Introduced in the mid-1990s, these secrets consist of a small RFID (Radio Frequency Identification) chip concealed inside the plastic head. When the key is kipped down the ignition, the car's computer sends out an electronic signal to the chip. If the chip does not respond with the proper code, the engine will not begin.
3. Laser-Cut Keys
Likewise called "sidewinder" secrets, these have a distinct thick blade with a meandering groove reduced the center rather than notches on the side. They are harder to pick and need specialized high-security cutting makers.
4. Remote Head Keys
These combine the transponder key with the buttons for locking and opening doors. The remote and the transponder are separate parts housed in one unit.
5. Smart Keys and Proximity Fobs
The most modern model, these do not need a physical key to be inserted into the ignition. As long as the fob is inside the automobile, the driver can start the car with a "Push to Start" button.
