Transponder Chips

When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for your specific vehicle.
This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be received by the chip and cause it to send a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and notify you via flashing lights and siren. This is designed to discourage people from attempting to hack into the vehicle, however it's not a 100% security measure.

After the car has been connected to a specific fob, it only accepts signals from that device. Other fobs won't work with the car, even though they look similar. This ensures the security of the computer system in the car and blocks the use of unauthorized key fobs to gain control over it.
