2. Transponder Keys

Introduced in the late 1990s, transponder secrets feature a plastic head that houses a small RFID (Radio Frequency Identification) chip. The engine will not begin unless the car's immobilizer system recognizes the specific code transferred by this chip.

3. Remote Head Keys

These systems integrate the physical key blade with the push-button control buttons into a single piece of hardware. While they are convenient, they are more expensive to change than fundamental secrets due to the fact that the whole unit should be changed if either the blade or the electronic parts stop working.

4. Smart Keys (Proximity Fobs)

Most modern-day vehicles utilize wise keys. These devices do not need a physical key to be inserted into a slot. Rather, the vehicle detects the presence of the fob when it is in close distance, enabling the driver to unlock the door by touching the handle and begin the engine with a button.
