Some vehicles come with them as standard features, and others offer them as an upgrade option. The technology is also more modern than a traditional fob.

Security Smart keys are more practical than traditional key fobs and come with additional security and safety features. They make use of radio-frequency identification, or RFID, to communicate with your car's computer system. An antenna mounted on your car reads the signal from the key when it is within range, 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 convenient feature however, thieves could also hack into the system to unlock your doors and then start the engine. Some manufacturers use a technology known as “rolling codes” which prevent this from happening. The code is projected by the key onto the starter and later verified by the computer in the car before it begins. This stops thieves from making multiple copies of the key. You can also ensure your vehicle is safe by not putting your phone and the key in the same pocket. Putting the two devices too close can block the signals, which can stop them from communicating properly. The KeySmart Pro is a great option for this because it has a built-in Tile that lets you locate your phone. If you have the app installed on your iPhone and you place the Smart Key near it, the press of its activation button triggers the Tile to emit short melodies and flash an LED. This can be a lifesaver when you've lost your phone in a dark room or even if the phone is on silent mode. Convenience In addition to locking and unlocking your vehicle, a smart key can also store and remember individual settings such as mirror, seat and wheel position. Certain smart keys, like BMW's Comfort Access system, allow you to start the car without pressing the ignition button. Modern smart keys communicate with the car's antennas using radio waves. They send a unique encrypted message that is then interpreted and processed by the computer. The signals can be reprogrammed to perform various functions like opening and closing the trunk or activating a child lock. The technology isn't completely foolproof However, it's not completely foolproof. Cybercriminals with the right skills can steal the unique identification number of a smartkey through the frequency of its transmission. Fortunately, the manufacturers have been striving to increase the security of the system. Another benefit is the ability to remotely lock and unlock your vehicle using a simple tap of the phone's screen. This allows you to save time when loading children or cargo and can be especially helpful if you are a parent with teenage kids who are still learning to drive. One of the best aspects of a smart key is its sleek slim design. It's easier to carry compared to other key organizers, which can be bulky and take up more room than necessary. The KeySmart is quiet and easy to use, and eliminates the annoying jingle. Battery Life Typically smart keys last about half as long as regular keys with key blades (two to three years, versus four to six). Smart keys must communicate with the car at a higher frequency and at a higher frequency to unlock and start the car. Smart keys also consume more energy when placed near electronic devices that create electromagnetic fields like computers, phones and screens. Fortunately, many smart keys have battery backup features. According to Open Road Auto Group most smart keys have blades that can be used as a traditional door key in the event the battery of the smart key fob dies. Most also have a special slot where you can insert an old-fashioned key to turn on the engine in the event that the smart key is not functioning. Another feature of the smart key backup is called the “power saving mode.” If you don't remember to carry your smart key with you while driving, you can drive your car for as long as the engine isn't running. To do this simply lay the smart key flat on the steering column while pressing the ignition button. If you've done this correctly, the system will notify the driver that it's low on the key, but nonetheless functional.

This technology has been in use for a while, but it's not the perfect solution. There have been numerous instances of thieves stealing vehicles using this method. The good news is that there are solutions to prevent this from happening. One option is to utilize an intelligent key with rolling security codes, which changes the code each time it is transmitted. A key fob with a display screen is also very expensive. BMW's Display Key, a smart key of this kind, is an example. Its LCD color touchscreen performs the typical functions of a key fob such as locking, unlocking, and keyless start however, it can also transmit commands from an iPhone to the car's systems. This makes it easier to operate the vehicle, and also keep on top of its charging status and whereabouts. It even allows the vehicle to park itself.
