What You Should Know About Smart Keys

Smart keys, also referred to 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, whereas others offer them as an upgrade option.

The technology is also more advanced than a traditional key fob. Certain systems let you start the car without the traditional key fob or even a key. The best ones also have indicators for battery which warn you ahead of time when the battery is about to run out.

Security

Smart keys are more practical than traditional keys and also come with additional security and safety features. They make use of radio-frequency identification, or RFID, to communicate with your car's computer. If the key is within the range of the antenna it is able to unlock the doors and start the car without the need to use your phone or push the button.

While this may seem like a great idea however, car thieves can hack into the system to unlock your doors and start the engine. Some manufacturers use "rolling code" technology to block this. The code is projected by the key onto the starter and later verified by the computer in the car prior to it starting. This stops thieves from making multiple copies of the key.

Another way to keep your car secure is to make sure that you do not put the mobile phone and the key in the same pocket. Signals can be blocked when the two devices are placed too close.

The KeySmart Pro is a great alternative to this as it has a built-in Tile that helps to locate your phone. If you have the application installed on your iPhone and you put the Smart Key near it, the press of its activation button triggers the Tile to play an elongated melody and flash an LED. This can be life-saving when you've lost your phone or if it's on silent mode.

Convenience

Smart keys can be used to store and retrieve personal settings, such as seat, mirror and steering wheel positions. Certain smart keys, such as BMW's Comfort Access system, allow you to start the vehicle without having to press the ignition button.

Modern smart keys communicate with car's antennas by using radio waves. They transmit a unique encrypted message which is interpreted and then acted upon by the computer. These signals can be reprogrammed to perform different tasks, such as opening and closing the trunk, or activating the lock of a child.

The technology isn't 100% secure. It's possible for tech-savvy thieves to be able to identify the frequency transmission of an intelligent key and get its unique identification number. Fortunately, manufacturers are striving to make the system more secure.

Another benefit is the possibility to remotely lock and unlock your vehicle with a tap of the phone's screen. This allows you to save time when loading your children or cargo. This can be particularly beneficial if you're a parent of teens who are still learning to drive.

One of the most appealing features of a smart key is its sleek slim design. It is much more convenient to carry than other key organizers that can be bulky and take up more space than needed. The KeySmart is also quiet and comfortable to carry, eliminating the annoying jingle that can make you shiver.

Battery Life

Typically smart keys last for half as long as regular fobs with key blades (two to three years versus four to six). The Smart Car Key Recoding (Pediascape.Science) keys must communicate with the car at a much higher rate and more frequently to unlock and start the vehicle. Smart keys can also be drained faster if they are placed close to electronic devices such as phones, computers or screens that emit electromagnetic fields.

Most 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 key for doors in the event that the battery of the smart keys for cars key fob fails. Most have a slot where a traditional key can be inserted to start the engine in the event that the smart key fob isn't working or is dead.

A "power saving mode" is a different smart key backup. If you lose your smart car key reprogramming key while driving, your car will continue to function as long as it is not running. To do this, place the smart key flat on the steering column and press the ignition button. If you've done this correctly, your system should notify the driver that the key is depleted but still operational.

Cost

Although many car owners are converting to smart keys for convenience and increased security, it's important to know that these features aren't always cheap. If you lose a smart key, it could cost you a lot to replace it and then reprogramme your vehicle.

Smart keys are similar to regular keys but come with a microchip that can unlock, lock, or start the vehicle without the need for a physical key. The chip transmits a unique code the vehicle's system, which then recognizes it and verifies it before beginning the engine.

This technology has been in use for a while but it's not perfect. There have been a few instances of thieves stealing vehicles using this method. The good news is that there are methods to prevent this from happening. One method to avoid this is to use an electronic key that contains rolling security codes. The code changes every time the key is used.

A key fob that has display screens is very expensive. BMW's Display Key, a smart key with this kind of display, is a prime example. Its LCD color touchscreen performs the usual functions of a key fob such as locking, unlocking and keyless start however, it can also transmit commands from smartphones to the system of the vehicle. This allows you to use the vehicle, as well as keep track of its charging and the location of its battery. It can even tell the vehicle to park itself which is an excellent feature for people with limited mobility or disabilities.
