What You Should Know About Smart Keys Smart keys – sometimes called digital keys or information keys – let drivers access their vehicles without having to look for a keyhole. Certain vehicles have them as standard features, whereas others offer them as an upgrade option. The technology is also more advanced than a standard key fob. Certain systems allow you to start the car without the traditional key fob or even an actual key. The best systems also have indicator lights for batteries that notify you when the battery is low. Security Smart keys are more efficient than traditional fobs, and come with additional security and safety features. They connect to the computer system of your car by using radio-frequency identification (RFID). An antenna in your car will detect the signal of the key when it's in the range of the key, allowing you to unlock your doors and start the engine without needing to pull out your phone or press a button. Although this might sound like a convenient feature however, car thieves can hack into the system to open your doors and then start the engine. Some manufacturers use a technology called “rolling codes” which prevent this from occurring. smart car key replacement is projected by the key onto the starter, and then checked by the computer of the car prior to it starting. This prevents thieves from creating multiple copies of the key. You can also ensure your vehicle is secure by not putting your phone and the key in the same pocket. Signals can be blocked when the two devices are close. The KeySmart Pro is a great option because it comes with a built-in Tile which helps you locate your phone. If you have the app installed on your iPhone and place the Smart Key near it, a press of its activation button causes the Tile to emit an elongated melody and flash an LED. This could be life-saving should you lose your phone or if it's 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 alignment. Some, like BMW's Comfort Access, even allow you to start your car without having touch the ignition button. Modern smart keys use radio waves to communicate with antennas in the car. They transmit an encrypted signal that is processed by the car's computer. The signals can be reprogrammed to perform different functions such as opening and closing the trunk or engaging the child lock. This technology isn't 100% secure It is, however, not foolproof. Hackers with technical expertise can get the unique identification number of the smartkey by detecting the frequency of its transmission. Fortunately, manufacturers are striving 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 can help you save time when loading up your kids or cargo. This can be especially beneficial if you're a parent of teens who are still learning to drive. The sleek compact design of a smartkey is among its best features. It is easier to carry compared to other key organizers that can be heavy and take up more room than necessary. The KeySmart is quiet and easy to use, and eliminates the annoying jingle. Battery Life Smart keys usually last only half as long (two to three years) versus four to six years) as traditional fobs. Smart keys need to communicate with the car at a much higher rate and more frequently in order to unlock and start the vehicle. Smart keys also drain faster if they are placed close to electronic devices such as computers, phones and screens that generate electromagnetic fields. The majority of smart keys come with batteries backup options. According to Open Road Auto Group most smart keys have blades that can be used as a traditional door lock in the event the battery of the smart key fob fails. They also have a slot that lets you insert the traditional key to turn on the engine in the event that the smart key is not functioning. Another feature that smart keys offer is referred to as a “power saving mode.” If you forget to take your smart key while driving, you can still drive your vehicle for as long as the engine is not running. To achieve this, you need to place the smart key flatly against the steering column of your vehicle while pressing the ignition button one time. If you've done it correctly, the system should notify the driver that it is low on the key, but still functional. Cost While many vehicle owners are switching to smart keys for greater convenience and increased security However, it's important to realize that these features aren't cheap. If you lose a smart-key, it can cost a significant amount to replace it and then reprogramme your vehicle. Smart keys look similar to normal key fobs, however they are equipped with a microchip that can be used to unlock, lock or start a car that does not have a physical one. The chip sends a unique identifier to the vehicle's system, which recognizes it and confirms it prior beginning the engine. This technology has existed for a while, but is not yet perfect. There have been many instances of thieves taking vehicles using this method. The good news is that there are ways to prevent this from occurring. One method is to use a smart key that has security codes that roll, which changes the code every time it is transmitted. A key fob with a display screen can also be quite expensive. BMW's Display Key, a smart key with this kind of display, is a good example. Its LCD color screen serves all the functions of a traditional key fob, like locking or unlocking the key, as well as keyless start. However, it is also able to transmit commands to the vehicle from smartphones. This allows you to use the vehicle, as well as keep in mind its charging and its location. It is also able to command the vehicle to park itself, which is a great option for people with restricted mobility or disabilities.
