Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down.

These types of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert the transponder key into the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to read the specific frequency of the chip inside the key.
