Transponder Chips
Transponder chips are in a variety of newer vehicles to prevent car theft. These are tiny computer microchips that emit low-level radio waves. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine.

These kinds of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert the transponder keys in the ignition the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow fuel to flow, turn up the starter, or even begin it.
