Transponder chips are in many newer cars to guard against theft of vehicles. These are tiny computer microchips which emit radio waves at a low level. The microchips have a unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be a huge success in preventing theft of cars. This technology has also saved car owners a great amount of money since they don't have to purchase new cars.

These types of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will then detect that the key is valid and allow fuel to flow, power up the starter, or even start it.
