Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft.

These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
