Keep An Eye On This: How Smart Car Key Fob Replacement Is Taking Over The World And How To Respond
What Can a Smart Car Key Fob Do For You?
Mercedes introduced the first fobs in 1998. They are also known as smart keys, keyless entry or keyless entry fobs. The fobs that are computer controlled are capable of performing a variety of functions including locking and unlocking the vehicle or the car's start-up.
They work by transmitting an encrypted, rolling message. This keeps them safer from thieves who are tech-savvy.
Safety
A smart key fob communicates with vehicles by radiofrequency waves. It emits a low power signal that, when pressed the button, instructs the vehicle to unlock doors and start the engine. The car is programmed to recognize the unique encrypted code of a specific key fob. This means that in the event that the keyfob is stolen, the car cannot be started.
But a new form of hack can enable thieves to gain access to that communication. Relay attacks are carried out using devices that transmit at the same rate as key fobs. How Stuff Works Electronics says that thieves can put one of these devices into an unnoticed pocket or a hidden location to block the remote lock command. It's a problem that could become more commonplace as more drivers adopt smart keys.
Apart from these security options, the smart key fob can make life easier by automatically adjusting to your vehicle's needs. For example, a key fob that's connected to your smartphone will detect your proximity and unlock the doors, so you don't have to hit the remote button. It can also sense when you're leaving the car and auto-lock the car, so you don't have to fret about not locking the doors. A lot of smart key fobs have an indicator of the battery that tells you ahead of time if the battery is running low. Also, replacing the battery in most models is a straightforward and easy process that doesn't require any special tools.

In contrast to a traditional key made of metal, smart keys do not require physical insertion into an ignition slot to unlock or start a car. Instead, the driver needs to have it on their person and bring it within range of the vehicle, as explained by the BMW Group. Some smart keys, including the Display Key, feature a small 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 in the car.
Another way smart keys could help save time for drivers is by automating the process of locking their doors when they leave it. 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 spaces without accidentally crushing someone or something.
Open Road Auto Group explains that smart key systems do not transmit the same frequency signal repeatedly, as this can make them more susceptible to relay attacks. Therefore a stolen vehicle can't be connected to a hotwire if equipped with a smart key since the encrypted signal that the key fob transmits is unique to each car. This makes it very difficult for thieves to steal a car.
Security
A few of the most advanced electronic features found in the latest vehicles are found in the key fob. These gadgets do much more than just unlock and lock doors, or emit chirping sounds to assist drivers in finding their vehicle in a parking lot however, some owners might not be aware of everything the things these smart key fobs are able to do.
For instance, certain smart keys are able to activate a vehicle's automatic windows and sunroof when pressed. A auto editor for CR once went out to her Honda Accord only to find all the windows shut and the sunroof up. She was thankful for her Smart Key that automatically locked the car.
Certain smart keys use encrypted computer signals to thwart car burglars According to How Stuff Works. This technology stops hotwiring in which thieves steal the engine controller module (ECM) typically located at the front of the engine. The ECM controls many vital functions including engine power, transmission control and many more.
Other features of smart keys include anti-theft encryption and a unique security ID that is assigned to each key, which can turn off the ignition if it's not the right one. The security ID is a unique code that's sent from the ECM to the key once it's put into the ignition. It is then confirmed by a device inside the car.
Maintenance

Like any piece of electronic equipment like a smart car key fob requires regular maintenance to function effectively. Modern key fobs come with indicators for batteries that notify the driver when the battery is low. It is easy to replace the battery and you don't need special tools.
In some instances the smart key might stop working completely. If you suspect this is the issue Try to reset the smart key by removing the vehicle and coming back inside. This will allow the car to recognize that the key fob is still in the vehicle and will allow it to function again.
If you are unable to get your fob to function get in touch with a locksmith for help. They can reprogram it to ensure that your vehicle recognizes it and allows you to use all of its features.
