Transponder Chips

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still evade this system by using a specific device that detects the signal.
As you can see, there are quite a number of advantages to having transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and minimize the risk of theft.
