Like transponder keys. They have built-in chips that prevent unauthorised copies of keys from starting your vehicle.

These are some of the most secure keys you can purchase for your car, as they are extremely difficult to duplicate and can only be cut by the dealer or a certified locksmith.

Smart Keys

Unlike the traditional single piece of metal, smart keys make use of radio-frequency identification, or RFID to connect with the car. They come with a chip with an unique code that is encoded on every key. When you open your car doors or pop the trunk key, it transmits a signal to your car's onboard computer. The computer then triggers the correct frequency, allowing you to access your car and start it.

The smart key's chip also comes with a variety of security features that guard against theft. First the key emits a very low-frequency signal that can't be detected by any other receiver, not even your car. If the onboard computer detects this signal, it will prompt another one that is an individual sequence that only your car can understand. This will stop a criminal with a high-tech background from using an external pulse generator to "fool" the system and make the key work for other vehicles.

In addition to locking and opening the car, some smart keys have special features like storing specific driver preferences remote opening windows or the sunroof, and many more. These functions can be accessed by activating the proximity sensor on the key fob by pressing a button, or, in some instances it is as simple as twisting a tiny piece of metal inside the key.

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

Replacing a key with a smart chip typically requires a visit the dealership, where they will either have the replacement on hand or order it for you. The dealer will also have to program the new key to recognize your vehicle. You can also go to a locksmith for the replacement key fob to be programmed and then replaced.
