Transponder Chips

Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are microchips in the form of computers that emit low-level radio signals. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been an enormous success in preventing theft of cars. It has also saved many car owners a significant amount of money as they don't need to replace their cars.

In the past, thieves would force the ignition switch of your car into the "on" position using a flat screwdriver or even use hot wires to disable the system entirely. These kinds of thefts have been drastically reduced with the introduction of the transponder chip.

When you place the transponder key into the ignition the signal is picked up by an antenna hidden around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The onboard computer of the car will then recognize the key as being valid and allow fuel flow, power the starter or start the engine.
