The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip inside the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.

If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.
When a car is connected with a specific fob, it will only accept signals from the device that is associated with it. In turn, other fobs will not work with the vehicle even if they appear similar.
