2. Transponder Keys

Presented in the mid-1990s, these secrets include a little RFID (Radio Frequency Identification) chip in the plastic head. When the key is turned in the ignition, the car's computer system sends a signal to the chip. If the chip doesn't react with the right code, the engine will not begin.

3. Laser-Cut Keys

Likewise called "sidewinder" keys, these have a distinct winding slit cut into the center of the blade instead of notches on the edges. They are thicker and require pricey laser-cutting equipment to duplicate.

4. Key Fobs and Remote Heads

5. Smart Keys (Proximity Keys)

Found on most modern cars with "push-to-start" buttons, these are not secrets in the traditional sense. They are sensing units that permit the vehicle to be operated as long as the fob is within the cabin or a certain radius.
