10 Things You Learned In Kindergarden To Help You Get Smart Car Key Fob Replacement
What Can a Smart Car Key Fob Do For You?
Mercedes introduced the first fobs in the year 1998. They are also referred to as smart keys, keyless entry or keyless entry fobs. Key fobs that are controlled by computers perform many tasks, including locking and unlocking cars and even starting it.
They transmit an encrypted and rolling message. This makes them more receptive to thieves who are tech-savvy.
Safety
A smart key fob communicates with a vehicle through radiofrequency waves. It emits a low power signal that, when pressed, tells the vehicle to open doors and start the engine. The car recognizes the unique encryption code of a particular keyfob. This means that even when the key fob is stolen, it cannot be used to begin the car.
A new hack allows thieves to take advantage of this communication. Relay attacks are based on devices that transmit on the same frequency as the key fob. How Stuff Works Electronics says that thieves could put one of these devices in a pocket or hidden spot to stop the key fob's lock command remotely. This is a risk that could become more commonplace as more people switch to smart keys.
In addition to these security features, smart key fobs can make life easier by automatically adjusting to your vehicle's needs. For example the key fob connected to your smartphone will detect your presence and open the doors, so you don't have to press a button on the remote. It can also sense that you are leaving the car and lock it, so you won't forget to lock the doors. Many smart key fobs feature an indicator for the battery that warns you when the battery is not fully charged. The replacement of the battery in the majority of models is an easy and simple procedure that doesn't require any special tools.
Convenience
Smart keys do not have to be physically inserted into an ignition slot to open or start the car. BMW Group explains that the driver just needs to bring the key within range of the car. In fact, some smart keys, such as the Display Key, feature small LCD touchscreen with color that allows users to access features like locking and unlocking, as well as keyless start directly from their key fob without needing to connect to their car's Bluetooth system.
Another way smart key s can help drivers save time is by automatizing the process of locking their doors when they leave it. Consumer Reports says that this feature is present on a variety of automobiles. It can also make it easier for drivers to maneuver around tight spots without accidentally squeezing someone or something.
Additionally, smart key systems do not typically transmit the same frequency signal repeatedly and this can make them more vulnerable to relay attacks, says Open Road Auto Group. As such, a stolen vehicle cannot be hotwired if it is 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 the car.
Security
The latest cars are equipped with the most advanced electronic features ever before, and a few of them are found inside the key fob. These devices can do much more than locking and unlocking doors or making chirping sounds to help motorists locate their car in parking areas. However certain owners might be unaware of the full capabilities.
For instance, certain smart keys are able to activate windows that automatically open and sunroof when they are activated. A CR auto editor once walked out to her Honda Accord only to find all the windows shut and the sunroof opened. She was thankful for her Smart Key that automatically locked the car.
Some smart keys employ computer-encrypted signals to stop car thieves according to How Stuff Works. This technology prevents hotwiring, in which thieves take the vehicle's engine control unit (ECM) that is usually located on the front of the engine block. The ECM is responsible for many important functions including engine power, transmission control, and other functions.

Smart keys also include anti-theft codes and a unique ID security code that is assigned to each key. This will disable ignition when the wrong key is used. The security ID is a code that's transmitted from the ECM to the key when it's inserted in the ignition, and is confirmed by a sensor in the car.
Maintenance
A smart car key fob can do more than just unlock your door. It can remotely start your engine, turn on the brakes and suspension and even start your vehicle. It also gives you information about your vehicle, like fuel level and the temperature of your oil.
Like any piece of electronic equipment like a smart car key fob needs regular maintenance in order to function properly. Modern key fobs include battery indicators to alert the driver when it is time to replace the battery. It is easy to replace the battery and you don't require special tools.
In some cases the smart key might stop working completely. If you suspect this is the case, attempt to reset it by getting out of the vehicle and then returning inside. This will enable the car to understand that the key fob is still in the vehicle and let it regain functionality.
Contact a locksmith if you are unable to get your key fob to work. They can reprogram it so that the car recognizes it once more and allows you to utilize all of its features. It's typically more affordable to do this than buying a new key fob and it could save money in the end. In some cases locksmiths are able to fix an existing fob so that it can be used to make an entirely new key. This can save you more money in the long run.
