What You Should Know About Smart Keys Smart keys – also referred to digital keys or information keys let drivers access their vehicles without having to look 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. Certain systems have emergency start features that allow you to open the car and start the engine without the use of a key fob (or even an old-fashioned one). The most effective ones also come with battery indicators which warn you ahead of time when the battery is about to run out. Security Smart keys are more convenient than traditional fobs and include additional security and safety features. They communicate with the computer system in your car using radio-frequency identification (RFID). An antenna mounted on your car reads the signal from the key when it's within range, allowing you to unlock your doors and start your engine without having to take out your phone or press the button. This might seem like a convenient feature. However, car thieves are able to access this system to unlock your doors and even start the engine. Some manufacturers use a technology known as “rolling codes” to prevent this from occurring. This code is projected from the key to the starter and then verified by the car's computer prior to beginning. This prevents thieves from creating multiple copies of the key. You can also ensure your vehicle is safe by not putting the key and phone in the same pocket. Placing the two devices too close together can block the signals, stopping them from transmitting correctly. The KeySmart Pro has a built in Tile that helps you locate your phone. When you place the Smart Key next to your iPhone with the app installed and press the activation button, it will trigger the Tile to play a short tune and flash an LED. This can be extremely helpful in case you've lost your phone in a dark space or even when it is in silent mode. Convenience In addition to locking and unlocking your vehicle smart keys can also save and recall individual settings, such as mirror, seat and wheel alignment. Some smart keys, like 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 via radio waves. They transmit an encrypted message which is interpreted and processed by the computer. These signals can be reprogrammed to perform various functions, such as opening and closing the trunk, or engaging the lock of a child. This technology isn't foolproof. It's possible for tech-savvy thieves to detect the frequency transmission of an intelligent key and get its unique identification number. Fortunately, the manufacturers have been trying to enhance the security of the system. Another great feature is the ability to remotely lock or unlock your vehicle with a single tap of the phone's screen. This can help you save time when loading children or cargo. It can be especially useful if you're a parent with teenage kids who are just learning how to drive. One of the best features of a smart key is its sleek, compact design. This makes it much simpler to carry than other key organizers which can be bulky and take up more space than necessary. The KeySmart is quiet and comfortable to use, and eliminates that annoying jingle. Battery Life Smart keys are typically just half as long (two to three years versus four to six years) as traditional fobs. Smart keys must 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 put close to electronic devices that generate electromagnetic fields such as phones, computers and screens. The majority of smart keys come with battery backup options. According to Open Road Auto Group, the majority of smart keys come with an emergency blade which functions as a traditional key to open the door for the driver in the event that the smart keys fob battery fails. A majority have a slot where the traditional key can be used to start the engine in the event that the smart key fob is not functioning or is dead. A “power saving mode” is another smart key backup. If you forget your smart key while driving, your car will continue to run for as long as it is not in operation. To do this, lay the smart key flat on the steering column and press the ignition button. If you do this correctly, your system will notify the driver that the key is in use but still operational. Cost Although many car owners are switching to smart keys for greater convenience and security However, it's important to realize that these features aren't always cheap. It can be expensive to replace the lost smart keys and reprogram your car. replacement smart car key G28 Car Keys look like normal key fobs, however they are equipped with a microchip that can be used to unlock, lock or start a car without having a physical key. The chip transmits a unique code to the vehicle's system, which then recognizes the code and confirms it prior to beginning the engine. This technology has been around for a while, however it is not yet perfect. This technique has been employed by thieves to steal vehicles in several cases. There are ways to stop this from occurring. One way to prevent this is by using the smart key which has rolling security codes. The code changes every time the key is transmitted. A key fob with display screens can be extremely expensive. BMW's Display Key, a smart key with this kind of display, is an example. Its LCD color screen can perform all the functions of a typical key fob, including locking the door, unlocking it, and keyless start. However, it can also send commands to the vehicle via an iPhone. This makes it easier to operate the vehicle, and also keep in mind its charging and whereabouts. It can even tell the vehicle to park itself, which is a great feature for those with limited mobility or disabilities.
