When the key is placed into the ignition, the vehicle's engine control system (ECU) sends out a signal to the chip. If the chip does not respond with the proper digital code, the car will not begin.

3. Laser-Cut Keys

Also referred to as "sidewinder" secrets, these are differentiated by a thicker shank and a groove cut into the center of the blade instead of notches on the edges. They need expensive, specialized laser-cutting machinery to produce and normally include a transponder chip.

4. Key Fobs and Remote Heads

Many cars make use of a remote fob to lock and open doors, often paired with a separate mechanical key. Remote head secrets integrate these into a single system where the buttons are developed into the key's handle.
