What You Should Know About Smart Keys Smart keys, also known as digital keys or information key permit drivers to open their vehicle without the need to use the traditional keyhole. Certain vehicles have them as standard features, and others offer them as an upgrade option. The technology is also more advanced than a traditional key fob. Some systems have emergency starting features that allow you to open the car and start the engine without a key fob (or even the traditional one). The best models also have indicators for the battery 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 of your car by using radio-frequency identification (RFID). An antenna in your car receives the signal from your key when it's within the range of the key, allowing you to unlock your doors and start your engine without having to pull out your phone or press the button. This could be an ideal feature. However, criminals are able to hack into this system and unlock your doors and even start the engine. smart car key replacement use “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 starting. This stops thieves from making multiple copies of the key. You can also keep your car secure by not putting your phone and the key in the same pocket. Placing the two devices too close to each other could block signals, preventing them from communicating properly. The KeySmart Pro is a great alternative to this as it comes with a built-in Tile that helps you find your phone. If you have the app installed on your iPhone and you put the Smart Key near it, the press of its activation button triggers the Tile to play a short melody and flash an LED. This is a lifesaver when you've lost your phone in a dark place or even if it's in silent mode. Convenience In addition to locking and unlocking your car, a smart key can also be used to store and recall individualized settings like mirror, seat and wheel positions. Some, such as BMW's Comfort Access, even allow you to start your car without having to hit the ignition button. Modern smart keys make use of radio waves to communicate with antennas inside the car, transmitting an encrypted, unique signal that is then interpreted by the car's computer. These signals can be modified to perform various functions such as opening and closing the trunk, or activating an electronic child lock. The technology isn't completely foolproof However, it is not foolproof. Criminals with a sophisticated technology can steal the unique identification number of the smartkey, by spotting its frequency transmission. Fortunately for us, the industry has been striving to increase the security of the system. A great feature is the ability to remotely lock and unlock your car by pressing the screen of your phone. This allows you to save time when loading up children or cargo. It can be especially useful if you're an adult with teenagers who are still learning to drive. The sleek slim design of a smartkey is one of its most appealing features. This makes it much easier to carry than other key organizers, which can be heavy and take up more room than needed. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and comfortable to carry, eliminating that annoying jingle that can cause you to become agitated. Battery Life Smart keys generally last only half as long (two to three years versus four to six years) as regular fobs. This is due to the fact that the smart keys need to communicate with the car more frequently and at a higher speed to unlock and start it. Smart keys also drain faster if they are placed close to electronic devices such as computers, phones and screens that generate electromagnetic fields. Fortunately, the majority of smart keys come with battery backup features. According to Open Road Auto Group, the majority of smart keys have an emergency blade which functions as traditional keys to open the driver's door in case the smart key fob's batteries fail. Most have a slot that traditional keys can be put in to start the engine in the event that the smart key fob isn't working or is dead. A “power saving mode” is another smart key backup. If you misplace your smart key while driving, your vehicle will still run until it is not in operation. To do this simply lay the smart key flat on the steering column while pressing the ignition button. If you have done this correctly, the system will inform the driver that the key is not working but is functional. Cost While many car owners are upgrading to smart keys for convenience and security, it's important to know that these features aren't always cheap. If you lose a smart key it can cost a fortune to replace it and also reprogramme the car. Smart keys look like regular keys, however they have a microchip that can be used to unlock, lock or start a car without having a physical one. The chip transmits a unique code to the vehicle system, which identifies and verifies the code before starting the engine. This technology has existed for some time, but isn't completely yet perfect. This method has been employed by thieves to steal cars in several cases. There are ways to stop this from occurring. One option is to utilize an intelligent key with security codes that roll, which changes the code each time it is transmitted. A key fob with display screens can be extremely costly. BMW's Display Key, a smart key with this kind of display, is an example. Its color LCD touchscreen can perform the basic functions of a keyfob such as locking, unlocking and keyless start, but it can also transmit commands from a smartphone to the vehicle's systems. This makes it much easier to operate the vehicle and keep the track of charging locations and battery levels. It is also able to command the car to park itself. This is an excellent feature for people with limited mobility or disabilities.
