push the ignition button. Modern smart keys communicate with car's antennas via radio waves. They transmit a unique encrypted message that is interpreted and processed by the computer. The signals can be reprogrammed to perform a variety of functions such as opening and closing the trunk, or activating children's locks. This technology is not foolproof However, it's not completely foolproof. Hackers with technical expertise can get the unique identification number of a smartkey by picking up its frequency transmission. Fortunately, companies are striving to improve the security of the system. Another feature that is useful is the ability to remotely lock and unlock your vehicle with a tap of the phone's screen. This feature will save you 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 best features. This makes it easier to carry compared to other key organizers, which can be large and take up more room than is necessary. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and comfortable to carry, and eliminates the annoying jingle which can drive you crazy. Battery Life Smart keys typically last about half the time (two to three versus four to six years) as traditional fobs. Smart keys need to communicate with the car at a higher frequency and at a higher frequency in order to unlock and start the car. Smart keys also drain faster when they are located near electronic devices like phones, computers, and screens that emit electromagnetic fields. Most smart keys come with battery backup options. According to smart car key fob replacement come with blades that can be used as a traditional door key in the event that the battery of the smart key fob fails. The majority of them have a slot in which traditional keys can be inserted 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 forget your smart key while driving, your car will continue to function even if it's not in operation. To accomplish this, you have to lay the smart key flatly against the steering column of your vehicle while pressing the ignition button once. If you have done this correctly, your system will inform the driver that the key is in use but still operational. Cost Smart keys are not always cheap. Many vehicle owners upgrade to smart keys to enhance security and convenience. It can be expensive to replace the lost smart keys and reprogram your vehicle. Smart keys are like regular keys, but have an embedded microchip that is able to unlock, lock, or start the vehicle without physically inserted keys. The chip transmits a unique code to the vehicle's system, which recognizes and validates the code prior to starting the engine. This technology has been around for some time, but is not perfect. There have been several cases of thieves taking vehicles using this method. There are methods to stop this from occurring. One option is to utilize an intelligent key with rolling security codes, which changes the code every time it is transmitted. A key fob that has a display screen can be very expensive. BMW's Display Key is an example of this kind of smart key. Its color LCD screen performs all the functions of a standard key fob, like locking the door, unlocking it, and keyless start. It can also communicate with the vehicle via an iPhone. 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 this is a fantastic option for people with restricted mobility or disabilities.
