What You Should Know About Smart Keys Smart keys, also known as keys that are digital or information keys can allow drivers to gain access to their vehicle without having to fiddle with traditional keyholes. Certain vehicles include them as standard features, and 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 the use of a key fob (or even an ordinary one). The best ones also have battery indicators which warn you ahead of time when the battery is about to run out. Security Smart keys are more efficient than traditional fobs, and come with additional security and safety features. They connect to the computer system in your car through radio-frequency identification (RFID). An antenna in your car detects the signal from the key when it's within the range, which allows 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 but car thieves are also able to hack into the system to open your doors and then start the engine. Certain manufacturers use “rolling code” technology to ward off this. This code is projected from the key to the starter and is verified by the car's computer before starting. This stops thieves from making multiple copies of the key. Another method to keep your vehicle secure is to ensure that you don't place the key and mobile phone in the same pocket. Putting the two devices too close together could block signals, thus preventing them from communicating correctly. The KeySmart Pro has a built in Tile that helps you locate your phone. If you have the app installed on your iPhone and you place the Smart Key near it, a press of its activation button causes the Tile to play an elongated melody and flash an LED. This is a lifesaver if you have lost your phone in a dark place or even if it is on silent mode. Convenience Smart keys can store and retrieve personal settings, like seat, mirror and steering wheel settings. Some, like BMW's Comfort Access, even allow you to start your vehicle without having to push the ignition button. Modern smart keys communicate with car's antennas by using radio waves. They send a unique encrypted message that is read and processed by the computer. These signals can be reprogrammed to perform various functions, such as opening and closing the trunk, or activating a child's lock. This technology isn't foolproof However, it is not foolproof. Cybercriminals with the right skills can steal the unique identification number of the smartkey, by spotting its frequency transmission. Thankfully, the manufacturers are trying to make the system more secure. A great feature is that you can remotely lock and unlock your car by pressing the screen of your phone. This lets you save time when loading children or cargo. It can be particularly beneficial if you're an adult with teenagers who are just learning to drive. The sleek and compact design of the smartkey is among its greatest features. G28CarKeys makes it much easier to carry than other key organizers, which can be large and take up more space than needed. The KeySmart is quiet and comfortable to use, and eliminates that annoying jingle. Battery Life Smart keys usually last only half as long (two to three years, versus four to six years) as regular fobs. The smart keys have to communicate with the car at a higher rate and more frequently to unlock and start the vehicle. Smart keys also consume more energy when placed near electronic devices that generate electromagnetic fields like phones, computers, and screens. Fortunately, most smart keys come with batteries backup features. According to Open Road Auto Group, they have an emergency blade which functions as an old-fashioned key to open the driver's door in the event that the smart key fob battery fails. Most have a slot that the traditional key can be used to start the engine in the event that the smart key fob isn't working or dead. Another smart key backup feature is referred to as”power saving mode. “power saving mode.” If you don't remember to carry your smart key with you while driving, you'll be able to drive your car 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 once. If you have done this correctly, the system will inform the driver that it is low on the key but still functioning. Cost Many car owners are switching to smart keys for convenience and added security However, it's important to realize that these features aren't cheap. It can be costly to replace an unusable smart key and reprogram your vehicle. Smart keys are similar to regular keys, but have an embedded microchip that allows you to unlock or lock the vehicle without physically inserted keys. The chip transmits a unique code to the vehicle's system, which identifies and verifies the code before starting the engine. This technology has been in use for some time however it's not completely. This method has been used by thieves to steal vehicles in several cases. The good news is that there are ways to prevent this from occurring. One way to avoid this is to use an electronic key that contains rolling security codes. The code changes every time the key is sent. A key fob that features display screens is extremely expensive. BMW's Display Key is an example of this type of smart key. Its LCD color touchscreen performs the usual functions of a key fob such as locking, unlocking and keyless start, but it can also send commands from an iPhone to the system of the vehicle. This allows you to use the vehicle, and keep on top of its charging status and its location. It can even command the car to park itself. This is an excellent option for those with physical limitations or disabilities.
