Smart Keys

Smart keys communicate with the vehicle via radio-frequency identification (RFID) instead of the traditional single piece of carved metal. This means they come with tiny chips that contain an encrypted code that is unique to each key. The key sends a signal to the computer onboard of your vehicle each time you unlock the doors or open the trunk. The computer will then signal the correct frequency to allow you to start your car.

If the computer onboard detects this signal, it will prompt a different one that is a unique sequence that only your car can recognize. This will stop a tech-savvy criminal from using a pulse generator to "fool the system" and make the key work on other vehicles.

Some smart keys have special features, such as saving preferences for drivers and opening windows remotely, or the sunroof remotely, and many more. These features can be accessed by activating the proximity sensor on the key fob, pressing a button or, in some cases it is as simple as twisting a tiny piece of metal inside the key.

Certain key fobs can be opened by placing the dead key in a slot or by placing it near an inductive coil that is located on the dashboard. Some even come with an emergency (fully mechanical) key blade hidden in the key to activate this.

Replacing a smart lock typically requires a visit to the dealership, who will either have the replacement on hand or purchase it for you.
