Contrary to conventional keys that are required to be inserted into the keyhole in order to unlock the car, smart keys make use of radiofrequency signals to communicate with your vehicle. They transmit encrypted data which allows you to unlock your car and even start the engine. They're even more secure than traditional keys since hackers will need to intercept the signal between your smart key and your vehicle which is not possible without the right equipment.
The smart key is useful because it performs a variety functions without having to reach for your phone or use an remote control. With an app on your smartphone, you can instruct your car to lock itself or open and close the trunk. The app can also transfer digital keys to other people such as babysitters, friends or even your own. BMW's Display Key is a good example. It is a small LCD color screen that performs the same functions as a key fob plus some unique features like self-parking.
Finally, all smart keys have a backup mechanical key blade that is hidden in the key fob. This is used to open a locked door in case the smart key battery goes out. The key blade is hidden beneath the cap made of plastic that is removable of the key fob.

It is simple to change the battery of a smart key and costs only a few dollars.
A smart key system creates encrypted signals that are not copied by a code-stealing device. The smart key emits these signals, which are interpreted by the computer inside the vehicle. The computer then checks the authenticity of the key and authorize it to begin the engine. This helps thwart car thieves.
Smart keys can be programmed in minutes with the assistance of a professional at your local Pop-A-Lock store. Beware of mistakes that could result in serious damage to your vehicle by following the steps carefully.

This is accomplished through an algorithm that determines if the driver and key are too far away from the vehicle. For instance fueling stations. The majority of smart keys have an overshoot limit of 10 centimeters for the LF field in order to reduce this risk.
Most smart keys will inform you when the battery is running low. Replacing the battery is an easy procedure and doesn't require special tools. Certain systems let you start your car even if you don't have a fob, which is helpful if you leave the car at home.
Make Sure You're Secure
A smart key makes use of radio-frequency identification (RFID) to connect to your vehicle. The chip inside the smart key is an identification code that can only be recognized by your car. If the key is close proximity, it transmits an encrypted code to the antenna of your car. This signal locks or unlocks the doors and starts the engine. If the key is not in range the car will shut off the engine and close its doors.

Open Road Auto Group explains smart keys emit a unique signal frequency each time they are utilized, which means that a person who has a different key is unable to get the signals to unlock your car.
Additionally, digital keys using UWB and BLE technologies--which aren't vulnerable to MITM attacks--are much more secure against theft. And, if you lose your digital keys you'll be able to still access your car via its smartphone app. A majority of digital car keys include indicators for the battery that will notify you when the battery is running low.
