When activated by an electro-magnetic field, the chip emits a low level signal. The signal is taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.

This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key also proves that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

A circuit within the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer, allowing the engine to start.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the programing car keys with which it is paired. The receiver compared this information to the signals that are allowed in the fob and then either opens or locks the door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, even though they appear identical. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.
