Safety
A smart key fob that communicates continuously with the vehicle via radiofrequency waves. It sends a low-power signal that, when pressed, signals the car to unlock doors and begin its engine. The car is programmed to recognize the unique encryption code of a specific key fob. This means that in the event that the keyfob is stolen, the car can't be started.
g28carkeys.co.uk allows thieves to exploit this type of communication. Relay attacks are based on devices that transmit on the exact frequency as the key fob. How Stuff Works Electronics says that thieves can put one of these devices into pockets or in a hidden place to stop the lock command remotely. It's a problem that is likely to become more prevalent as more people switch to smart keys.

Many smart key fobs feature a battery indicator that alerts 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 does not require any special tools.

Some smart keys, like the Display Key, come with tiny LCD touchscreen that allows users access to features like locking, unlocking and keyless start directly from their key fob, without the need to connect to the Bluetooth system of the car.
Another way that smart keys can help drivers save time is by automatizing the process of locking their car doors when they leave. This feature is present in many vehicles, according to Consumer Reports, and can also make it easier to get into tight parking spaces without causing injury to something or anyone.

Therefore a stolen vehicle can't be wired hot 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
A few of the most advanced electronic features in today's modern automobiles are included in the key fob. These devices are capable of more than just locking and unlocking doors or making chirping sounds to assist drivers locate their car in parking lots. However certain owners might be unaware of the full capabilities.
For instance, certain smart keys can trigger windows that automatically open and sunroof when hit. A CR auto editor once walked out to her Honda Accord only to find all the windows down and 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 blocks hotwiring, which thieves steal a vehicle's engine controller module (ECM) typically located at the front of the engine. The ECM controls a variety of important functions, including engine power and transmission control.
Smart keys also have anti-theft code and a unique ID security code assigned to each key. This will disable the ignition if the wrong key is used. The security ID is a digit that is transmitted by the ECM from the key to the ignition, and then confirmed by a sensor in the car.
Maintenance
A smart car key fob can do more than just unlock your door. It can start your engine and activate the suspension and brakes remotely. It also provides information about your car such as the fuel level and the temperature of your oil.
Like any piece of electronic equipment, a smart car key fob requires regular maintenance to function correctly. Modern key fobs include battery indicators to alert the driver that it is time to replace the battery. Replacing the battery is a straightforward procedure, and no specialist tools are required.
In certain instances, the smart key will cease to function completely. If you suspect this is the issue, try to reset the smart key after leaving the vehicle and coming back inside. This will allow the car to detect that the key fob is still inside the vehicle, and allow it to be used again.
Contact a locksmith in the event that you cannot get your key fob to function. They can reprogram your fob so that it is recognised by the car and you can make use of all its features. It's typically more affordable to do this than buy an entirely new key fob and it can save you money in the end.
