What You Should Know About Smart Keys Smart keys, also referred to as keys that are digital or information keys, allow drivers to access their vehicle without the need to use traditional keyholes. Certain cars come with them as standard features, whereas others offer them as an upgrade option. The technology is better than the traditional key fob, too. Certain systems have emergency start capabilities that allow you open the car and start the engine without having a key fob (or even an old-fashioned one). The most effective ones also have battery indicators which warn you ahead of time when the battery is about to expire. Security Smart keys are more efficient than traditional fobs, and also come with additional security and safety features. They connect to the computer system of your car using radio-frequency identification (RFID). An antenna on your car receives the signal from your key when it is in distance, allowing you unlock your doors and start the engine without taking out your phone or press a button. This may seem like a convenient feature. However, thieves can penetrate this system and unlock your doors and even start the engine. Certain manufacturers employ a technique known as “rolling codes” which prevent this from occurring. The code is projected by the key onto the starter and is then verified by the computer in the car before it starts. This stops thieves from making multiple copies of the key. Another way to keep your car safe is to make sure that you don't put the key and mobile phone in the same pocket. Placing the two devices too close can block the signals, thus preventing them from sending signals properly. The KeySmart Pro is a great option to do this since it has a built-in Tile that helps you locate your phone. If you have the application installed on your iPhone and you put the Smart Key near it, pressing its activation button triggers the Tile to emit short melodies and flash an LED. This could be life-saving in the event that you lose your phone or it's on silent mode. Convenience Smart keys can be used to store and remember personal settings such as seat, mirror and steering wheel settings. Some, like BMW's Comfort Access, even allow you to start your car without having to hit the ignition button. Modern smart keys communicate with car's antennas by using radio waves. They send a unique encrypted message that is interpreted and acted upon by the computer. These signals can be programmed to perform different functions like opening and closing the trunk, or activating children's locks. This technology is not foolproof. Cybercriminals with the right skills can steal the unique identification number of a smartkey by picking up its frequency transmission. Thankfully, the manufacturers are trying to make the system more secure. A useful feature is that you can remotely lock and unlock your vehicle by pressing the screen of your phone. This will save time when loading up children or cargo. This can be especially helpful if you are an adult with teenagers who are just learning how to drive. The sleek compact design of a smartkey is one of its most appealing features. This makes it easier to carry than other key organizers that can be bulky and take up more space than is needed. The KeySmart is quiet and comfortable to use, and eliminates the annoying jingle. Battery Life Smart keys are typically half as long (two to three years) versus four to six years) as regular fobs. This is because smart keys need to communicate with the car more frequently and at a higher speed to unlock and turn it on. Smart keys also consume more energy when placed close to electronic devices that generate electromagnetic fields such as phones, computers, and screens. Fortunately, most smart keys have batteries backup features. According to Open Road Auto Group, most have an emergency blade that works as traditional keys to open the door for the driver in the event that the smart keys fob batteries die. A majority 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. Another feature of smart keys is called an “power saving mode.” If you forget to take your smart key with you while driving, you can drive your vehicle as long as the engine isn't running. To achieve this, you should place the smart key flat against the steering column of your vehicle, while pressing the ignition button one time. If you've done this correctly, your system should inform the driver that the key is not working but it's still functioning. Cost Many car owners are switching to smart keys for convenience and increased security It's important to understand that these features aren't cheap. If you lose a smart key it could cost you a fortune to replace it and then reprogramme your vehicle. Smart keys resemble normal key fobs, however they contain a microchip, which allows you to unlock, lock or start a car without having a physical key. The chip transmits a unique number of digits to the car's system that recognizes it and validates it prior to beginning the engine. This technology has been in use for some time, but it's not the perfect solution. There have been numerous instances of thieves taking vehicles using this method. The good news is that there are ways to prevent this from occurring. One way to prevent this is by using an electronic key that contains rolling security codes. The code is changed each time the key is sent. A key fob with an LCD screen can be extremely expensive. BMW's Display Key is an example of this type of smart key. smart car key replacement serves the typical functions of a key fob, such as locking, unlocking, and keyless start, but it can also send commands from a smartphone to the vehicle's systems. This allows you to use the vehicle, and keep track of its charging and location. It is also able to command the vehicle to park itself which is a wonderful feature for people with limited mobility or disabilities.
