What Can a Smart Car Key Fob Do For You?

Mercedes introduced the first fobs back in 1998. They are also referred to as smart keys, keyless entry, or keyless entry fobs. These key fobs controlled by computers can accomplish many things, including locking and unlocking a vehicle and even starting it.

They function by broadcasting an encrypted and rolling signal. This makes them more resistant to hackers with a technological edge.

Safety

A smart key fob communicates with vehicles through radiofrequency signals. It emits a low power signal that, when pressed, tells the vehicle to unlock doors and start the engine. The car recognizes the encrypted code of a particular keyfob. This means that even in the event that the key fob gets stolen, it cannot be used to start the car.

But a new form of hacking technique can permit thieves to take advantage of that communication. Relay attacks employ devices that transmit on the same frequency as the key fob. How Stuff Works Electronics says that a burglar could slip one of these devices inside pockets or in a hidden place to block the remote lock command. It's a problem that could become more commonplace as more drivers adopt smart keys.

Aside from these security features, smart key fobs can simplify your life by automatically tending to your vehicle's needs. For example the key fob linked to your smartphone could detect your proximity and unlock the doors, meaning that you don't have to hit the remote button. It can also tell when you're leaving and auto-lock the car, meaning you don't have to worry about forgetting to lock the doors. A majority of smart car key recoding (view site…) key fobs have an indicator for batteries that tells you when the battery is low. Most models allow you to replace the battery quickly and easily without the need for any special tools.

Convenience

In contrast to a traditional key made of metal smart keys do not require physically inserting into the ignition slot to unlock or start the vehicle. Rather, the driver simply must have it on their person and have it within reach of the vehicle, as explained by the BMW Group. Some smart keys for cars keys, like the Display Key, have small LCD touchscreen that gives users access to features such as locking, unlocking and keyless starting directly from their key fob without needing to connect to the Bluetooth system in the car.

Another way smart keys could help save time for drivers is by automatizing the process of locking their car doors when they leave. Consumer Reports says that this feature is offered on a number of vehicles. It can also make it easier for drivers to maneuver into tight spots without accidentally pushing someone or something.

Open Road Auto Group explains that smart key systems don't transmit the same frequency signal repeatedly in order to make them more vulnerable to relay attacks. Smart keys are specific to each vehicle, so a stolen car cannot be connected to a hotwire. This technology makes it extremely difficult for thieves to steal a vehicle.

Security

Modern cars have the most advanced electronic features ever before, and many of them are found in the key fob. These devices can do much more than simply locking and unlocking doors, or making chirping sounds to help drivers locate their vehicle in parking spaces. However, some owners may be unaware of the full capabilities.

Certain keys, such as instance, will activate the auto windows and sunroofs of an automobile when pressed. A Auto editor of CR once walked out to her Honda Accord only to find all the windows closed and the sunroof opened. This was one of the reasons she was grateful for her Smart Key, which locked the vehicle automatically.

According to How Stuff Works, some smart car key replacement keys utilize computer-encrypted signals to protect against car thieves. This technology stops hotwiring in which thieves steal the engine controller module (ECM) typically located in front of the engine. The ECM controls many vital functions such as engine power, transmission control, and more.

Other technologies used in smart keys include anti-theft coding and an individual security ID assigned to each key, which can disable the ignition if it's not the right one. The security ID is a special code that is sent from the ECM to the key when it's inserted into the ignition. It is then verified by a sensor inside the car.

Maintenance

A smart car key fob can do much more than unlock your door. It can remotely start your engine, activate suspension and brakes, and even start your vehicle. It also gives you information about your vehicle such as fuel level and the temperature of your oil.

Like all electronic equipment the smart car key fob requires regular maintenance to ensure it functions effectively. Key fobs that are modern have indicators for batteries that notify the driver when the battery is low. Replacing the battery is a simple procedure, and no specialized tools are required.

In some instances, however, a smart key could stop functioning completely. If you suspect that this is the cause, try to reset the smart key after leaving the vehicle, then returning inside. This will enable the car to understand that the key fob is still inside the vehicle, and allow it to function again.

Contact a locksmith if are unable to get your key fob working. They can reprogram the fob so that it is recognized by the car and you are able to use all its features. It's usually more cost-effective to do this than buy an entirely new key fob and it can save you money in the end.
