Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down.

These kinds of thefts have drastically reduced with the introduction of the transponder chip.
When you place the transponder key in the ignition the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed with the frequency of the chip in the key.
