The most effective ones also have battery indicators that alert you in advance when the battery is about to run out.

Security

Smart keys are more practical than traditional keys and come with additional security and safety features. They make use of radio-frequency identification, or RFID, to communicate with the computer system in your car. An antenna in your car reads the signal from the key when it's within range, allowing you to unlock your doors and start the engine without having to pull out your phone or press a button.

While this may seem like a great idea however, thieves could also hack into the system to unlock your doors and start the engine.

This helps prevent thieves from making multiple copies of the keys.

You can also keep your car secure by not placing the phone and keys in the same pocket. Placing the two devices too close to each other could block signals, stopping the devices from communicating correctly.

There are ways to stop this from occurring. One way to avoid this is by using an electronic key that contains rolling security codes. The code changes each time the key is transmitted.

Its color LCD screen performs all the functions of a typical key fob, including locking the door, unlocking it, and keyless start. But it can also communicate with the vehicle using a smartphone.
