The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for your particular car.
This prevents the vehicle from starting by either hot-wiring or by altering the key. 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.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren.

When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is paired. The receiver compares the information with the 'allowed signals' stored on the key fob and then opens or locks the car door. If the information does not match the fob's information, the car won't be allowed to drive.
Once the car is paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look similar. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
