Smart Car Key Fob Replacement: 11 Thing That You're Failing To Do
What Can a Smart Car Key Fob Do For You?
Known as fobs, keyless entry or smart keys, they were introduced by Mercedes in 1998. These computer-controlled key fobs can accomplish many things, including locking and unlocking cars and even starting it.
They operate by broadcasting an encrypted and rolling signal. This protects them from thieves with advanced technology.
Safety
A smart key fob continually communicates with vehicles through radiofrequency signals. It emits a low power signal that, when pressed the button, instructs the vehicle to open doors and begin the engine. The car is programmed to recognize the unique encryption code of a specific key fob. This means that even when the key fob is stolen, it won't be used to start the car.
A new hack allows thieves to take advantage of this type of communication. Relay attacks are carried out with devices that transmit at the same rate as keys. Thieves can put one of these devices in a purse or hiding area to disable the lock command from a distance, according to How Stuff Works Electronics. This is a risk that could become more frequent as more motorists change to smart keys.
A smart key fob isn't only a security feature but it can make your life easier by automatically taking care of the needs of your vehicle.

Instead, the driver needs to have it in their possession and bring it within the range of the vehicle, as explained by the BMW Group. Certain smart keys, such as the Display Key, have tiny LCD touchscreen that allows drivers to access features such as locking, unlocking, and keyless start directly from their key fob, without needing to connect to the Bluetooth system of the car.
Another way a smart key could help save time for drivers is by automating the process of locking their car doors when they leave. Consumer Reports says that this feature is available on many vehicles. It also makes it easier for drivers to maneuver into tight spaces without accidentally crushing someone or something.
Open Road Auto Group explains that smart key systems do not transmit the same frequency signal over and over in order to make them more vulnerable to relay attacks. In this way it is impossible for a stolen car to be hotwired even if it's equipped with a smart key because the encrypted signal that the key fob transmits is unique to each car. This makes it extremely difficult for thieves to steal a car.
Security
Today's newer cars pack in more advanced electronic features than ever before, and some of them are contained on the key fob. These gadgets do much more than simply lock and unlock doors or make chirping sounds to assist drivers in finding their car in a parking space, but some owners may not be aware of all the things these smart key fobs are able to do.
For instance, some smart keys are able to activate windows that are automatically opened and sunroof once they are pressed. A Auto editor of CR once walked out to her Honda Accord only to find all the windows down and sunroof up. This was one of the reasons she was grateful for her Smart Key, which locked the vehicle automatically.
Some smart keys use computer-encrypted signals to stop car thieves According to How Stuff Works. This technology blocks hotwiring, which thieves steal a vehicle's engine controller module (ECM) which is usually located at the front of the engine. The ECM controls many vital functions such as engine power, transmission control, and many more.
Smart keys also have anti-theft codes and a unique ID security code assigned to each key. This will disable ignition if the wrong key is used. The security ID is a number that is transmitted by the ECM from the key to the ignition, and then verified by a sensor located in the car.
Maintenance

Like all electronic equipment, a smart car key fob needs regular maintenance to function correctly. Key fobs that are modern have indicators for batteries that notify the driver when the battery is running low. It's simple to replace the battery and you don't require special tools.
In some instances the smart key could stop functioning entirely. If try this suspect this to be the case, try to reset it by taking the car out and then re-entering it. This will allow the car to know that the key fob remains in the vehicle and let it regain functionality.
