  2. Transponder Keys: These secrets include a plastic head that houses a little electronic chip. When the key is placed into the ignition, the car's computer system sends out a signal to the chip; if the chip does not respond with the appropriate code, the engine will not begin.
  3. Switchblade Fobs: These systems combine the electronic remote and the physical key into a single folding part. They are typically found on European models like Volkswagen and Audi.
